What’s That Smell
Outer space actually has its own distinct scent, and it’s a smelly universe that we live in. While we can’t smell anything in outer space because, as we mentioned, anyone attempting to do so would almost instantly die, what we can smell are the things that have come back from space. The lingering scent smells like a combination of charred meat, hot metal, and fuel. Scientists believe that it could come from polycyclic aromatic hydrocarbons, which are high-powered particles released into space during the nuclear reactions that power stars and supernovae.
