Astronomers find a new luminous fast blue optical transient cosmic explosion

Using data from the Gemini South Telescope and other observatories, astronomers have found a new luminous fast blue optical transient (LFBOT), a powerful but poorly understood type of cosmic explosion characterized by intense blue light. The LFBOT occurred in the far outskirts of a galaxy, rather than nestled in a star-forming galaxy like other LFBOTs discovered so far.
