Gran Telescopio Canarias Finds the Farthest Black Hole That Belongs to a Rare Family of Galaxies

Astronomers have identified one of the rarest known classes of gamma-ray emitting galaxies, called BL Lacertae, within the first 2 billion years of ...

NASA's James Webb Telescopes Will Reveal Hidden Galaxies

Simulations show it's possible to distinguish host galaxy from quasars, although still challenging due to the galaxy's small size on the ...
Astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon, known as a tidal disruption event, is the closest ...

Weak Equivalence Principle Violated in Gravitational Waves

New research proves theoretically that the Weak Equivalence Principle can be violated by quantum particles in gravitational waves - the ripples in spacetime caused by colossal events such as merging ...

New Observations of Black Hole Devouring a Star Reveal Rapid Disk Formation

When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the ...

Spinning Black Hole Powers Jet by Magnetic Flux

A new letter has been found in the mysterious alphabet of black ...

Mystery Gas Discovered Near Center of Milky Way

Researchers have discovered a dense, cold gas that's been shot out from the center of the Milky Way 'like ...

Cosmic Gas Cloud Blinks in Sync With Circling Black Hole

Scientists have detected a mysterious gamma-ray heartbeat coming from a cosmic gas cloud. The inconspicuous cloud in the constellation Aquila is beating with the rhythm of a neighbouring precessing ...

'Black Dwarf Supernova': Physicist Calculates When the Last Supernova Ever Will Happen

New theoretical research finds that many white dwarfs may explode in supernova in the distant far future, long after everything else in the universe has died and gone ...

Unequal Neutron-Star Mergers Create Unique 'Bang' in Simulations

In a series of simulations, researchers determined that some neutron star collisions not only produce gravitational waves, but also electromagnetic radiation that should be detectable on ...

How Galaxies Die: New Insights Into the Quenching of Star Formation

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, ...

In a First, Astronomers Watch a Black Hole's Corona Disappear, Then Reappear

It seems the universe has an odd sense of humor. While a crown-encrusted virus has run roughshod over the world, another entirely different corona about 100 million light years from Earth has ...

Breakthrough in Deciphering Birth of Supermassive Black Holes

Scientists say they are closer to understanding how a supermassive black hole (SMBH) is born thanks to a new technique that has enabled them to zoom in on one of these enigmatic cosmic objects in ...

Scientists Propose Plan to Determine If Planet Nine Is a Primordial Black Hole

Scientists have developed a new method to find black holes in the outer solar system, and along with it, determine once-and-for-all the true nature of the hypothesized Planet ...

Hidden Sources of Mysterious Cosmic Neutrinos Seen on Earth

A new model points to the coronoe of supermassive black holes at the cores of active galaxies to help explain the excess neutrinos observed by the IceCube Neutrino ...

To Find Giant Black Holes, Start With Jupiter

On a quest to find the Universe's largest black holes, researchers identify the center of the solar system within 100 ...

Beacon from the Early Universe

Often described as cosmic lighthouses, quasars are luminous beacons that can be observed at the outskirts of the Universe, providing a rich topic of study for astronomers and cosmologists. Now ...

Monster Black Hole Found in the Early Universe

Astronomers have discovered the second-most distant quasar ever found. It is the first quasar to receive an indigenous Hawaiian name, Poniua'ena. Data show the supermassive black hole powering ...

Black Hole Collision May Have Exploded With Light

Astronomers have seen what appears to the first light ever detected from a black hole ...

New Research Hints at the Presence of Unconventional Galaxies Containing 2 Black Holes

Astronomers have identified periodic gamma-ray emissions from 11 active galaxies, paving the way for future studies of unconventional galaxies that might harbor two supermassive black holes at their ...

Quasar Jets Are Particle Accelerators Thousands of Light-Years Long

An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars is not concentrated in the region close to ...

Insight Into the Black Hole at the Center of Our Galaxy

Like most galaxies, the Milky Way hosts a supermassive black hole at its center. The object has captured astronomers' curiosity for decades. And now there is an effort to image it ...
