A few billion years ago, in a galaxy not so far, far away, before humans even existed, the universe was created. Scientists posit that the universe was formed about 13 billion years ago. Imagine a black, empty void followed by a flaming ball of dust and debris forming our universe; this theory is called the “Big Bang.” [read more...]
Two of Jupiter’s 63 moons are thought to be “twins.” The two moons were formed at the same time and are the same shape and size, but they are far from identical. [read more...]
Stars are fiery balls of hot gas that are constantly burning. Inside of each star, atoms of gas come together and create a nuclear reaction. This makes them rise in temperature to millions of degrees, creating a star's glow. As these stars shine, they release light, heat, radio waves, and radiation. But, when their nuclear fuel is used up, they no longer glow. [read more...]
Since Apollo 17, human beings have not traveled more than 380 miles above the Earth's surface. But later this year, that will change. NASA is currently working to build a capsule designed to send astronauts more than 3,600 miles into deep space. [read more...]
The moon and stars are not the Earth’s only natural nightlights. Comets, asteroids, and meteors travel through space and shine brightly, too. It is the distinct ways in which comets, asteroids, and meteors move that make them each unique. [read more...]
While they might all look similar from Earth, stars actually differ in size, color, and temperature. However, all stars are born in and end the same way. [read more...]
A fantastic discovery was made one night in 1844 by German astronomer, Friedrich Wilhelm Bassel. Bassel discovered a dark and mysterious force in the universe, now known as the black hole. [read more...]
From Copernicus to Neil deGrasse Tyson, it seems as though humans have always been interested in going to space. The idea of space exploration began in 1957, with the launch of the first artificial satellite. [read more...]
Titan, Saturn’s largest moon, was discovered in 1655 by Dutch astronomer, Christiaan Huygens. With a simple homemade telescope, he alerted the world to one of many secrets of the universe. [read more...]
Billions of years ago there was a boom. According to scientific theory, that boom was the start of Universe. This idea is called the “Big Bang Theory.” [read more...]
Mercury is our solar system’s innermost planet. It is a planet we all have heard about, but don’t know much about. Previously, scientists did not pay much attention to Mercury. But, in 2004, our view of Mercury changed when NASA sent a spacecraft called the Messenger to explore the mysterious planet. first paragraph [read more...]
Did you know that the two nearest planets to Earth are Venus and Mars? Every planet circles the sun in a different amount of time, which is called a planet’s year. Venus takes 225 days to complete a year, Mars takes 687 days, and Earth takes 365 days. [read more...]
