Category: Outer Space

Outer Space refers to the vast, seemingly infinite expanse that exists beyond Earth’s atmosphere. It is a near-perfect vacuum that begins approximately 100 kilometers (62 miles) above sea level, where atmospheric pressure becomes negligible. Outer Space is characterized by the absence of air and the presence of celestial bodies, such as stars, planets, moons, asteroids, and comets, as well as cosmic dust and radiation.

In the context of astronomy and space exploration, Outer Space is the region where phenomena such as black holes, galaxies, and nebulae can be found. It is also the environment in which human-made objects, such as satellites and spacecraft, operate. The study of Outer Space is essential for understanding the universe’s origins, structure, and eventual fate, as well as for practical applications such as telecommunications, weather monitoring, and navigation. Additionally, Outer Space is governed by international treaties and agreements that outline the peaceful use and exploration of celestial bodies.
