'When a star reaches the end of its life, it explodes in one final cataclysmic blast that can shine with the light of 100 million suns for months, before fading into the blackness of space. This was thought to be end awaiting all stars - until now.
An international team of astronomers studying supernova explosions has discovered a “zombie star” that has repeatedly gone through this death cycle over the last half century. The star in question, iPTF14hls, was discovered in 2014 and it looked like any ordinary - if you can call an exploding star ordinary - supernova.
However, upon closer inspection, the team noticed that instead of disappearing completely into darkness, once faded it began to glow brighter again. No one has ever witnessed anything like this before.'
