NASA’s Hubble Space Telescope captures Rare Exploding Supernova

Astronomers know that a number of stars end their life with an explosion, but it is very rare when these acts are captured. But now, astronomers have captured an image of the stellar activity, thanks to NASA’s Hubble Space Telescope.

The astronomers not only imaged the young star in action, but also predicted the first supernova coming. The space telescope in low earth orbit captured the stellar explosion in action on December 11, 2015.

The supernova, named Refsdal, has been captured by Hubble in the galaxy cluster MACS J1149.5+2223. Light from the cluster took approximately 5 billion years to reach earth’s surroundings, but the star exploded about 10 billion years ago, according to the astronomers.

It is the first time when astronomers have spotted anything like it. Ryan Foley, a researcher from the University of Illinois at Urbana-Champaign who observed the distant star blowing itself, said, “This is incredibly fun. It's amazing to work on something that you know will one day be in a textbook”.

The story of Refsdal’s explosion started last year in November when astronomers captured four photographs of the supernova. It was in a rare arrangement, called an Einstein Cross, around a galaxy, according to the astronomers.

Steve Rodney of the University of South Carolina said the time when the supernova was studied, it was observed that the galaxy in which the explosion took place is a galaxy being lensed by the cluster.
