Can something explode in a vacuum?

In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically ‘explode’. But as long as the explosion doesn’t require oxygen, then it will work in much the same way in space as on Earth.
