The vast, three-dimensional void that envelops everything in the cosmos is called space. It is referred to as the area beyond the Earth's atmosphere where gravitation is weak or nonexistent, there is no air or other atmospheric gases, and there is no atmosphere. The internal and outer sun system, interstellar space, and intergalactic space are just a few of the different regions that are typically divided up into according to how close they are to Earth.
There are many different celestial objects in the universe, including stars, planets, asteroids, meteors, and more. These celestial bodies are held together by gravity and engage with one another using a variety of physical processes, including collisions, gravitational interactions, and electromagnetic radiation.
Astronomy, which encompasses a broad range of fields like astrophysics, cosmology, and planetary science, is the study of space and its inhabitants. Human endeavor has also placed a lot of emphasis on space research, with numerous nations and organizations launching spacecraft to study the planets, moons, and other celestial bodies in our solar system and beyond.
