Biggest boom since the Big Bang? Astronomers record 25x supernova brightness

Astronomers have identified a new kind of cosmic explosion extreme nuclear transients so powerful they outshine typical supernovae by orders of magnitude and stay bright for years. Triggered when massive stars are torn apart by supermassive black holes, these rare events emit energy that challenges previous theories of stellar death.
