space

1. Hole A region in space with extremely strong gravity that nothing, not even light, can escape from. Black holes form when massive stars collapse.
4. A celestial object made up of ice, dust, and gas that orbits the Sun. When a comet gets close to the Sun, it develops a glowing coma and a tail.
5. A small rock or particle in space. When a meteoroid enters Earth's atmosphere and burns up, it is called a meteor.
7. A term used in some countries for an astronaut or a person who travels and works in space. It is commonly used in Russian-speaking countries.
8. An instrument used to observe distant objects in space. Telescopes gather and focus light, allowing us to see celestial bodies more clearly.
12. A person who travels and works in space. Astronauts undergo extensive training to be able to live and work in microgravity conditions.
13. A cloud of gas and dust in space. Nebulas are often the birthplaces of stars and can have beautiful, colorful shapes and patterns.

2. A scientist who studies celestial objects such as stars, planets, galaxies, and other phenomena in the universe.
3. A vehicle that is propelled by engines and carries spacecraft into space. Rockets provide the necessary thrust to overcome Earth's gravity.
6. A large celestial body that orbits around a star. Planets are round and do not produce their own light but reflect the light of the star they orbit.
9. The curved path followed by an object, such as a planet or a satellite, as it revolves around another object, usually a star.
10. System A system consisting of a star (the Sun) and the celestial objects that orbit around it, including planets, moons, asteroids, and comets.
11. A massive collection of stars, dust, and gas held together by gravity. Galaxies can be spiral, elliptical, or irregular in shape.
