Dead Star Dubbed 'Tasmanian Devil' Comes Back To Life #space #sciencetime #universe Subscribe to Science Time: https://www.youtube.com/sciencetime24 Astronomers have witnessed a dead star, designated AT2022tsd or "the Tasmanian devil," unexpectedly bursting back to life. This distant star, about a billion light-years away, erupted with energetic flares months after its supposed death, displaying a rare phenomenon known as a "luminous fast blue optical transient" (LFBOT). These flares, as bright as the initial explosion and lasting just a few minutes each, have been observed repeatedly, defying typical post-explosion patterns. Discovered by 15 telescopes globally, this behavior suggests that the remnants of massive stars, like black holes or neutron stars, might be powering these LFBOTs. The Tasmanian devil was first identified in 2022 and continued to show unusual flare activity, leading to debates about the nature of these stellar explosions. This discovery could provide insights into the processes of stellar deaths and the early stages of stellar remnants, potentially altering our understanding of cosmic cataclysms.
