Universe

3. A glowing celestial object made up of hot gases, which produces heat and light through nuclear reactions happening at its core.
4. A small celestial object that enters the Earth's atmosphere and burns up, creating a streak of light in the sky, also known as a shooting star.
5. A large celestial body that orbits around a star, like our Earth, with its own atmosphere and capable of supporting life.
7. A rocky object smaller than a planet that orbits around the Sun, typically found in the asteroid belt located between Mars and Jupiter.
8. Relating to or associated with the Moon, such as lunar eclipses, lunar craters, or lunar missions.
9. A gigantic collection of stars, planets, gas, and dust held together by gravity, with billions of galaxies existing in the vastness of the universe.
10. An object launched into space that orbits around a planet or another celestial body, used for communication, weather observation, and more.
12. A cosmic object made up of ice, dust, and rock, characterized by a glowing coma and a tail when it approaches the Sun.
13. Hole A region in space with extremely strong gravity that nothing, not even light, can escape from, making it appear black and invisible.

1. The force that attracts objects toward each other, keeping planets in orbit around the Sun and giving weight to physical objects on Earth.
2. A person who travels and works in space, usually as a member of a spacecraft crew, conducting scientific experiments and exploring the universe.
3. System A system consisting of a star (Sun) and the celestial objects, including planets, moons, asteroids, and comets, that orbit around it.
4. Rover A robotic vehicle sent to explore the surface of Mars, collecting data and images to study the planet's geology and potential for supporting life.
6. An instrument used to observe distant objects in space, allowing astronomers to see faraway galaxies, stars, and planets in more detail.
10. Shuttle A reusable spacecraft used by NASA to carry astronauts and cargo into space, with the ability to launch like a rocket and land like an airplane.
11. A large cloud of gas and dust in space, often brightly colored, where new stars are born or where old stars release their outer layers.
