Cygnus X-3, studied by XRISM, pairs a Wolf-Rayet star and compact object XRISM’s Resolve spectrometer captured intricate gas ...

Black holes are the most extreme objects in the universe. These hyper-dense celestial phenomena exert gravitational forces so powerful that not even light can escape their pull, and time itself is ...

Peculiar James Webb Space Telescope observations seem to show gargantuan black holes in the earliest moments of the universe. New research may explain how they formed, thanks to primordial "seeds".

When pulsars accrete too much material, they can form black holes. Spider pulsars don't tempt the same fate. Vidal calls ...

AI-generated representation of an accreting supermassive black hole, surrounded by gas spiraling toward it along the equatorial plane (the accretion disk) and emitting powerful winds of matter as it ...
