This star was supposed to explode as a supernova, but astronomers found another explanation
SMRTR summary
A star called AT 2016blu, located 29 million light-years away, was long expected to explode as a supernova due to its massive size and 27 recorded outbursts. New X-ray observations suggest a different explanation: the star is part of a binary system, with a companion object pulling matter from it. That companion could be a black hole or neutron star, though its exact nature remains unknown.
