Weird Supernova Remnant Blows Scientists’ Minds

Posted by in category: cosmology

When dying stars explode as supernovae, they usually eject a chaotic web of dust and gas. But a new image of a supernova’s remains looks completely different — as though its central star sparked a cosmic fireworks display. It is the most unusual remnant that researchers have ever found, and could point to a rare type of supernova that astronomers have long struggled to explain.

“I have worked on supernova remnants for 30 years, and I’ve never seen anything like this,” says Robert Fesen, an astronomer at Dartmouth College in Hanover, New Hampshire, who imaged the remnant late last year. He reported his findings at a meeting of the American Astronomical Society on 12 January and posted them in a not-yet-peer-reviewed paper on the same day.
