New Research Solves Key Mystery in the Birth of Massive Black Holes
When the universe was still a baby – less than 1 billion years old – some of its stars turned into monster black holes. A…
New Simulations Provide Clues on How to Escape a Black Hole
Black holes are known for their voracious appetites, binging on matter with such ferocity that not even light can escape once it’s swallowed up. Less…
Breakthrough Allows Astronomers To See What Makes Sagittarius A* Glow
A black hole four million times as massive as our Sun lurks at the center of the Milky Way. This black hole, called Sagittarius A*…
Scientists Reveal Orderly Chaos of Black Holes
An international consortium of scientists studying gamma-ray bursts (GRBs) as part of the POLAR (GRB polarimeter) experiment has revealed that high-energy photon emissions from black…
Astronomers Reveal New Way Supermassive Black Holes Are “Fed”
Supermassive black holes weigh millions to billions times more than our sun and lie at the center of most galaxies. A supermassive black hole several…
Chandra Views Never Before Seen Behavior From Giant Black Hole
Astronomers have discovered behavior by a jet from a giant black hole that has never been seen before. Using NASA’s Chandra X-ray Observatory they have…
Astronomers Discover Intermediate Mass Black Holes in Galactic Nuclei
The existence of black holes is well established, and observations have found both stellar mass sized objects and giant ones millions to billions times more…
New Equations Go Beyond Einstein’s Theory of General Relativity
When stars collapse, they can create black holes, which are everywhere throughout the universe and therefore important to be studied. Black holes are mysterious objects…
GRAVITY Measures Environs of a Massive Black Hole Outside the Milky Way
Discovery is the first detailed observation of the environs of a massive black hole outside the Milky Way, say researchers from the GRAVITY group. In…
ALMA Reveals Black Hole ‘Donuts’ Are Actually ‘Fountains’
Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive…
Scientists One Step Closer to Understanding Spiraling Black Holes
A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions…
Astronomers Reveal Cold Molecular Gas Pumped by a Black Hole
Most galaxies lie in clusters containing from a few to thousands of other galaxies. Our Milky Way, for example, belongs to the Local Group cluster…
ALMA Views Galaxy-Scale Fountain in Full Glory
A billion light-years from Earth lies one of the universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies…
GRAVITY Instrument Captures Observations of Material Orbiting Close to a Black Hole
ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky…
SOFIA Observations Reveal Possible Key to Black Hole Activity
Collimated jets provide astronomers with some of the most powerful evidence that a supermassive black hole lurks in the heart of most galaxies. Some of…
New Model Sheds Light on Spiraling Supermassive Black Holes
A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions…
Black Holes Only Contain Small Percentage of the Universe’s Dark Matter
For one brief shining moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe’s mysterious dark…
