V404 Cygni Rings (Credit: X-ray: NASA/CXC/U.Wisc-Madison/S. Heinz et al.; Optical/IR: Pan-STARRS) A spectacular set of rings around a black hole has been captured using NASA’s Chandra X-ray Observatory and Neil Gehrels Swift Observatory. The X-ray images of the giant rings have revealed new information about dust located in our Galaxy, using a similar […]

ANIMATION Emirati national Aisha Al Yazeedi, a research scientist at the NYU Abu Dhabi (NYUAD) Center for Astro, Particle, and Planetary Physics, has published her first research paper, featuring some key findings on the evolution of galaxies. Galaxies eventually undergo a phase in which they lose most of their gas, which […]

In 1916, Albert Einstein put the finishing touches on his Theory of General Relativity, a journey that began in 1905 with his attempts to reconcile Newton’s own theories of gravitation with the laws of electromagnetism. Once complete, Einstein’s theory provided a unified description of gravity as a geometric property of […]

An artist’s impression of two black holes about to collide and merge. Study offers evidence, based on gravitational waves, to show that the total area of a black hole’s event horizon can never decrease. There are certain rules that even the most extreme objects in the universe must obey. A […]

Scientists at University of Chicago and University of California, Riverside have put forward a surprising theory to explain mysterious, supermassive black holes that formed early in the universe; those black holes could have formed with the help of dark matter. Credit: ESA/ATG medialab Scientists offer new theory to explain the […]

An artistic image inspired by a black hole-neutron star merger event. Credit: Carl Knox, OzGrav/Swinburne Mix pair is “elusive missing piece of the family picture of compact object mergers.” A long time ago, in two galaxies about 900 million light-years away, two black holes each gobbled up their neutron star […]

ANIMATION UC Riverside-led study points to a seed black hole produced by a dark matter halo collapse. Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million […]

Artist’s impression of a galactic wind driven by a supermassive black hole located in the center of a galaxy. The intense energy emanating from the black hole creates a galaxy-scale flow of gas that blows away the interstellar matter that is the material for forming stars.

Supermassive black holes (SMBH) occupy the center of galaxies, with masses ranging from one million to 10 billion solar masses. Some SMBHs are in a bright phase called active galactic nuclei (AGN). AGNs will eventually burn out since there is a maximum mass limit for SMBHs; scientists have long since […]
