When two black holes slam together, they do not simply vanish into darkness, they ring like struck bells and briefly light up ...

A detailed suite of simulations conducted by astrophysicists at the Flatiron Institute and their collaborators showed that magnetic fields can produce black holes with masses that were previously ...

A new study on some 1,600 galaxies based on data from the Chandra X-ray Observatory reveals that many small galaxies do not ...

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...

Astronomers usually detect black holes by looking for X-rays. When gas and dust fall toward a black hole, they heat up and ...

The James Webb Space Telescope has just confirmed a cosmic fugitive: the first known supermassive black hole racing through ...

In December 2019, an ordinary galaxy 300 million light-years from us in the constellation Virgo suddenly woke up. After decades of inactivity, the black hole at the galaxy's heart burst with light.

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

Most smaller galaxies may not have supermassive black holes in their centers, according to a recent study using NASA's Chandra X-ray Observatory. This contrasts with the common idea that nearly every ...

Using the James Webb Space Telescope, astronomers discovered an extreme version of "little red dots" dubbed "The Cliff." Its light suggests that it could be a never-before-seen class of objects called ...

A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously ...
