Unveiling a Brilliant and Ephemeral Cosmic Phenomenon

Astronomers have discovered a new class of cosmic explosion called Luminous Fast Coolers (LFCs) that outshines supernovas. These explosions are briefer and more spectacular than typical supernovas and likely represent a previously unstudied phenomenon. The LFCs occur in galaxies with sun-like stars that are too small to be supernova material. The explosions grow brighter and fade quicker than supernovas, and three such events have been identified so far. The most plausible explanation is a black hole colliding with a star, although the lack of X-ray emissions challenges this theory. Further research is needed to understand these mysterious explosions.
