What Is There in Outer Space?
Space, also known as outer space, is the near-vacuum between celestial bodies. It is where everything (all of the planets, stars, galaxies and other objects) is found. On Earth, space begins at the Kármán line (100 km above sea level). This is where Earth's atmosphere is said to stop and outer space begins.

In this regard, what is outer space made of?

Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.

One may also ask, is there a difference between space and outer space? Explanation: Space and outer space are just two ways of describing the same thing: anything outside of Earth's atmosphere. Outer space provides a more specific type of space.

One may also ask, why is there outer space?

This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears. With no air to scatter sunlight and produce a blue sky, space appears as a black blanket dotted with stars.

What exists space?

The universe exists in space. To categorize there is Interplanetary space (the space between planets in our solar system), interstellar space (the space between stars in our galaxy), or intergalactic space (the space between galaxies in the universe). Whereas, Universe is all of time,space and its contents.
