An international team of astronomers reports the detection of a new tidal disruption event (TDE) as part of All-Sky Automated Survey for SuperNovae (ASAS-SN). The newfound TDE, designated ASASSN-23bd, turns out to be the ...
For many years, most astrophysical models assumed that planets beyond our solar system, known as exoplanets, are heated at similar depths by their host stars (i.e., stars like the sun around which planetary systems are formed). ...
Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.
