- 3. Interstellar refers to the space between stars. It represents the vast distances and possibilities for exploration and discovery beyond our solar system.
- 6. The universe is the vast expanse that contains all matter, energy, planets, stars, galaxies, and everything in existence. It is constantly expanding and full of mysteries.
- 7. A comet is a celestial object made of ice, dust, and gas. As it orbits the sun, it develops a glowing coma and sometimes a tail, creating a beautiful spectacle in the night sky.
- 8. hole A black hole is a region in space where gravity is so strong that nothing, not even light, can escape its pull. It is formed from the remnants of massive collapsed stars.
- 10. A galaxy is a vast system of stars, planets, gas, and dust held together by gravity. It can contain billions of stars and is often shaped like a spiral or an elliptical.
- 11. A satellite is an object that orbits a planet, moon, or other celestial body. It can be natural, like a moon, or artificial, like a spacecraft sent from Earth.
- 13. A telescope is an instrument used to observe distant objects in space. It collects and magnifies light, allowing astronomers to study stars, planets, and galaxies.
- 14. A supernova is a powerful and explosive event that occurs at the end of a massive star's life. It releases a tremendous amount of energy and can briefly outshine entire galaxies.
Down
- 1. A star is a luminous ball of gas that emits light and heat. It is held together by its own gravity and produces energy through nuclear fusion.
- 2. A meteor is a small celestial body that enters the Earth's atmosphere and burns up, producing a streak of light in the sky. It is also known as a shooting star.
- 4. A spacecraft is a vehicle designed for travel or operation in outer space. It can be manned or unmanned and is used for exploration, research, and communication.
- 5. A planet is a large celestial body that orbits a star. It is round and has cleared its orbit of other debris. Our solar system has eight planets, including Earth.
- 9. An asteroid is a rocky object that orbits the sun. It is smaller than a planet and larger than a meteoroid. Asteroids can be found throughout the solar system.
- 10. Gravity is a force that pulls objects toward each other. It keeps planets in orbit around stars, moons around planets, and plays a crucial role in shaping the structure of the universe.
- 11. system A solar system is a collection of planets, moons, asteroids, comets, and other celestial objects that orbit around a star, such as our Sun.
- 12. A nebula is a cloud of gas and dust in space. It often appears as a colorful and ethereal formation, where stars are born and new worlds are formed.
