The Hubble Space Telescope recently observed something strange: an extremely bright, extremely fast flash of light that popped up in the middle of nowhere.
Technically known as a Luminous Fast Blue Optical Transient , the odd thing about this rare event was that it occurred outside of a galaxy.
“The Hubble observations were really the crucial thing. They made us realize that this was unusual compared to the other ones like that, because without the Hubble data we would not have known,” said lead researcher Ashley Chrimes in a statement. Related These flashes brighten and dim in just a few days, compared to other brief astronomical events like supernovas which tend to brighten and dim over a period of months. Scientists thought that LFBOTs might be created by a particular and rare type of supernova that happens to very large and short-lived stars. As these stars don’t last for long, they tend to be found close to stellar nurseries where they are born. But this new flash challenges that concept.
