Astronomers discovered a bizarre "zombie" star that went supernova not just once, but twice

    To quote the first line of a letter published today in the journal Nature, “Every supernova so far observed has been considered to be the terminal explosion of a star.” In other words, when a massive star blows itself up, it should remain dead. This is something astronomers have witnessed thousands of times before with absolutely no exceptions.

    That is, until now.

    For the first time, astronomers have discovered a star that has gone supernova more than once. This so-called “zombie star” — which exploded at least twice in the last 60 years alone — has baffled scientists by challenging many of the existing theories about how massive stars end their lives.

    “This supernova breaks everything we thought we knew about how they work,” said the study’s lead author Iair Arcavi, a NASA Einstein Postdoctoral Fellow at the University of California-Santa Barbara and Las Cumbres Observatory, in a press release. “It’s the biggest puzzle I’ve encountered in almost a decade of studying stellar explosions.”

    The undying star, named iPTF14hls, was first discovered in September 2014 by the Palomar Transient Factory (PTF), a fully automated, wide-field survey designed to spot cosmic objects that vary in brightness over time — such as variable stars, transient objects, and, of course, supernovae.

    So this is what happens when 2 Death Stars and a Starkiller Base fail? The Empire/First Order build a damn zombie star?
