A new astronomical transient that is faster, brighter, and heavier at radio wavelengths has been spotted.
The USA's Northwestern University-led team determined that the anomaly is the third fast blue optical transient (FBOT) ever captured in X-ray and radio wavelengths.
It was after a bright burst was visually captured, in 2016, by the astronomers in a tiny galaxy 500 million lightyears away from Earth.
The most famous FBOT is AT2018COW (“The Cow”) - a rare event that appeared to be the birth of a neutron star or black hole.
