What Is SPACE?

 

Space, also known as outer space, is the vast, seemingly infinite expanse that exists beyond Earth's atmosphere. It is not completely empty but rather contains various celestial objects such as stars, planets, moons, asteroids, comets, galaxies, and the interstellar medium. Space is characterized by extremely low pressure and density, making it different from the atmosphere of planets.

In space, there is no air, which means there is no atmosphere to scatter light or conduct sound. The absence of atmosphere also leads to extreme temperature variations. Space is governed by the laws of physics, including gravity, which plays a crucial role in the formation and movement of celestial bodies.

Exploration of space has been a significant endeavor for scientific research and discovery, involving both manned and unmanned missions. The study of space contributes to our understanding of the origins, evolution, and dynamics of the universe.
