"We are really pushing the edges, and are seeing things that are more massive, spinning faster, and are more astrophysically ...

Astronomers believe that nearly every large galaxy contains a supermassive black hole at its center. But one giant galaxy located billions of light-years away appears to be missing its cosmic anchor.

New analysis suggests Webb’s little red dots are young black holes hidden in thick gas, with masses far smaller than first ...

A NASA animation has sized the biggest black holes known to scientists, including one that has the mass of 66 billion Suns.

Some of the universe’s most extreme explosions leave behind almost no trace. The original explosion is unseen, but our ...

Gravitational lenses could allow us to find black hole binaries long before we're able to measure their gravitational waves.

Study led by University of Bonn finds galaxy clusters contain about twice as much normal matter as previously estimated, based on recalculated stellar populations and survey data.

During the survey, researchers identified a promising 8.19-millisecond pulsar (MSP) candidate located close to Sagittarius A*, the supermassive black hole at the center of our galaxy.

Observations of a distant quasar reveal that supermassive black holes may suppress star formation across intergalactic distances.

The Los Angeles Unified School District is weighing mass layoffs as it faces a deficit of nearly $200 million – driven by huge salaries and plummeting enrollment. The board is expected to meet next ...

Galaxy clusters, the largest structures held together by gravity in the universe, may be far heavier than scientists once believed. New research suggests that much of their “missing” mass could be ...
