After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have found that a black hole that shredded a star has moved onto a another star or stellar black hole. Credit: NASA/CXC/A. Hoba ...

A small black hole would plunge straight into the event horizon, while a normal star would quickly be torn apart by tidal forces. But astronomers theorize that a low-mass white dwarf, a compact ...

Then, as it gets closer, the star is quite literally ripped apart and sucked into the black hole itself. This process is formally called a tidal disruption event. Now, NASA is hoping to learn more ...

If Earth was (hypothetically) crushed into a black hole ... An artist's rendering of a white dwarf star speeding around the black hole 1ES 1927+654. A stream of particles trails the dense star.

Rather than relying on a cheek swab or a little blood, however, these cosmic DNA tests utilize tiny ripples in the fabric of ...

"This is the first solid evidence that helical magnetic fields can explain astrophysical jets at different scales." ...

By combining data from NASA’s IRAS and NuSTAR telescopes, scientists have uncovered more hidden supermassive black holes than earlier estimates suggested. Their findings indicate that over a third of ...

While the black hole’s gravity may pull the white dwarf inward, the star is also shedding part of its outer layer into the black hole. This shedding acts as a small kick-back, such that the ...

"There is every chance of us finding one [an intermediate-mass black hole] soon," Read said. "More and more pulsar accelerations are coming, allowing us to peer into the centers of dense star ...

Some of these black holes spit out some of the accreting gas into intergalactic space in the form of relativistic jets, further stripping the galaxy of the star-bearing medium. The JWST ...
