Astronomers Discover Class of Strange Objects Near Our Galaxy's Enormous Black Hole

Astronomers have discovered a new class of bizarre objects at the center of our galaxy, not far from the supermassive black hole called Sagittarius ... read more

Astronomers Find Wandering Massive Black Holes in Dwarf Galaxies

Studies with the VLA indicate that roughly half of the massive black holes in dwarf galaxies are not in the centers of those galaxies. This gives astronomers new insights into the conditions in which ... read more

ESO Observations Reveal Black Holes' Breakfast at the Cosmic Dawn

Astronomers have observed reservoirs of cool gas around some of the earliest galaxies in the universe. These gas halos are the perfect food for supermassive black holes at the center of these ... read more

Planet-Mass Objects in Extragalactic Systems

A research group is reporting the detection of extragalactic planet-mass objects in a second and third galaxy beyond the Milky Way after the first detection in 2018. With the existing observational ... read more

A Runaway Star Ejected from the Galactic Heart of Darkness

Astronomers have spotted an ultrafast star, traveling at a blistering 6 million km/h, that was ejected by the supermassive black hole at the heart at the Milky Way five million years ago. The ... read more

'Pac-Man-Like' Mergers Could Explain Massive, Spinning Black Holes

Scientists have reported detecting gravitational waves from 10 black hole mergers to date, but they are still trying to explain the origins of those mergers. The largest merger detected so far seems ... read more

Scientists May Have Discovered Whole New Class of Black Holes

New research shows that astronomers' search for black holes might have been missing an entire class of black holes that they didn't know existed. Astronomers offer a new way to search for ... read more

How to Spot a Wormhole (If They Exist)

Whether wormholes exist is up for debate. But in a recent article, physicists describe a technique for detecting these ... read more

Stormy Cluster Weather Could Unleash Black Hole Power and Explain Lack of Cosmic Cooling

'Weather' in clusters of galaxies may explain a longstanding puzzle. Scientists have now used sophisticated simulations to show how powerful jets from supermassive black holes are disrupted ... read more

Going Against the Flow Around a Supermassive Black Hole

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array ... read more

Black Holes Stunt Growth of Dwarf Galaxies

Astronomers have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star ... read more

Not Long Ago, the Center of the Milky Way Exploded

A titanic, expanding beam of energy sprang from close to the supermassive black hole in the center of the Milky Way just 3.5 million years ago, sending a cone-shaped burst of radiation through both ... read more

Massive Filaments Fuel the Growth of Galaxies and Supermassive Black Holes

Based on direct observations researchers have discovered massive filaments between galaxies in a proto-cluster, extending over more than 1 million parsecs and providing the fuel for intense formation ... read more

Black Holes and Their Host Galaxies, Growing Old Together

The 'special relationship' between supermassive black holes (SMBHs) and their hosts -- something astronomers and physicists have observed for quite a while -- can now be understood as a ... read more

Scientists Watch a Black Hole Shredding a Star

A satellite searching space for new planets gave astronomers an unexpected glimpse at a black hole ripping a star to shreds. The milestone was reached with the help of a worldwide network of robotic ... read more

A Black Hole's Warped World

A new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if viewed in a funhouse ... read more

Six Galaxies Undergoing Sudden, Dramatic Transitions

Astronomers observed six mild-mannered LINER galaxies suddenly and surprisingly transforming into ravenous quasars -- home to the brightest of all active galactic nuclei. The team's observations ... read more

Most Massive Neutron Star Ever Detected, Almost Too Massive to Exist

Astronomers have discovered the most massive neutron star to date, a rapidly spinning pulsar approximately 4,600 light-years from Earth. This record-breaking object is teetering on the edge of ... read more

Black Hole at the Center of Our Galaxy Appears to Be Getting Hungrier

The enormous black hole at the center of our galaxy is having an unusually large meal, and researchers don't know why. 'We have never seen anything like this in the 24 years we have studied ... read more

Towering Balloon-Like Features Discovered Near Center of Milky Way

Astronomers have discovered one of the largest features ever observed in the center of the Milky Way: a pair of enormous radio-emitting bubbles that tower hundreds of light-years above and below the ... read more

Scientists Detect the Ringing of a Newborn Black Hole for the First Time

Physicists have 'heard' the ringing of an infant black hole for the first time, and found that the pattern of this ringing does, in fact, predict the black hole's mass and spin -- more ... read more

Are Black Holes Made of Dark Energy?

Researchers have identified and corrected a subtle error that was made when applying Einstein's equations to model the growth of the ... read more

Astronomers Find a Golden Glow from a Distant Stellar Collision

Astronomers have re-examined data from a gamma-ray burst spotted in August 2016 and found new evidence for a kilonova -- a turbocharged explosion that instantly forged several hundred planets' ... read more

Black Hole Holograms

Researchers show how a holographic tabletop experiment can be used to simulate the physics of a black hole. This work may lead the way to a more complete theory of quantum gravity that harmonizes ... read more
