‘Betelgeuse on steroids’ shows how rare massive stars die


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

Astronomers created a detailed 3D map of VY Canis Majoris, a dying red hypergiant star   located over 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 erupt from the sun — but on a scale billions of times larger.
