Can You Hear an Explosion in Space?

In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically 'explode'.

Can you hear an explosion in the outer space explain your answer?

To travel to us from outer space, the wave must be able to travel through regions of space which are essentially vacuum (nothing there). Sound cannot do this, as it requires a medium to propagate in, so we would not be able to hear the explosion.

Would an explosion in space have a Shockwave?

Supernovae create powerful shocks, both within the star collapsing to form the explosion and also moving through the interstellar medium itself. Interstellar shocks can also occur simply by the collision or collapse of gas clouds.
