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.

Heavyweight Black Hole Find Mystifies Astronomers

Observations of a star have found it orbiting an unexpectedly massive black hole. If the discovery pans out, it would change our understanding of how massive stars die.

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.
