European astronomers report the detection of a new giant radio galaxy (GRG) as part of the LOFAR Two-meter Sky Survey (LoTSS). The newly found object, named Alcyoneus, turns out to be the largest GRG known to date. The finding ...
The European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI) has observed a cloud of cosmic dust at the center of the galaxy Messier 77 that is hiding a supermassive black hole. The findings have confirmed ...
