Andromeda star quietly collapses into a black hole, archival data reveal
TL;DR
Astronomers using archival NEOWISE infrared data have captured the clearest evidence yet that a massive star in the Andromeda Galaxy directly collapsed into a black hole, after brightening in infrared for about three years and leaving a dust shell; the event (M31-2014-DS1) from 2014 suggests some massive stars die without a supernova, refining ideas about stellar deaths.
