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

The most extreme black hole collision ever recorded looked, at first, like it should not have happened at all. Two objects each weighing roughly as much as one hundred Suns crashed together in a ...

What could force a supermassive black hole (SMBH) out of its host galaxy? They can have hundreds of millions, even billions ...

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 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 ...

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

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.

Using the James Webb Space Telescope, a team of international researchers have discovered chemical fingerprints of gigantic ...

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 ...
