Ancient Astronomers Thought
Mars Was Filled With Life
by Savanah Shadof, age 13
Eons ago, ancient civilizations noticed a reddish and extremely bright star in the sky. They named this star Mars. Over the course of hundreds of years, humans learned that this star is actually a planet. Space scientists discovered that the planet's days (called sol's), seasons, and possible vegetation are all similar to Earth's.
Days on Mars are like any Earth day in its routine. The sun rises, climbs into the sky, and sets on both planets. In contrast to Earth?s 24-hour day, however, Mars has a 24 hour and 37 minute day. This difference in daytime adds up fast. The Martian year is nearly double the Earth year. In fact, a whopping 687 Earth days is equal to one year on Mars. [Read More]
Eight-Legged Creepy Crawlers Hunt to Survive
by Tyrone Austin, age 12
What crawls on eight legs and hunts to stay alive? Spiders, scorpions, ticks, and mites all fit this description.
Most—not all—spiders make webs. Those that do produce a liquid silk from a gland in their stomachs. These spiders have special body parts called spinnerets that pull out the silk. Then, they use their legs to turn the liquid silk into the webs in which they catch their prey. [Read More]
Jupiter is the Largest
Planet in the Solar System
by Mario Rea-Garcia, age 12
Jupiter is the largest planet in our solar system; in fact, 11 earths would barely stretch over the diameter of Jupiter. For centuries, scientists have been interested in this massive planet and its moons.
In October of 1989, a spacecraft names "The Galileo" was launched to Jupiter. When it finally reached Jupiter's orbit in 1995. The spacecraft began a 22-month study of Jupiter's moons. Unfortunately, scientists were not able to receive information from The Galileo until later due to problems with the spacecraft's antenna. [Read More]
What Makes the Milky Way the Milky Way?
by Janavia Calmese, age 12
Billions of galaxies exist across the universe. Our home, Planet Earth, is located in a galaxy called the Milky Way.
Many of the stars in the Milky Way galaxy are packed in its nucleus, or central region. Flat, slim circles that contain many stars envelop the nucleus. Made up of dust and gas clouds, these stars are organized in a spiral pattern that measures 100,000 light years across. [Read More]
