Outer space
Outer space is the region that is located a hundred kilometres above the planet, and this area is characterised as a vacuum that does not carry any air in a significant amount to breathe or spread light in it. In addition to being empty air, sound does not travel in it because the molecules are not close enough to transmit sound between them. In this case, there is nothing after space, because space is everything. But even if the universe did have an end, it might be very difficult for us to figure out where the edge is Perhaps the most significant concern about bodies in space, though, is radiation, something that is manageable for today's astronauts flying in low-Earth orbit but would be a bigger deal for people traveling farther and for longer. The outer planets are gas giants Jupiter and Saturn and ice giants Uranus
