In this illustration of a newly discovered black hole named MAXI J1820+070, a black hole pulls material off a neighboring star and into an accretion disk. Above the disk is a region of subatomic particles called the corona. Credit: Aurore Simonnet and NASA’s Goddard Space Flight Center

NASA’s NICER mission maps light echoes of new black hole

Using NASA’s Neutron star Interior Composition Explorer (NICER), NASA scientists observed the environment surrounding a stellar-mass black hole that is 10 times the mass...
Measuring the expansion of the Universe

Active Galaxies point to new physics of cosmic expansion

Exploring the history of the universe with a large sample of distant ‘active’ galaxies observed by ESA’s XMM-Newton, a team of astronomers found there...
This visualization of a general-relativistic collisionless plasma simulation shows the density of positrons near the event horizon of a rotating black hole. Plasma instabilities produce island-like structures in the region of intense electric current. (Credit: Kyle Parfrey et al./Berkeley Lab)

Simulations provide new clues to what’s driving powerful plasma jets

How black holes clean energy secured in their rotation, jetting near-light-speed plasmas into space to opposite sides in one of the most powerful displays...
The Chandra images show pairs of huge bubbles, or cavities, in the hot gaseous atmospheres of the galaxies, created in each case by jets produced by a central supermassive black hole. Credit: X-ray: NASA/CXC Illustration: CXC/M. Weiss.

Scientists spotted black hole spinning rapidly around itself

Using observations from state-of-the-art technology, the team of researchers led by the University of Southampton- found evidence that a stellar-mass black hole in our...

Birth of a black hole or neutron star captured for first time

Scientists at the Northwestern University have captured the mysteriously bright object that burst in the northern sky this summer. Dubbed AT2018cow or “The Cow,” the object...
This artist's impression shows hot gas orbiting in a disk around a rapidly-spinning black hole. The elongated spot depicts an X-ray-bright region in the disk, which allows the spin of the black hole to be estimated. Image: NASA/CXC/M. Weiss

X-ray pulse detected near event horizon as black hole devours star

On Nov. 22, 2014, stargazers detected an uncommon vent in the night sky: A supermassive black hole at the center of a galaxy, almost...
