Astronomy is the science of the universe, stars, planets, galaxies, and solar systems. Our solar system has a sun, a massive fireball that burns hydrogen and helium. Nuclear Fission is the process of separating atoms, splitting particles that release energy and cause other particles to split. Nuclear Fusion is the process of combining atoms, producing energy and causing other particles to combine. Solar flares are massive waves of fire that the sun periodically produces. A solar eclipse results when the moon, a satellite in orbit around Earth, moves between the sun and Earth, causing the moon to cast a shadow on Earth. A lunar eclipse results when the earth moves between the sun and the moon, causing Earth to cast a shadow on the moon. There are nine planets and an asteroid belt that orbit the sun in our solar system. These planets are Mercury, Venus, Earth, Mars, the Asteroid Belt - perhaps a planet that broke apart or exploded - Jupiter, Saturn, Uranus, Neptune, and Pluto. Sir Isaac Newton explained the laws of motion in the universe. Any object in motion will remain in motion unless acted upon by a force. Any object at rest will remain at rest unless acted upon by a force. Every action has an equal and opposite reaction. Albert Einstein explained that energy equals mass multiplied by the speed of light squared, E = mc^2. Astronomers use telescopes to study distant objects. Telescopes magnify, collect, and reflect light, allowing images of far away objects to be seen. Remote sensing uses radar, sonic waves, radio waves, and electronic technology to observe distant objects. Our galaxy is the Mily Way Galaxy. The Milky Way Galaxy is a disk shaped galaxy. The Milky Way Galaxy is one of several galaxies in a group of galaxies known as the Local Group. Our planet, Earth, supports life. SETI is the Search For Extraterrestrial Intelligence, life on far away planets. NASA is the National Astrophysics And Space Administration. NASA studies planets, stars, and galaxies across the universe. -DuskyRiver
