The explosion is more than 10 times brighter than any recorded exploding star – known as a supernova.
So far it has lasted more than three years, much longer than most supernovae which are usually only visibly bright for a few months.
One theory is that the blast was caused when a vast cloud of gas was swallowed up by a black hole.
