Rotating black holes are the most powerful phenomenon in the known universe. Their powerful gravity radically alters the curvature of spacetime around them, leading to relativistic effects like time ...

Called an accretion disk, this ring of matter around Sagittarius A* spewed everything from brief flickers that only last a few seconds to incredibly bright daily eruptions to even faint flickers ...

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 ...

While black holes are invisible, the flares unleashed by the swirling disk of hot gas and dust, or accretion disk, that orbits Sagittarius A* resemble a pyrotechnic extravaganza. A study ...

Using the ROentgen SATellite (ROSAT), astronomers have discovered a new cataclysmic variable system of the polar subtype. The ...

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 ...

This finding provides compelling evidence that the giant planets in HR 8799 formed through core accretion, a process similar ...

NASA's Webb telescope has captured images of multiple planets in a nearby star system, confirming that Webb can infer exoplanet atmospheres' chemistry.

The disc of plasma surrounding the black hole at the heart of the Milky Way is constantly emitting flares both large and small.
