Right now, one of Jupiter's moons, Europa, is orbiting the largest planet in the solar system. This moon contains an ocean underneath its surface. This ice sheet massing across Europa will be used by scientists and other researchers to determine if the -260 degree Fahrenheit moon could sustain life.
NASA’s Hubble Telescope has revealed water vapor being exclusive to one hemisphere of Europa, which is irregular. This condition is one that scientists hope to exploit in order to determine how other planets, similar to the moon, host ice on their surfaces or below.
There is also evidence to suggest the water vapor has been present for an extended amount of time. This evidence stems from observations conducted by the Hubble Space Telescope between 1999 and 2015. In addition, the vapor is present exclusively in the tail-end of Europa’s orbit, meaning the hemisphere facing away from the direction of orbit. This evidence gives researchers and scientists several answers but probably also raises several more questions.

Did you know that storms form in places other than on Planet Earth? NASA has studied storms on planets in our Solar System for many years. And NASA continues to study large storms on Jupiter. In August of 2020, NASA’s Hubble Space Telescope captured images of another giant storm on the surface of Jupiter. Scientists refer to this area of storms as “Red Spot Junior.”
Jupiter is known as the “Monster Planet” due to its large size and turbulent atmosphere. While the pictures were being taken, NASA found that new storms were brewing on Jupiter and that the planet’s famous Great Red Spot region was preparing to change color once again.
The Hubble Space Telescope also captured another intriguing image of Jupiter. At around its mid-northern latitudes, Hubble located a bright white, and stretched-out storm traveling at around 350 mph. During this time, ground-based observers had also identified two more storms in the same region.

Titan, a moon of Saturn, will soon host a new drone mission by NASA, nicknamed “Dragonfly.” The mission will aim to answer questions related to the moon's Earth-like environment.
The Saturn moon only has 14% of Earth’s gravity but shares geological features such as valleys, mountain ridges, mesas, and dunes. During one recent mission, a probe broadcasted a 2.5-hour film to NASA as it descended into Titan’s atmosphere. The broadcast revealed the presence of ice and shorelines, similar to Earth.
Titan houses one of the only sanctuaries for living organisms to exist in this solar system. The organism in Titan has been labelled as tholins and are complex organic molecules that have been subjected to radiation and sunlight for long swathes of time.

After scientists expected its demise for a year, Leonard’s Comet, the brightest comet of 2021, has finally disintegrated. But its tumultuous journey to the sun has caused excitement among astronomers.
Comet C/2021 A1, generally referred to as Leonard’s Comet, began breaking apart after passing the sun on January 3, 2022 at perihelion, which occurs when a comet is at its closest to the sun.
Post-perihelion, the comet has lost its nucleus and its temporary atmosphere. The outermost layer of the once powerful comet has disintegrated.

Have you ever wondered how far away the most distant star is? Or how NASA discovers such distant things in our universe?
The Hubble Space Telescope is a partnership between NASA and the European Space Agency. During Hubble’s 32-year lifespan, it has helped NASA make more than 1.5 million observations. The Hubble, which has helped discover black holes, merging galaxies, interstellar objects, and even moons surrounding Pluto, is located 340 miles above Earth.
Thanks to this telescope, NASA managed to get their hands on an unprecedented image of the farthest star discovered so far, Earendel, which means “morning star” in Old English. NASA assumes that Earendel is about 50 times the mass of our sun and is millions of times more scintillating. The star appeared less than a billion years after the Big Bang which occurred around 13.8 billion years ago. The star is located 12.9 billion light-years from Earth. “We don’t know yet if it’s part of the very first generation of stars,” says Brenda Fyre, an astronomer from the University of Arizona and co-author of an article describing the discovery.

What are gas giants? Gas giants are large planets of relatively low density consisting predominantly of hydrogen and helium, such as Jupiter, Saturn, Uranus, and Neptune. These planets, unlike their counterparts, don’t have hard surfaces that are made from rock. Instead they’re comprised of “swirling gases and a solid core.”
For most of human history, our understanding of planets has evolved, primarily based on the eight (or nine) planets in our own sun system. Over the past 25 years, the discovery of more than 4,000 exoplanets, or planets outside our sun system, has changed our understanding.
There are common questions like, “Could a human ever live on a gas giant?” or “What would happen if a human went to a gas giant?” The answer to both questions is that humans would fall to their death because there is no solid ground to stand on. Also, because it is really hot, up to 20,000 degrees Farenheit or Celcius, people would certainly be incinerated.

The International Space Station is considered a constant symbol of humanity's achievements in the fields of space science and diplomacy. Many will be shocked to learn that the National Aeronautics and Space Administration (NASA) has plans to retire and crash the station straight into the ocean in 2031.
According to The International Space Station Report, NASA is aiming to crash the ISS into the Pacific Ocean at a location called Point Nemo, the farthest point at sea from any landmass. To put the distance in perspective, it is 2,000 miles North of Antarctica and 3,000 miles East of New Zealand. The ISS will, probably, rest forever at a point known as the spacecraft graveyard.
This retirement isn’t without merit, though, as NASA confirms that they intend to use the ISS as an “analog for a Mars transit mission,” according to a NASA report. The ISS was a point for which science could advance, which has included 3D printing an item on the orbiting station, producing the fifth state of matter, growing organic food in space, and sequencing DNA. Though the ISS will no longer be in orbit, the international scientific community will forever reap the information the station provided.

Dr. Mae Carol Jemison, an incredible engineer and doctor, was the first African American woman astronaut to go to space. Jemison spent her career with NASA and to this day she is respected by people all over the world. Mae Carol Jemison
Mae Jemison was born in Decatur, Alabama in 1965. She grew up with her mother and father, Charlie and Dorothy Jemison. She was the youngest of three children and soon after she was born, her entire family moved to Chicago, Illinois.
Mae always knew she wanted to study science. When she was young, she would watch on TV various space-related content and events such as the Apollo space missions. Mae always wondered why there were no women astronauts and was certain that she would travel to space one day.

Have you ever seen a rocket go into space and wondered how it worked?
Rockets usually have about three different engines that help them reach space. They get their power from burning fuel. This creates super hot gas that lifts the rocket into space.
All three engines make sure the rocket reaches its goal. When the first engine has used up its fuel, it drops away. Then the second engine takes over and does the same. After the second engine drops off, the third engine takes over and uses its fuel to reach space.

Scientists have recently discovered an asteroid that orbits the Sun even closer than Mercury. It is known as 2021 PH27.
The asteroid is about one kilometer in diameter and it gets as close as 20 million kilometers from the Sun where the temperature reaches about 900 degrees Fahrenheit, hot enough to melt lead.
2021 PH27 orbits the Sun in an inclined and elliptical shape; the orbit lasts 113 days and crosses the orbits of Mercury and Venus. This orbital period is the shortest yet discovered, making 2021 PH27 one of the fastest asteroids in our solar system.

Many people know what galaxies are, however, many do not know what makes up a galaxy or what they contain. The galaxy is made up of three main things. Let's begin with stars and gas. Our galaxy has arms made of bright stars and glowing clouds of gas that curl into a spiral shape. Galaxies contain billions of stars, more than we could ever count and between all the stars there is empty space.
Everything within a galaxy creates one of three unique galaxy shapes: spiral, elliptical and irregular. Spiral galaxies look like pinwheels, such as the Milky Way. The middle looks like a disk and the older stars are in the center. The youngest stars are in the arms outside since that’s where gas and dust meet to create new stars.
Elliptical galaxies are shaped like a loaf of bread or football. Did you know that most of the stars are in the middle? There are more elliptical galaxies than the other types of galaxies. Unlike spiral and elliptical galaxies, irregular galaxies aren’t formed in any distintable shape. These galaxies seem chaotic in shape since they are created when various galaxies collide with another. Although this sounds scary, it is not a big deal since it is mainly empty space between the stars and planets. Interestingly, our Milky Way galaxy will collide with the Andromeda galaxy, the Milky Way’s nearest galactic neighbor, in about five billion years.

One of the most common questions scientists are asked is will we ever be able to live on a planet other than Earth?
This question remains unanswered, but scientists have identified planets humans could possibly live on. Although they have yet to figure out all the factors that humans would need to survive on another planet, scientists have taken a new approach for evaluating the type of planet that would be survivable for humans.
Titan, one of Saturn’s moons, could possibly be our next home. It might sound crazy; it’s hard to imagine that humans could live any other place than Earth. Temperatures on Titan can reach almost 300 degrees below zero and methane and ethane rain from the sky before flowing into hydrocarbon seas. Titan might be the only orbital system in our solar system (other than Earth) where we would be able to build a permanent, self-sufficient human settlement.

For thousands of years observers have looked up at a sky full of galaxies and stars. Ancient people saw bright dots in the night sky and began to give them names.
In modern times we call these dots in space ”planets” and their names come from the Roman gods. Jupiter, the king of the gods, and Venus, the goddess of love and beauty. Saturn is the father of Jupiter and the god of agriculture.
Ancient observers also saw comets with sparkling tails, and meteors that seemed to fall from the sky. It’s easy to see why these first astronomers thought the gods were very powerful.

During 2019 and 2020, the new Hubble space telescope helped scientists gain new understanding about the mysteries of Jupiter. Best known as the planet with the Great Red Spot, Jupiter is the largest planet in our solar system. The Hubble telescope is now sending fascinating images to researchers here on Earth.
Jupiter gained its name years ago as a tribute to the king of the gods in Roman mythology. In ancient Greece, they named the planet after Zeus, the king of the Greek pantheon. In 1610, the astronomer Galileo Galilei discovered Jupiter’s four largest moons—Io, Europa, Ganymede, and Callisto, which are known as the Galilean moons.
Today we know that Jupiter has 79 moons in total, all named after figures in Roman mythology. Ganymede is the largest moon in our solar system, having a magnetic field and being bigger than both Mercury and Pluto. This moon has at least one ocean between layers of ice.

Scientists have found a surprising new discovery. In 2019, a new stellar black hole, said to be 70 times bigger than the sun, was found by a Chinese-led research group. “Black holes of such mass should not exist in our galaxy according to most models of stellar evolution,”said Lui Jifenq, a professor at the National Astronomical Observatory in China.
Joel Bregman, an author and professor of astronomy in the University of Michigan stated, “No one has ever seen a 70 solar mass stellar black hole anywhere.” The new discovery is named LB-1, which is located 15,000 light years away from Earth.

Pluto was discovered in 1930 by Clyde Tombaugh. Pluto was once considered the ninth planet but was demoted to a dwarf planet in 2006.
On June 22nd, 1978, an American astronomer named James Christy discovered that Pluto has a large moon and is very tiny and frosty in comparison to other planets. For this reason, scientists believe Pluto is actually not a planet at all, but a frosty planetesimal.
Frosty planetesimals were most likely formed inside the Kuiper Belt. The amount of gravity belonging to the gas giants sent most of them flying around planets. Most planetesimals were destroyed inside collisions, while some turned into moons. Other planetesimals that were tossed out formed space’s Oort Cloud.

Scientists have recently discovered a white dwarf star, the smallest to ever be found. A white dwarf star is formed when a star runs out of fuel and collapses in on itself, but is not heavy enough to collapse into a black hole.
An astrophysicist at the California Institute of Technology, Ilaria Caiazzo and her scientific team discovered this dwarf star. Caiazzo found the star using the ZTF (Zwicky transient facility) which is only used at the Palomar Observatory of California. The ZTF finds objects in space by looking at how they change in brightness. After their discovery, these astrophysicists gave the star its scientific name, J1901+1458.
The white dwarf star is the smallest star known in space. The star is about 130 light years away from Earth. The star’s average radius is about 2,140 kilometers, just slightly bigger than the Moon, and much smaller than the Earth. Despite being so tiny, this star is very heavy. Its mass is about 1.3 times the mass of our Sun.

Throughout the past couple decades, women have slowly begun achieving equality in the STEM fields. While these male-dominated industries are by no means perfect, there are more opportunities than ever before for women who want to pursue a career in science. However, this battle is by no means a recent one. In fact, women have been fighting for equality and recognition in STEM for centuries.
Maria Mitchell, born in 1818 to a progressive, American family, made giant leaps for women in astronomy. As the daughter of an amateur astronomer, she learned at a young age how to operate sextants, telescopes, and could even predict precise planetary and solar positions by her teenage years. Although she was a prodigal astronomer, she spent most of her early adulthood teaching. Like her father, astronomy was only a side hobby.
However, she soon propelled to professional astronomer status after making a revolutionary discovery: a newly-discovered comet. This led to massive publicity, and she became not only a renowned astronomer, but a feminist icon. Her monumental discovery in an almost entirely male-dominated field challenged the idea of innate male superiority, and she was invited to speak at the women’s rights conference in Seneca Falls in 1848.

Identified by Edwin Hubble, the Local Group is the nearest cluster of galaxies to the Milky Way. Currently, astronomers can identify 35 Local Group galaxies. These galaxies are connected by the force of gravity and are spread across 10 million light-years of space.
The Milky Way and the Andromeda galaxy are the largest in the Local Group; each has a small group of Local Group galaxies. The Andromeda Galaxy contains Local Groups such as M32, NGC 147, NGC 185, NGC 205 and 14 dwarf galaxies. By comparison, the Milky Way has satellite galaxies known as the Large and Small Magellanic Clouds along with some dwarf galaxies.
There are multiple “local groups” surrounding ours; one of the largest is being held in the constellation of Virgo. In combination with various clusters, the Local Group and constellation of Virgo form the Local Supercluster which stretches 60 million light-years across.

The Sun has a family called the Solar System. The family includes the planets Neptune, Saturn, Uranus, Pluto, Mars, Jupiter, Earth, and Venus. All the planets are of different sizes, shapes, and temperatures. However, despite their differences, they all stay in orbit due to the sun’s gravity.
The Sun’s family stays together by gravity. Each planet has its own gravitational force which pulls each other close and makes sure they do not leave their orbit. The 4 planets closer to the sun are dense balls of rock since it’s too hot for anything else to be sustained. The other 4 planets are way bigger and made of gas and liquids. The planet at the end of the Solar System, Pluto, is a solid and icy ball since it is furthest from the sun and doesn’t receive much heat. What makes every planet special is where they’re located in the solar system.
The Earth has one moon and it orbits the Earth while the Earth orbits the sun. Pluto has one moon while Mars has two moons. Mercury and Venus do not have any Moons. In a way, all the large gas planets have their own miniature “solar system.”

As the years pass and technology continues to improve, the possibility of humans one day living on Mars doesn’t seem that far away.
Mars and Earth have many similarities and differences. Mars is a neighbor to Earth, just 49 million miles away. Like Earth, Mars has seasons, days, and varying temperatures however the lengths and degrees differ. A day on Earth lasts 24 hours but a day on Mars lasts 24 hours and 37 minutes. The temperatures on Mars can vary from 68 degrees Fahrenheit in some areas during the summer to -284 degrees Fahrenheit during the winter, making it much colder than the Earth’s winter weather. If humans were to go to Mars and didn’t have a spacesuit, they would not get enough oxygen and their blood would start boiling rapidly.
When it comes to the atmosphere, Mars’ dry winds can reach speeds of up to 125 miles per hour, causing it to become dusty. In fact, it’s this dust with its high iron content that gives the planet its nickname “The Red Planet”.

The days of daydreaming are over. When the world’s first space hotel arrives, it will allow passengers to explore the unknown, while giving the same comfort you would get on Earth. In 2019, the Gateway Foundation, a Californian company run by John Blincow, planned on releasing a cruise ship style hotel that could one day hover over Earth’s atmosphere.
Tim Alatorre, senior design architect at Orbital Assembly Corporation, explained that the hotel, named the Voyager Station, will work by pushing contents of the station out to its perimeter, just like if you were spinning a bucket of water. The water will stay in place because the gravitational force pushes it against the bottom of the bucket, just like the people in the hotel. Alatorre also explained that there is no gravity near the center of the station, but as you move toward the outer part of the station, the force of gravity increases.
The Voyager Station was originally called the Von Braun Station because it was inspired by 60 year old designs from Wernher Von Braun, an aerospace engineer who launched rocket technology in Germany and later in the US. While in Germany, Von Braun was involved with Nazi Rocket Devepment Program. The name was later changed to Voyager Station to avoid any connections to Von Braun’s Nazi affiliated past. John Blincow said, “the station is not really about him. It’s based on his designs and we like his contributions towards science and space.”

Scientists recently found substantial evidence that there could be life on Venus. They do not believe it to be like life on Earth, but life in some different form.
Scientists found the gas phosphine on Venus. It is produced on Earth by microbes and can be found in swamps. The scientists discovered phosphine 62 kilometers above Venus's surface in the cloud layer. Scientists say that the phosphine has to be continuously made or else it would be destroyed within 1,000 years. This is why they think the presence of phosphine could be a sign of life on Venus.
Venus’s surface is extreme and too hot for humans. Temperatures can reach 470 degrees Celsius. Unlike Earth, Venus has a constant cloud layer.

A group of 250 Madison scientists from the Sierra Nevada Corporation (SNC) are working with NASA to develop systems that provide an optimal environment for growing produce in space.
Growing plants in space is a challenge, due to the lack of sunlight and gravity. Without sunlight, the plants can’t photosynthesize, and without gravity, seeds can float away and water can’t get to the plants’ roots. SNC’s solution to this problem is the Advanced Plant Habitat. The Advanced Plant Habitat is a closed and controlled environment that the astronauts use to grow crops. So far, the International Space Station has successfully grown dwarf wheat and radishes.
Growing plants onboard the International Space Station has multiple benefits, says Robert Morrow, principal scientist for SNC’s Propulsion and Environment Systems, including improving air quality. It could also give astronauts more time to switch oxygen tanks in case of an emergency. Most importantly, vegetables are a great source of vitamins and nutrients, which are essential for long-term missions.

There are many mysteries surrounding the planet Neptune, but one in particular has sparked interest in the scientific community: a storm whose actions are still puzzling scientists.
A storm was first observed in 1989 by the Voyager 2 (currently the only spacecraft to reach Neptune). This storm had a companion storm that was smaller and was nicknamed “Scooter.” When the Hubble telescope was launched in 1993, scientists were once again able to see storms on Neptune. In 2018 another storm nicknamed “Dark Spot” was spotted traveling towards the equator of Neptune, but then in January of 2020 it changed directions heading north. At the same time, a smaller companion storm nicknamed “Dark Spot Jr.” was observed.
The Dark Spot is 4,600 miles across, which is larger than the Atlantic Ocean. These storms on Neptune are observed to last 2-5 years, which is short in comparison to storms on other distant planets. Scientists find Neptune’s storms hard to study due to their relatively short duration.

Recently, Nokia, a Finnish telecommunications and consumer electronics company, announced that they are developing the Moon’s first 4G cell network. The network will assist NASA’s Artemis team in their upcoming mission. Artemis is a new lunar exploration program that will put people on the Moon for the first time since 1970.
NASA has awarded a combined amount of $370 million to 14 different companies to develop technologies for the Artemis launch. This includes Nokia, whose US Bell Labs division is in charge of creating a 4G network to be deployed in a lunar landing in 2022. This network will help the astronauts with tasks such as data transmission, controlling lunar rovers, real time navigation, and lunar geography.
NASA’s goal is to build a lunar base and sustain human life on the Moon by 2028. Nokia’s chief technology officer, Marcus Weldon, says that the 4G network is the first step to achieving this. “Reliable, resilient and high-capacity communications networks will be key to supporting sustainable human presence on the lunar surface.”

On November 15, 2020, NASA made history by launching the first full flight in partnership with a private American space company, SpaceX, from Kennedy Space Center in Florida. The Falcon 9 rocket and Crew Dragon capsule carried three American astronauts and one Japanese astronaut to the International Space Station (ISS).
The Falcon 9 rocket and Crew Dragon capsule were built by SpaceX, an aerospace manufacturing company founded by Elon Musk. NASA has been paying Russia to fly American astronauts into space via the Russian Soyuz capsule since 2011. Since the Crew Dragon is able to carry one more passenger than the Russian capsule, seven astronauts will be able to stay on the ISS.
The Crew Dragon will remain attach to the ISS until its return voyage to Earth. The ISS currently has only enough space for six astronauts to sleep, so the Crew Dragon will be used as a temporary bunk for the seventh astronaut.

NASA scientists have now concluded that more water exists on the moon than previously believed. Using a satellite orbiting the moon, NASA has confirmed that there is water on both the sunlit and shadowed parts of the moon.
This information may help advance future lunar missions. “If we're right, water is going to be more accessible for drinking water, for rocket fuel, everything that NASA needs water for” said scientist Paul Hayne, who led the study.
The study was conducted using an aircraft called SOFIA (Stratospheric Observatory for Infrared Astronomy), which carries a 2.7 meter telescope.

Did you know that a space station is similar to a house? It has showers, kitchens, and living areas. But it also has a control center where astronauts , or cosmonauts as they’re known in Russia, can work.
The International Space Station (ISS) is the largest space station that took a team effort to build. Sixteen countries contributed to the effort. Specifically, it took the cooperation of the U.S., Russia, Japan, Canada, Brazil, and 11 European countries. The station was built on Earth and sent piece by piece into space and put together by the shuttle’s robot arms.

In 1969, Neil Armstrong was the first man to reach the Moon. In 1983, Sally Ride was the first American woman to walk in space. And now through Artemis, a new lunar exploration program, there are plans to send the first woman to the Moon as soon as 2024.
NASA administrator Jim Bridenstine told CNN that the first female astronaut to walk on the moon will be someone “who has been proven, somebody who has flown, somebody who has been on the International Space Station already” and someone who is currently in the astronaut corps. Bridenstine wants to release the identities of the team soon, at least two years before the mission, hoping it will be a beacon of inspiration for girls all over the world who are witnessing this iconic time in history.
Planning for the Future at Yerkes Observatory
by Makya Rodriguez, age 14
The world's largest refracting telescope is located at Yerkes Observatory in Williams Bay on Lake Geneva, Wisconsin. It was used by many well-known space researchers in the past. The facility was recently donated to the Yerkes Future Foundation by the University of Chicago. The foundation has plans to refurbish the 123-year-old facility, and hope to have it open to the public as soon as spring 2021. The many refurbishments will improve research capabilities and the very structure itself.
The observatory possesses six domes, the largest being 90 feet tall. The property contains laboratories and a vault with images of stars, planets, and remote solar systems. These archives have been harvested by many great minds over the years. The property also offers two houses that will be renovated for visiting scholars. The $20 million non-profit effort hopes to keep the research facility viable for another century, serving both public and private events.
Several famed individuals who have made great contributions to the field of science have walked the observatory's floors. Albert Einstein walked the floors in 1921, as did Nobel Prize winner Subrahmanyan Chandrasekhar, a famed space scientist, more recently, to name a few. The 73-foot diameter floor they walked on is actually a 37.5-ton elevator that goes up to the refracting telescope. Once at the refracting telescope, researchers have the ability to investigate the universe from afar.
European Space Agency Solar Orbiter Makes History with Close Solar Approach
by Moises A. Hernandez, age 15
Space science took a new step forward as the European Space Agency (ESA)’s Solar Orbiter traveled closer to the sun than any other spacecraft in history. On Monday, June 15, 2020, the Solar Orbiter reached 48 million miles from the sun’s surface, making its first close pass of the sun. The Solar Orbiter launched from Cape Canaveral, Florida, at 11:03 p.m. EST on Sunday, February 9, 2020, as part of a joint mission between the National Aeronautics and Space Administration (NASA) and the ESA. This is the first mission in this global space collaboration.
Being the first of its kind, this mission will produce images of the north and south poles of the sun using six telescopes on board to capture the spacecraft’s view. The importance of having a visual understanding of the sun’s poles is that it can provide more information about the sun’s powerful magnetic fields. These magnetic fields affect Earth in numerous ways, including space weather, which affects networked systems like the Global Positioning System (GPS), communications, and astronauts on the International Space Station (ISS). To take these images, the Solar Orbiter must be at a distance close to the sun.
The spacecraft’s first perihelion, the point nearest to the sun in the path of an orbiting celestial body (such as a planet), was about half the distance between the Earth and the sun. Daniel Müller, the ESA’s Solar Orbiter project scientist, reported the closest approach of the probe to be around 3:35 a.m. EST. Since then, the spacecraft advanced to the “cruise” phase of its mission, in which it will travel even closer to the sun’s surface--around 26 million miles closer than Mercury. This distance will allow the Solar Orbiter to make never-before-seen observations of the sun that would be impossible from a farther distance.
Our Solar System May Be Stranger than We Thought
by Vanessa Shell, age 15
Lauren Weiss, a Parrent Postdoctoral Research Fellow at the Institute for Astronomy at the University of Hawai’i, Manoa, encountered an interesting pattern among the planetary systems newly discovered by the Kepler spacecraft. But, our solar system does not adhere to the pattern she discovered. Weiss’ research raised the question of whether our group of planets is an outlier, or whether her discoveries were simply based on coincidences.
The Kepler--named after the 17th century German astronomer--is a NASA spacecraft that launched in 2009 with the singular purpose of finding new planets in our universe. Since then, over 400 multi-planet systems have been found. The Kepler has spotted these other solar systems by way of continuously measuring the brightness of other stars and waiting for the light coming from the star to dim slightly, which signifies a planet passing in transit. Using Kepler’s findings, Weiss was found that planets in the same system tended to be the same size. Giving an example, she said, “If one planet is 1.5 times the radius of Earth, the other planets in the system are very likely to be 1.5 times the radius of Earth, plus or minus a little bit.”
The whole population of exoplanets discovered ranges from one fourth of the size of Earth to twenty times the size of our planet. With this in mind, Weiss stated, “Despite the wide range of possible sizes, planets tend to be the size of their neighbors.” These solar systems with like-sized planets were soon dubbed “peas in a pod” by the group studying them. Weiss decided then to develop an experiment to test the “peas in a pod” theory, asking the question, “Could some sort of bias in Kepler’s method of finding planets--which favors the detection of large planets close their stars--contrive to make the planets in each of my imaginary systems appear to fit the pattern?”
What Would Happen if the Earth Spun Faster?
by Eowyn Gomez Cruz, age 15
Have you ever wondered why we never feel the Earth spin? Do you wonder if the Earth ever speeds up or slows down?
The Earth spins fastest at its waistline, the equator, so how fast the Earth spins in a certain place depends on the location and distance from the equator. A spot on the equator travels farther in 24 hours than other places on the Earth do. For example, Chicago spins at approximately only 750 mph, while the equator spins at 1037 mph.
Speeding up Earth's rotation by 1 mph would cause the water from the poles to gather around the equator, making sea levels rise there. It may take some time for people to notice the gradual change. That one extra mile would also affect our satellites, which would then interfere with our TV broadcasting and even our military intelligence. Many of those satellites would have to be replaced.
NASA Astronauts Describe 'The Moment When it all Changed'
by Zainab Yahiaoui, age 15
During research voyages in space, astronauts have the opportunity to see our planet Earth from many miles away. Countless others remain hopeful to someday have the same experience. Six astronauts, who had the chance to go into space, described their individual experiences during their time away from the planet. Chris Hadfield, Jerry Linenger, Nicole Scott, Mae Jemison, Leland Melvin, and Mike Massimino have all spent at least a week in space, if not longer. They each had different and distinct moments in space when their perspectives of the world changed, a shift which is called the “overview effect.”
One of the astronauts, Chris Hadfield, spent 166 days in space. He said his change of perspective happened quickly and that his emotions crept up on him while he was not prepared. Hadfield said in space, one has to take a lot of pictures because everyone is so busy working, there is not enough time to look outside. His “aha” moment occurred when he was taking a picture of Pakistan from the spaceship; he referred to the country as “us” instead of “them,” despite him not being from Pakistan. This event made Hadfield realize that humans are all on the earth together and are not truly divided by countries of origin.
Laser Sails Could Reach Alpha Centauri in 20 Years
by Devika Pal, age 14
Using new technology created by researchers at the Rochester Institute of Technology in New York, a spacecraft would be able to be launched to the closest star, Alpha Centauri, which is 437 light-years away.
Chemical reactions are used to propel standard rockets. However, the bigger the rocket is, the more propellant it needs, making the spacecraft heavy and inefficient. For long trips, this is a waste of money and resources. In 1977, NASA launched the Voyager 1 Spacecraft into interstellar space, which it reached 25 years later. If Voyager 1 had been launched to Alpha Centauri, it would have arrived there in 75,000 years.
Is Titan the Most Earth-Like Body in the Solar System?
by Hanna Eyobed, age 15
The thought of living on another planet may seem like something out of a science fiction book. But what if we could sustainably live on another planet that contains similar qualities and could host life, like Earth? What if I told you a small moon revolving around Saturn could do just that?
Titan is the only place in our solar system that has characteristics most like Earth’s. Water in the atmosphere shelters Earth from galactic cosmic rays (GCRs). These rays are energetic particles that, if it weren’t for Earth’s atmosphere, would make the Earth uninhabitable. GCRs can cause cancer because of their radiation. Exposing mice to GCR radiation results in brain damage and a loss of simple activity within the mice, according to a study performed by Vipan K. Prihar and colleagues in Science Advances. The methane and ethane in the atmosphere of Titan is similar to the water in the Earth’s atmosphere, and could potentially allow Titan to maintain human life.
Space: Our New Habitat
by Sandy Flores, age 13
Did you know that one day Earth may no longer be habitable?
If this becomes a reality, people will have to learn how to adapt to life in outer space. Scientists are envisioning what is needed to live in space. Humans will have to learn how to do this since Earth will no longer have the capacity to hold them. Most of humanity would die if this happened. The survivors who remain alive will have to learn how to adapt to life in a capsule.
NASA's Great Space Mission, Cassini
by Makya Rodriguez, age 14
One of NASA’s greatest space missions was the launching of the Cassini spacecraft. Starting on June 30, 2004 and ending on September 15, 2017, the Cassini spacecraft overcame several challenges in order to enter Saturn’s atmosphere. It traveled a complicated path to gain speed from other planets’ gravity. The cost of the mission totaled approximately 3.26 billion dollars.
Cassini settled in Saturn’s orbit on July 1, 2004. Its main mission was to find more of Saturn’s moons and gather more information about Saturn’s rings. Cassini’s most important task was to release the Huygen Lander on Titan, Saturn’s largest moon. The Huygen Lander went though a mysterious haze and landed on June 14, 2005. Researchers examined pictures sent back of the rock fields, and discovered more about its climate.
The Massive Meteor Explosion that Scientists Almost Missed
by Kara Nichols, age 16
In 2018, a meteor, crossed the sky before exploding with ten times the power of an atomic bomb.
On December 18th 2018, a space rock going 71,500 miles per hour passed into the earth’s atmosphere before exploding. The explosion occurred between Russia and Alaska right over the Bering Sea. The meteor was 16 miles above the ocean and it discharged 173 kilotons of energy after the explosion.
Space Economy is Threatened by Orbiting Junkyard
by Mariama Bah, age 13
When you see images of Earth from outer space, you don’t notice the 500,000 pieces of debris floating around in low-earth orbit. All of that debris is affecting the satellite business, threatening the future commercialization of space, and jeopardizing the growth of the space economy.
The space economy includes both public and private sector developers of space-enabled products and services. In the space economy, there are three main industries. One industry is focused more on Earth, which includes things that deliver something to space, or something that is in space, but benefits the people on Earth. Another industry is focused on space itself, including space travel and tourism in space. The last main industry is under development and includes the process of mining asteroids and exporting resources from space. Even though the industries are developing, the space economy is already helping businesses on Earth.
Astronomers Discover Bizarre “Whiplash” Planet
by Leilani McNeal, age 15
Astronomers are in shock as they have recently discovered a foreign planet that is three times bigger than Jupiter. Planet HR 5183 b has quickly earned a notorious reputation because it has a strong, elliptical orbit — so strong that if it orbited in our solar system, it would completely shift the orbits of our outermost planets.
“A wacky object,” is how a California Institute of Technology graduate student Sarah Blunt described HR 5183 b. The wackiness could remind one of either an amusement park ride or a rocket ship where the object slows down and speeds up unpredictably. Since the exoplanet’s ellipse is much more elongated than other planets, scientists began to question the origin of its abnormal orbit. “It seems like every time we think we’ve found the weirdest solar system, something else totally strange is discovered,” Blunt stated in an email.

Throw an object, like a ball, into space from Earth at an approximate speed of 25,000 miles per hour. The object would have enough momentum to escape Earth's gravity and reach outer space. This speed is scientifically referred to as an escape velocity and differs for all gravitational fields. The more mass a planet or star has, the stronger its gravitational field, thus the greater its escape velocity. Black holes' masses are so large that their theoretical escape velocity is greater than the speed of light, making them appear colorless or black. [read more...]
The sun’s magnetic field, referred to as the heliosphere, spans the entire solar system. It extends past Pluto and reaches out to the Voyager probes that are sent into interstellar space. The direction of the sun's magnetic field, known as its polarity, reverses roughly every 11 years. During a magnetic field reversal of the sun, the magnetic field weakens, becomes neutral, and then emerges again with the opposite polarity. [read more...]
A little over four and a half billion years ago, a solid mass called the Moon was formed. The Moon has given rise to many myths, legends, and mysteries.

Although there is a difference between asteroids and meteoroids, both are solid bodies in space. A meteoroid is a small piece of space debris, usually made up of rock or iron. This meteoroid is re-labeled a meteorite when it enters a planet’s atmosphere. An asteroid is described as a larger, solid body of rock that orbits around a star. [read more...]
The mystery of Saturn’s rings has puzzled humans for centuries. During the 20th century, many astronomers theorized that Saturn’s moons had years ago collided with each other, or with an asteroid, leaving behind debris. This debris then formed Saturn’s characteristic rings. If this hypothesis were true, however, rock particles like those that make up Saturn’s moons would be found in its rings. These moons are about half rock and half ice. More recently, scientists discovered that the rings are 95 percent made of ice. In other words, there is much less rock in the rings than in the moons. [read more...]
About 4.5 billion years ago, a Mars-sized asteroid collided into the newly molten Earth. The powerful impact threw scattered debris into space. Over millions of years this rubble formed a roughly-shaped sphere that started to orbit the Earth. Today we call this sphere Earth’s moon. [read more...]
