Dead Stars Aren't Supposed to Do This

Dead stars are supposed to fade. In galaxy M83, a dozen did the opposite.

NASA's Chandra X-ray Observatory expected the supernova remnants there to keep
cooling and go dark. Instead they flared brighter. The leading idea: the X-ray
glow is gas each star shed years before it exploded, now lit up and ringing with iron.
