MAGNETAR-POWERED KILONOVA BLAST (VIDEO) W. M. Keck Observatory This video is under embargo. Please login to access this video.

In this sequence, two orbiting neutron stars spiral closer and closer together before colliding and merging. This triggers an explosion that unleashes more energy in a half-second than the Sun will produce over its entire 10-billion-year lifetime. The merger forms an even more massive neutron star called a magnetar, which has an extraordinarily powerful magnetic field. The magnetar deposits energy into the ejected material, causing it to glow unexpectedly bright at infrared wavelengths. Credit NASA, ESA, and D.
