Astronomers studying what may be the most powerful supernova ever seen

Right now, astronomers are viewing a ball of hot gas billions of light years away that is radiating the energy of hundreds of billions of suns. At its heart is an object a little larger than 10 miles across. And astronomers are not entirely sure what it is.

If, as they suspect, the gas ball is the result of a supernova, then it’s the most powerful supernova ever seen.In this week’s issue of the journal Science, they report that the object at the center could be a very rare type of star called a magnetar–but one so powerful that it pushes the energy limits allowed by physics.

An international team of professional and amateur astronomers spotted the possible supernova, now called ASASSN-15lh, when it first flared to life in June 2015. Source:  ScienceDaily
