Outer Space

Outer space is the vast, seemingly infinite expanse beyond Earth's atmosphere where planets, stars, galaxies, and other celestial bodies exist. It is characterized by an almost complete vacuum, with very few particles, which means there is very little matter or air to support life as we know it. Space is governed by the laws of physics, such as gravity and electromagnetism. It is the setting for astronomical phenomena, space exploration, and the origins of the universe. Despite its emptiness, space contains complex structures and holds critical clues about the universe's history and composition.
