What’s in space?
Space is not completely empty.It is not a perfect vacuum. There are particles and electromagnetic waves travelling through Space. It is also filled with huge amounts of thinly spread gas and dust. Even the emptiest parts of space contain at least a few hundred atoms or molecules per cubic meter.
Space is also filled with many forms of radiation that are dangerous to astronauts.
What is Space Day?
