It would appear that a distant star has sprung back to life after its explosive death, blasting out repeated energetic flares over a period of several months that are like nothing astronomers have seen before.
Though each flash lasts just a few minutes even 100 days after the first eruption, they all remain as bright and as powerful as that original explosion — a rare type of stellar cataclysm called a "luminous fast blue optical transient" or LFBOT. This particular LFBOT is around a billion light-years from Earth and has been officially designated AT2022tsd, with its discoverers nicknaming it "the Tasmanian devil."
