Space and Space Exploration

4. A vast system of stars, stellar remnants, interstellar gas, and dust bound together by gravity, forming a distinct structure in space.
5. A cloud of gas and dust in space, often illuminated by nearby stars or other celestial phenomena.
7. An optical instrument that gathers and magnifies light to observe distant celestial objects, such as stars and planets.
9. Tourism Commercial travel to space for recreational, leisure, or adventure purposes, allowing private individuals to experience spaceflight.
11. Hole A region in space where gravity is so strong that nothing, not even light, can escape its gravitational pull.
12. A planet that orbits a star outside our solar system, potentially hosting conditions for life.
14. Shuttle A reusable spacecraft designed for human spaceflight, capable of carrying astronauts and cargo into space.

1. Exploration The exploration of the Moon's surface using robotic spacecraft or crewed missions, studying its geology and composition.
2. Station A large spacecraft in orbit around the Earth, serving as a habitable artificial satellite for scientific research and exploration.
3. An object placed in orbit around a celestial body, often used for communication, observation, or navigation.
6. A vehicle that uses controlled explosions of propellant to generate thrust and propel itself into space.
8. An activity where astronauts leave the confines of their spacecraft to work in open space, often tethered to the vehicle.
9. Probe An unmanned spacecraft designed to explore the solar system and beyond, gathering data and transmitting it back to Earth.
10. A celestial object consisting of ice, dust, and gases that orbit the sun, producing a bright, glowing tail when near it.
13. A person trained to travel and work in space, conducting experiments and tasks in a spacecraft or space station.
