Named LID-568, this 7.2-million-solar-mass black hole appears to be feeding on matter at a rate 40 times its Eddington limit and is seen as it existed just 1.5 billion years after the Big Bang.

At a distance of about 1,400 parsecs (4,600 light-years), Cygnus OB2 is the closest massive young association to the Sun. It contains hundreds of massive stars as well as thousands of lower-mass stars ...
