  1. 5. An instrument that gathers and magnifies light to observe distant objects in space, including stars, planets, and galaxies.
  2. 6. The natural satellite that orbits around the Earth and reflects sunlight, causing different phases.
  3. 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.
  4. 8. A luminous ball of gas that produces its own light and heat through nuclear reactions, like our Sun.
  5. 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.
  6. 11. The star at the center of our solar system that provides light and heat to the planets.
  7. 12. Hole: A region in space with extremely strong gravitational forces that nothing, not even light, can escape from.
  8. 13. System: A system that consists of the Sun, planets, moons, asteroids, comets, and other celestial bodies that orbit the Sun.
  9. 14. Our home planet, the third planet from the Sun, where we live and where various ecosystems exist.

  1. 1. A person trained to travel and work in space. Astronauts conduct experiments, repair satellites, and explore other celestial bodies.
  2. 2. A large celestial body that orbits a star, such as the Sun. There are eight planets in our solar system, including Earth.
  3. 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. 4. Vehicles designed to travel and operate in outer space, such as rockets, shuttles, and satellites.
  5. 9. A vast cloud of gas and dust in space. Nebulas can be regions where new stars form or remnants of exploded stars.
  6. 11. Station: A large structure in space where astronauts live and conduct scientific research. The International Space Station (ISS) is a well-known example.
