Scientists record flattest explosion ever seen in space

Astronomers have observed an explosion as big as our solar system but similar to that of an extremely flat disc. The explosion, which occurred 180 million light years away, challenges our current understanding of explosions in space, said researchers from the University of Sheffield in the UK. The explosion was a bright Fast Blue Optical Transient (FBOT), an extremely rare class of explosion that is much less common than other explosions, such as supernovas. The first bright FBOT was discovered in 2018.
