The analyses also indicate that turbulence within the rotating envelope of gas that surrounds the black hole – the accretion disc – plays a role in changing its appearance. The first image of M87*’s ...

TL;DR: The James Webb Space Telescope observed Sagittarius A*, the supermassive black hole at the Milky Way's center, revealing flares from its accretion disk. The world's most powerful space ...

A new James Webb Space Telescope study finds that Sagittarius A*, the Milky Way's central black hole, constantly emits light from its swirling accretion disk. Credit: NASA / ESA / CSA / Ralf ...

Researchers say the accretion disk of hot gas surrounding the black hole, known as Sagittarius A*, throws off about five or six big flares a day, and several smaller bursts in between. frameborder="0″ ...

It's well known that huge black holes exist at the center of galaxies, including our Milky Way. But their role in cosmic ray production wasn't clear. Listen to Story Scientists have wondered where ...

The flares are likely emitted from the inner edge of the accretion disk—a flow of materials like gas or plasma that orbits black holes—and up to six larger flares were generated each day in ...

In an attempt to tackle these questions, a research team simulated the action of a so-called accretion disk around a supermassive black hole; not only could this simulation grant crucial insights ...

We don't know how these black holes grow so big. Current theoretical models propose that one pathway is growth via accretion and mergers, growing with their galaxies; but our current technology ...

Black holes are among the most mysterious objects in the universe. Their immense gravitational pull can warp space and time, yet they remain invisible unless they interact with their surroundings.

By peering deep into the heart of our galaxy, Webb has captured a continuous sequence of flares erupting from the black hole’s surrounding accretion disk. These flashes come ... reducing interference ...
