NASA news: Hubble telescope’s stunning view of galaxy lit by two supernova explosions

“At this point, the star collapsed inward before exploding outward in a brilliant supernova.”

Although the two events are no longer visible in Hubble’s photo, the supernovas were seen from Earth when they occurred.

The first was seen on November 13, 1975, and the second on November 8, 2015.

Astronomer Greg Crinklaw, developer of Sky Tools, photographed the second supernova on January 21, 2015.

He wrote on his website: “For over a hundred million years the light travelled across the void, eventually entering our own galaxy, and solar system, with some small part finding its way through the atmosphere of the earth and into a telescope.
