The historic neutron-star crash that astronomers observed last year didn't generate a black hole after all, at least not initially, a recent study suggests.
In October 2017, researchers announced that they had detected both light and gravitational waves the ripples in space-time first predicted by Albert Einstein a century ago emanating from the merger of two superdense stellar corpses known as neutron stars.
This epic collision called GW170817, because it was first spotted on Aug. 17, 2017 marked the beginning of the era of "multimessenger astrophysics," astronomers said. This term refers to the study of a cosmic object or phenomenon using at least two different types of signals. [Neutron-Star Crash: A Gravitational Waves Discovery in Pictures]
Data gathered by the Laser Interferometer Gravitational Wave Observatory (LIGO) project indicated that the object created by the merger was about 2.7 times more massive than the sun. That's right on the neutron star-black hole borderline, so the identity of the newly formed body was unclear: It was either the least massive black hole ever discovered, or the most massive neutron star.

If I had an 80's garage band, Hypermassive Magnetar would have been a good name...
