Unusual collision triggers supernova explosion in binary star system

When stars collapse under their own gravity, they can leave behind a neutron star or black hole — provided that the star is massive enough. In a binary star system, this can lead to some pretty wicked interactions. When stars collapse under their own gravity, they can leave behind a neutron star or maybe a […]
