Wonderful!! 83 supermassive black holes found in the early universe

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the sun. While they...
Artist conception of information falling into a black hole. Researchers have implemented an experimental test for quantum scrambling, a chaotic shuffling of the information stored among a collection of quantum particles. The experiment was originally inspired by the physics of black holes. Quantum scrambling is one suggestion for how information can fall into a black hole and come out as random-looking radiation. Perhaps, the argument goes, it’s not random at all, and black holes are just excellent scramblers. (Credit E. Edwards/JQI)

Untangling information about what a black hole ate

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so...
This image shows the merger of two galaxies, known as NGC 7752 (larger) and NGC 7753 (smaller), also collectively called Arp86. In these images, different colors correspond to different wavelengths of infrared light. Blue and green are wavelengths both strongly emitted by stars. Red is a wavelength mostly emitted by dust.

Why do some galactic unions lead to doom?

NASA's Spitzer Space Telescope recently releases some pictures that show pairs of galaxies on the cusp of cosmic consolidations. Even though the galaxies appearing...
Bright green sources of high-energy X-ray light captured by NASA's NuSTAR mission are overlaid on an optical-light image of the Whirlpool galaxy (in the center of the image) and its companion galaxy, M51b (the bright greenish-white spot above the Whirlpool), taken by the Sloan Digital Sky Survey.Credit: NASA/JPL-Caltech, IPAC

In colliding galaxies, a pipsqueak shines bright

In the nearby Whirlpool galaxy and its companion universe, M51b, two supermassive black holes heat up and devour encompassing material. These two beasts ought...
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...
