A peculiar object discovered by the James Webb Space Telescope just 700 million years after the Big Bang could reveal the origins of the earliest black holes in the universe, some experts say.

At the heart of the Milky Way, just 27,000 light-years from Earth, there is a supermassive black hole with a mass of more than 4 million suns. Nearly all galaxies contain a supermassive black hole, and many of them are much more massive.

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling apples and orbiting planets.

Astronomers have confirmed the earliest, most distant black hole yet – and it's surprisingly monstrous for its time. Residing in a galaxy called CAPERS-LRD-z9, it was already approximately 300 million times the mass of the Sun just 500 million years ...

For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287. Roughly twice every 12 years, from 3.5 billion light years away, the light equivalent of 1 trillion suns flashes in the night sky and then fades away over the next few months.

The experiment at CERN produced pairs of electron and positron beams, propagating into an ambient plasma. The international team of researchers found that the beams were narrow and nearly parallel, with minimal disruption. These results suggest that the culprit is the weak intergalactic magnetic field, possibly a relic of the early universe.

If a new proposal by physicists bears out, the recent detection of a record-setting neutrino could be the first evidence of elusive Hawking radiation. (Nanowerk News) The last gasp of a primordial black hole may be the source of the highest-energy “ghost ...

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes might spew dark energy—and that they could help explain ...
