Dark matter could make our galaxy's innermost stars immortal
Stars near the center of our galaxy are acting kind of weird. Dark matter may be the explanation.

X-ray binary Swift J1727.8-1613 has a large relativistic jet, observations show
Using the Very Long Baseline Array (VLBA) and the Long Baseline Array (LBA), astronomers have observed a black hole low-mass X-ray binary known as Swift J1727.8-1613. As a result, they found that the system hosts a highly ...
Simulations demonstrate potential mechanisms of intermediate-mass black hole formation in globular clusters
Joint research led by Michiko Fujii of the University of Tokyo demonstrates a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even ...

Chandra X-ray Observatory's clear, sharp photos help astrophysicist study energetic black holes
When a star is born or dies, or when any other very energetic phenomenon occurs in the universe, it emits X-rays, which are high-energy light particles that aren't visible to the naked eye. These X-rays are the same kind ...

Detecting 'Hawking radiation' from black holes using today's telescopes
In 1974 Stephen Hawking famously claimed that black holes should emit particles as well as absorb them. This so-called "Hawking radiation" has not yet been observed, but now a research group from Europe has found that Hawking ...
Black holes are firing beams of particles, changing targets over time
Black holes seem to provide endless fascination to astronomers. This is at least partly due to the extreme physics that takes place in and around them, but sometimes, it might harken back to cultural touchpoints that made ...

First proof that 'plunging regions' exist around black holes in space
An international team led by researchers at Oxford University Physics have proved Einstein was correct about a key prediction concerning black holes. Using X-ray data to test Einstein's theory of gravity, their study gives ...
