Cosmic Mass Monsters Clear the Way: Black Holes Help With Star Birth
The cosmic mass monsters clear the way for the formation of new suns in satellite galaxies. Research combining systematic observations with cosmological simulations has found…
Earliest Gigantic Black Hole Storm Ever Discovered – Supermassive Black Hole a Telltale Sign About Very Early History of the Universe
Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is…
Discovery of a Dying Supermassive Black Hole by Accident – Via a 3,000-Year-Long Light Echo
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…
Finding Quasars: Important but Extremely Rare Extragalactic Objects Are Now Easier to Spot
Astrophysicists have developed a new method for finding changing-looking quasars – important but extremely rare objects in deep space. Astrophysicists from the University of Bath…
World’s Most Powerful Telescopes Unite in Unprecedented Observations of Famous Black Hole
Scientists have coordinated observations of many of the world’s most powerful telescopes of the supermassive black hole in the galaxy M87. In April 2019, the…
Enormous Plasma Jets Reveal Monstrous Magnetic Fields Far, Far Away
Radio telescope images enable a new way to study magnetic fields in galaxy clusters millions of light years away. For the first time, researchers have…
Not All Theories Can Explain the Gargantuan Black Hole M87*

Violent Black Hole-Neutron Star Collisions May Help Settle Dispute Over Universe’s Expansion
Studying the violent collisions of black holes and neutron stars may soon provide a new measurement of the Universe’s expansion rate, helping to resolve a…
Testing Einstein’s Theory of General Relativity From the Shadows and Collisions of Black Holes
General relativity, Einstein’s theory of gravity, is best tested at its most extreme — close to the event horizon of a black hole. This regime…
Supermassive Black Holes Like to Eat, but Have a Variety of Table Manners
All supermassive black holes in the centers of galaxies appear to have periods when they swallow matter from their close surroundings. But that is about…
“The Unicorn” – Closest Black Hole to Earth Ever Discovered
Astronomers dub it “The Unicorn,” call it something special. Scientists have discovered one of the smallest black holes on record – and the closest one…
