A deep space photographer spent months photographing the Crab Nebula and found his composite image, when compared with the 1999 image from the Hubble Space Telescope, shows the supernova's expansion.

When a massive star runs out of fuel and approaches the end of its life, it explodes in a huge outpouring of energy called a supernova. These events can be so bright that they outshine entire galaxies ...

The powerful gravity of a galaxy embedded in a massive cluster of galaxies in this Hubble Space Telescope photo is producing multiple images of a single distant supernova far behind it. Both the ...

The Hubble space telescope has captured supernova images from three different moments, according to a new video released by NASA Goddard. The video, which can be found embedded below, showcases the ...

A cosmic camera hog is helping astronomers figure out the rate of the universe’s expansion. Images of the supernova Refsdal have popped up multiple times in the constellation Leo, thanks to light from ...

Light from a supernova explosion in the nearby starburst galaxy M82 is reverberating off a huge dust cloud in interstellar space. The supernova, called SN 2014J, occurred at the upper right of M82, ...

NASA’s Hubble Space Telescope has identified a star that was one million times brighter than the Sun before it exploded as a supernova in 2005. According to current theories of stellar evolution, the ...
