#Astronomers have found a new and unknown object in the #MilkyWay that is heavier than the heaviest #neutronstars known and yet simultaneously lighter than the lightest #blackholes known.
Anatomy of a kilonova (2017) - Aftermath of the merger between two neutron stars, initially observed in the form of the gravitational waves event GW170817.
Jocelyn Bell Burnell transformed astronomy #OTD in 1967 when she made the first observation of a pulsar.
She and advisor Antony Hewish initially dubbed the object LGM-1 (“Little Green Men”) for its regular signal, but soon identified it as a rotating, magnetized neutron star.
