A new form of black hole archeology, linking spin to gas and dust, has revealed that these cosmic titans spin faster than ...

The 2018 observations confirmed the luminous ring seen in 2017, with a diameter of about 43 microarcseconds, matching theoretical predictions for the shadow of a 6.5 billion solar-mass black hole. The ...

The speed at which a black hole spins is difficult to distinguish from the speed at which the surrounding flattened cloud of gas and dust — the accretion disk — rotates. "The challenge lies in ...

Observations from 2017 and 2018 by the Event Horizon Telescope have enhanced understanding of the supermassive black hole M87*, focusing on its turbulent accretion flow.

This material generates a flattened, swirling cloud of gas and dust called an accretion disk around the black hole. The tremendous mass of the supermassive black hole generates tidal forces and ...

"The problem is that mass is hard to measure, and spin is even harder." The speed at which a black hole spins is difficult to distinguish from the speed at which the surrounding flattened cloud of gas ...

Scientists know that a black hole's intense gravitational pull creates an accretion disk, or a swirling mass of gas, dust, plasma, and other particles that are eventually swallowed by the black ...

How much does a black hole change in a year? Scientists may now have an idea, after taking a fresh look at the first-ever black hole to be imaged — the supermassive black hole M87*, , which ...

Measuring that region is important since knowing the black hole's mass and its accretion disk's structure provides data that allows them to measure the spin rate. Astronomers typically estimate ...
