‘Betelgeuse on steroids’ shows how rare massive stars die

A new map of one of the most massive stars in our galaxy sheds light on what happens in the final stages of a giant star’s death.

Astronomers have created a detailed 3D map of VY Canis Majoris, a dying red hypergiant star located more than 3,000 light years from Earth. They found that the way this rare supergiant star loses mass is analogous to coronal arcs – loops of plasma that burst from the Sun – but on a scale billions of times greater.
