NASA: Hubble telescope captures detailed images of massive star explosionAbout 11.5 billion years ago, a distant star roughly 530 times larger than our sun died in a cataclysmic explosion that blew its outer layers of gas into the surrounding cosmos, a supernova documented by astronomers in blow-by-blow detail.

In the second image, the explosion is only a fifth as hot as in the first one. The remnant of the exploded star most likely became an incredibly dense object called a neutron star, Chen said. A phenomenon called strong gravitational lensing accounts for how Hubble was able to obtain three images at different points in time after the explosion.
