In one word, describe the feeling of fascination that comes from learning about space?
"Represent data in graphical displays to reveal patterns of daily changes in length and direction of shadows,
day and night, and the seasonal appearance of some stars in the night sky."
The universe is the collection of all galaxies, stars, and planets. We live in a single galaxy, the Milky Way, which contains billions of stars. There are billions of galaxies in the universe, and each contains billions of stars!
Exploring the Universe
Solar System: The solar system is made up of all the planets that orbit our Sun. In addition to planets, the solar system also consists of moons, comets, asteroids, minor planets, and dust and gas. Galaxy: A galaxy is a massive group of stars, gas, dust, and dark matter bound together by gravity. Our own solar system is part of the Milky Way Galaxy. Astronaut: An astronaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft.
The solar system is roughly 4.6 billion years old, which is almost as old as the universe itself. The average distance between the sun and the Earth is 93 million miles, which is equivalent to 8 light-minutes. The ISS orbits the earth once every 90 minutes, travelling at a speed of 17,500 miles per hour.

Space is the area outside of Earth's atmosphere. It's full of stars, planets, and other objects like comets and asteroids. Scientists use telescopes to learn more about what's out there.
Solar System: A system of planets, moons, asteroids, comets and other objects that orbit around a star, such as our Sun. Gravity: A force of attraction between two masses, or objects, that is proportional to the product of their masses and inversely proportional to the square of the distance between them. Space Exploration: The study of the universe outside of the Earth's atmosphere by means of spacecraft and robotic probes.
The temperature on the surface of the sun is estimated to be around 5,505 degrees Celsius. The gas giants (Jupiter, Saturn, Uranus, and Neptune) are not made up of solid matter, but rather hydrogen and helium in gaseous form. The Hubble Space Telescope orbits the Earth at a speed of 5 miles per second.
