If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...

What exists at the core of a black hole? A research team led by Enrico Rinaldi, a physicist at the University of Michigan, ...

From unifying quantum physics and gravity to working out what is dark matter, the universe has some deep questions that ...

It turns out that the strength of this quantum effect depends on the mass of black holes: small-mass black holes would produce Hawking radiation more efficiently and are more unstable. However ...

Messier 87 (M87), also known as Virgo A or NGC 4486, is a supergiant elliptical galaxy in the Virgo constellation. It is one ...

Scientists have found that supermassive black holes self-grow by regulating the cooling of surrounding hot gas, forming warm gas filaments that they consume. This discovery enhances the ...

It's no secret that black holes are some of the weirdest objects in space. Their disks are fluffy like cake, and diving into one is both interesting and terrifying. Now, a group of astronomers ...

Many believe that the only aspect is the Doppler Effect, which is utilized by forecasters like Michael to predict incoming weather conditions, but the phenomena has far reaching applications since ...

Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge.

Black holes aren't just gorging themselves on whatever cosmic material is readily available—they're preparing those meals for themselves. Data from NASA's Chandra X-ray Observatory reveals that ...

Highly energetic explosions in the sky are commonly attributed to gamma-ray bursts. We now understand that these bursts ...
