Astronomers have found the first direct evidence that a wandering black hole can feed itself by dragging gas along in its wake as it moves through its galaxy. It's the first direct evidence of an accretion channel long predicted ...
Nearly every galaxy has a supermassive black hole. The few that don't have had theirs ejected during a galactic collision. That's because galaxies and their black holes have formed hand in hand. There is still some debate ...
Intense, brief flashes of radio light called fast radio bursts (FRBs) travel across billions of light-years to reach Earth, passing through a fog of matter along the way. The bursts' origins are unclear but may originate ...
Active black holes are easy to detect. Their superheated accretion disks emit bright X-rays, and the jets streaming from their poles are easily seen at visible and radio wavelengths. But most stellar-mass black holes are ...
We know the universe is constantly expanding. We also know that gravitationally bound objects, such as solar systems and black holes, seem to be immune to that expansion. But a new paper by theoretical physicists Valerio ...
A new study finds that two early-universe objects thought to be faint quasars are actually extraordinarily luminous galaxies powered by bursts of star formation. James Webb Space Telescope observations of the galaxies, seen ...
In 2012, the Dark Energy Spectroscopic Instrument (DESI) was commissioned to measure the effect of dark energy, the mysterious force driving the expansion of the cosmos. Since then, the DESI Legacy Imaging Surveys have obtained ...
Current gravitational-wave observatories aren't sensitive enough to capture the gravitational waves of binary stars. They can only see the gravitational chirps of black holes just as they are merging. But that will change ...
When two black holes crash together and merge, the newly formed black hole rings like a bell, sending out gravitational waves with specific frequencies that fade over time. This brief, fading pattern of waves is called ringdown, ...
The Sloan Digital Sky Survey (SDSS), the largest multispectral imaging and spectroscopic redshift survey of the cosmos, has released its 20th data release (DR 20). It is also the third release of the survey's fifth phase ...
