An astronaut is moving in space when a big explosion occurs about 50 metres behind him. how will the astronaut come to know about the explosion?

The matter from the explosion can reach him, hitting him. He should be able to feel that.

This is what i found “in a gas turbine engine, the combustor or combustion chamber is fed high pressure air by the compression system. early gas turbine engines used a single chamber known as a can type combustor. today three main configurations exist: can, annular and cannular (also referred to as can-annular tubo-annular).” i hope this you for what your looking for. can you plz mark me brainliest?
