Universes

7. Galaxy A galaxy that is very far away from us. It's similar to our Milky Way Galaxy and has billions of stars in it.
8. A group of stars that form a pattern in the sky. People have named constellations after animals, mythological creatures, and other things.
10. A bright streak of light that you see in the sky when a small space rock, called a meteoroid, burns up in the Earth's atmosphere.
11. System The place where we live! It includes the Sun, planets like Earth and Mars, and other objects that orbit the Sun.
12. A gigantic collection of stars, gas, and dust held together by gravity. There are many galaxies in the universe.
13. A space object made of ice, dust, and gas that moves around the Sun. When it gets closer to the Sun, it develops a tail.
14. A planet that is outside our Solar System and orbits a star. Scientists search for exoplanets to find places with life.
15. A big ball of hot, glowing gas that shines brightly in the night sky. Some stars are much bigger and hotter than others.

1. A huge explosion that happens when a massive star reaches the end of its life. It's an incredibly bright and powerful event.
2. A rocky object that orbits the Sun. Some asteroids are big like planets, while others are small like pebbles.
3. The big empty area beyond our planet. It's full of stars, planets, and other exciting things to explore.
4. Hole A place in space where gravity is extremely strong. It pulls everything, even light, into it and nothing can escape.
5. Way Galaxy Our home in space! It's a huge collection of stars, planets, and other objects held together by gravity.
6. A force that pulls objects toward each other. It keeps us on the ground and holds the planets and stars in place.
9. A cloud of gas and dust in space. Nebulas can be different colors and shapes, and they are where new stars are born.
11. A man-made object that orbits around a planet or another object in space. Satellites are used for communication and observation.
