By using protons to probe how a magnetic field responds to an expanding plasma, experimenters have replicated the particle jets spewed out by active black holes.
Researchers have discovered compelling evidence suggesting that the supermassive black hole at the center of our Milky Way galaxy, known as Sagittarius A* (Sgr A*), is likely the result of a past cosmic merger. The study builds on recent…
The origins of aptly named supermassive black holes—which can weigh in at more than a million times the mass of the sun and reside in the center of most galaxies—remain one of the great mysteries of the cosmos.
Neutron stars are timelike matter with a maximum mass of about 2.34 solar masses in quantum chromodynamics (the strong color force). Black holes are spacelike matter that have no maximum mass, but a minimum mass of 2.35 solar masses.…
By demonstrating the ability for joint observations at the short radio wavelength of 0.87mm, the Event Horizon Telescope has improved its observational acuity by half.
Black holes are by their very nature, challenging to observe and difficult to spot. It’s usually observations of the accretion disk that reveal properties of the hidden black hole. There is often enough material within the accretion disk…
QUENTIN LETTS: Rachel Reeves , our peculiar new Chancellor, was taking her first Commons Treasury questions. 'Black hole,' she quacked. 'Black hole. Black hole. Black hole.'
Black holes are famous for sucking in everything that crosses their event horizons, including light. So, why do astronomers see energetic radiation coming from the environment of a black hole in an X-ray binary system? It’s a good question…
