18, 2025 — Astrophysicists have observed our central supermassive black hole. They found the accretion disk is constantly emitting flares without periods of rest. Shorter, faint flares and ...

Greek astronomer Dimitrios Psaltis was instrumental in the gigantic effort to take mankind's first-ever image of a black hole ...

The stellar wind from a nearby blue supergiant star is streaming into the black hole, forming an accretion disc about the black hole's axis of rotation. Some of that accreted material is then cast ...

At the center of our galaxy, hidden behind dense clouds of gas and dust, the black hole Sagittarius A* rotates rapidly, ...

Early research focused primarily on low-luminosity black hole sources with quasi-spherical accretion flow as these systems are comparatively easier to simulate and align with many observed jets.

Astronomers believe the flares are coming from the inner edge of the accretion disk just beyond the black hole’s event horizon, or the area around a black hole where the pull of gravity is so ...

For this reason black holes are invisible to the eye, as lightless as the empty, dark space surrounding them. Scientists know they exist not because they can see an actual hole, b ...

so it all gathers in orbit around the black hole and forms an accretion disk. Friction happens within the disk, which generates large amounts of light radiation that can be seen and measured by ...

Astronomers have discovered a record-breaking black hole moving at over 1,000 km/s, believed to have been ejected after ...
