Often referred to as outer space, it is the void that exists beyond any planets. It is not entirely empty as it contains low density particles, hydrogen plasma and electromagnetic radiation as well as magnetic fields and neutrons. It was discovered in 350 BC by the philosopher Aristotle and was at first suggested to be a vacuum called horror vacuum.
However, it was eventually discovered that a vacuum could not exist and it was held for many centuries that space could not have been entirely empty.
Earth has been shown in many comic books in a lot of adventures by a large number of heroes and villains who have visited space. It had been pictured in many comic books mainly in science fiction novels.
