The Appearance of a Black Hole’s Shadow

In April of this year, the Event Horizon Telescope captured the first detailed images of the shadow of a black hole. In a new study, a team of scientists has now explored what determines the size and shape of black hole shadows like this one.

Three Black Holes May Merge in Nearby Galaxy

New observations of a galactic crash site show that there are not just two but three supermassive black holes on the verge of union. Two of them are only 650 light-years apart, the closest pair known.
