Why There Is no Sound in Space

Space is a nearly perfect vacuum. Because sound waves can not pass through a vacuum there can be no sound in space. Space is silent.
A space shuttle launch is very loud when the rocket is still in Earth’s atmosphere. Once the shuttle reaches space however it is silent.
As a star ship zips across the universe, it does so perfectly silently. If a starship is destroyed in a space battle, the violent explosion, seen from a safe distance will be eerily silent.
Supernovas are violent explosions of entire stars that release as much energy in about a year as the Sun releases in its 10 billion year lifetime. Astronomers observe the light from these stellar explosions, but never hear them. Light waves travel through space. Sound waves cannot.

    Interesting information shared. There are no waves present in space as there is no air. And that’s why we cannot hear any sound from space.
