Space
Space is the vast, seemingly infinite expanse that exists beyond the Earth's atmosphere. It is a subject of great interest and curiosity for scientists, astronomers, and the general public. The study of space encompasses a wide range of topics including the structure of the universe, celestial bodies such as stars and planets, and the exploration of outer space.
Key Concepts in Space
- Universe: The universe is everything that exists, including all matter, energy, planets, stars, galaxies, and the space between them.
- Galaxies: These are vast systems of stars, gas, and dust bound together by gravity. The Milky Way is the galaxy to which our solar system belongs.
- Stars: These are massive, luminous spheres of plasma held together by gravity. They are the fundamental building blocks of galaxies.
- Planets: These are celestial bodies that orbit around a star. They vary in size, composition, and atmosphere.
- Space Exploration: This involves the investigation of outer space using manned and unmanned spacecraft. It aims to learn more about the universe and potentially establish a human presence beyond Earth.
