GW190521 was the name given to a gravitational wave event observed by LIGO and VIRGO in May 2019, and after a year of analysis and modelling it's now clear that not only was this the largest gravitational wave event ever recorded, but, it required progenitor black holes which were more massive than can be created by a supernova.
