Black holes

Astronomers have discovered a "missing link:" a tiny black hole lurking with a red giant star in a strange and difficult-to-explain binary system.

The first results from JAXA's XRISM X-ray telescope are out, and they reveal new features of the superheated gas around a distant supermassive black hole and a closer supernova.

Astronomers have seen the largest jets ever found erupting from a black hole. The giant jet system Porphyrion is 23 million light-years long, equal to 140 side-by-side Milky Way galaxies.

"If there are lots of black holes out there, some of them must surely pass through our backyard every now and then."

Using the James Webb Space Telescope astronomers have observed a supermassive black hole "killing" its galaxy by starving it of the material needed to birth new stars.

The tag team of NASA space telescopes Hubble and Chandra has demonstrated that two is definitely better than one when it comes to pairings of supermassive black holes and hunting for them.

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.

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.

A tiny fraction of known black holes emit X-ray signals that resemble a human "heartbeat." Now, new research may finally explain the strange phenomenon.
