If there is no sound in space does that mean stars are silent?

Question

I did Google this a bit and understand that sounds needs a medium to travel.

So if we could hypothetically stand in the surface of the sun would we hear nothing?

If two asteroids collided would it be completely silent?

Answer 1

So, with the understanding that sound is just vibrations in the air, and in a vacuum there is no air, so sound is not possible… However, stars and asteroid collisions do result in the emission of energy, but it can’t be dissipated as sounds, as it might in an atmosphere, instead that energy is emitted as heat/radiation as well as kinetic in the case of collisions
