Gravitational waves may come from dying stars’ cocoons (video)

The ‘cocoons’ of debris that surround dying stars appear to be able to create tiny ripples in space-time.

So far, astronomers have only detected these ripples, known as gravitational waves, when they have been triggered by cataclysmic mergers of pairs of orbiting black holes, neutron stars or a combination of the two. As these very dense objects spiral toward each other in a cosmic dance that spans millions of years, they distort the fabric of space and time, sending out gravitational waves in the process.
