The event, nicknamed Tasmanian devil, is puzzling scientists who don't know what is causing it. Ho and colleagues' observations suggest the Tasmanian devil released at least 14 irregular and highly energetic bursts, each lasting only a few minutes. This leaves a neutron star or a black hole surrounded by the remnants of a partial star. To produce such brilliant flares, a black hole or neutron star would need a lot of fuel. AdvertisementAnother possibility is that the Tasmanian devil was caused by a star merging with a black hole or a neutron star, said Ho.

CNN —Space is full of extreme phenomena, but the “Tasmanian devil” may be one of the weirdest and rarest cosmic events ever observed. Astronomers dubbed the celestial object the “Tasmanian devil,” and they observed it exploding repeatedly following its initial detection in September 2022. But the Tasmanian devil is revealing more questions than answers with its unexpected behavior. While LFBOTs are unusual events, the Tasmanian devil is even stranger, causing astronomers to question the processes behind the repetitive explosions. We’d never seen that, period, in astronomy.”To better understand the quick luminosity changes occurring in the Tasmanian devil, Ho and her colleagues reached out to other researchers to compare observations from multiple telescopes.

Scientists had previously thought Luminous Fast Blue Optical Transients were caused by dying stars. AdvertisementAdvertisementA bright flash of blue light appearing in the middle of seemingly empty space has scientists confused. Scientists previously thought they knew what could cause such a bright burst of energy. That's much too far for a core-collapse supernova to travel. There are a few more hypotheses for what could cause the bright blue flashes.

What do a cow, a koala, a camel, a Tasmanian devil and now a finch all have in common? They are nicknames given to a weird class of space explosions scientists can’t explain. They are more technically called luminous fast blue optical transients, or LFBOTs. These space explosions are much brighter than supernovas (which occur when stars explode), hence the “luminous” designation. They brighten quickly — hence “fast” — and are extremely hot, reaching 70,000 degrees Fahrenheit, and thus emitting “blue” light.
