Across
- 5. An instrument that gathers and magnifies light to observe distant objects in space, including stars, planets, and galaxies.
- 6. The natural satellite that orbits around the Earth and reflects sunlight, causing different phases.
- 7. A celestial object composed of ice, dust, and gas that orbits the Sun in an elongated shape. When close to the Sun, comets develop a glowing coma and tail.
- 8. A luminous ball of gas that produces its own light and heat through nuclear reactions, like our Sun.
- 10. A vast collection of stars, dust, and gas held together by gravity. The Milky Way is the galaxy where our solar system is located.
- 11. The star at the center of our solar system that provides light and heat to the planets.
- 12. Hole: A region in space with extremely strong gravitational forces that nothing, not even light, can escape from.
- 13. System: A system that consists of the Sun, planets, moons, asteroids, comets, and other celestial bodies that orbit the Sun.
- 14. Our home planet, the third planet from the Sun, where we live and where various ecosystems exist.
Down
- 1. A person trained to travel and work in space. Astronauts conduct experiments, repair satellites, and explore other celestial bodies.
- 2. A large celestial body that orbits a star, such as the Sun. There are eight planets in our solar system, including Earth.
- 3. A small rocky or metallic object that travels through space. When it enters Earth's atmosphere and burns up, it is called a meteor.
- 4. Vehicles designed to travel and operate in outer space, such as rockets, shuttles, and satellites.
- 9. A vast cloud of gas and dust in space. Nebulas can be regions where new stars form or remnants of exploded stars.
- 11. Station: A large structure in space where astronauts live and conduct scientific research. The International Space Station (ISS) is a well-known example.
