“Zombie star” baffles scientists by surviving supernovae

“A ‘zombie star’ which refuses to die has left astronomers stumped and questioning everything they know about supernovae. The star, which is 500 million light years away, was discovered in 2014 as it exploded and resembled a basic supernova that was getting fainter over time. But astronomers at the Las Cumbres Observatory in California were surprised to see it getting brighter a few months later. The star named iPTF14hls, which also exploded in 1954, has brightened and dimmed five times since its latest explosion. Usually, a supernova fades within 100 days but the ‘zombie’ star has been going strong for more than 1,000 days. It is currently fading slowly.” (11/09/17)
