Last year, astronomers discovered the brightest Luminous Fast Blue Optical Transient (LFBOT) ever observed. A complete understanding of this type of event, an exceptionally bright blue flash that quickly fades, has long eluded scientists. However, a new analysis of the brightest burst last year has unlocked key insights into the event, and scientists now believe the blue cosmic outburst is caused by black holes shredding massive cosmic companions, like stars.
