A decade ago, physicists using twin detectors in Washington State and Louisiana detected gravitational waves—subtle ripples ...

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 ...

For the first time, researchers have found evidence that even microquasars with low-mass stars can efficiently accelerate ...

Using the Gemini North telescope, astronomers have detected the largest black hole jet ever seen in the early universe. It's ...

From unifying quantum physics and gravity to working out what is dark matter, the universe has some deep questions that ...

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

Researchers said on Thursday that they had discovered twin-lobed radio jets they suspect were formed when the universe was ...

Sgr A*, at the heart of the Milky Way and clocking in at 4.3 million solar masses, is the closest supermassive black hole we have access to. It's also on the quiescent end of the activity scale, which ...

A cosmic mystery surrounding a black hole some 270 million light-years from the Milky Way is deepening. Now, the black hole has once again demonstrated strange features that teams of astronomers ...
