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 ...

Mystery Astronomical Object in 'Mass Gap': Neutron Star? Black Hole?

Researchers have discovered what is either the heaviest known neutron star, or the lightest black ...

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 ...

Ultra-Bright X-Ray Source Awakens Near a Galaxy Not So Far Away

A new ultra-bright source of X-rays has awakened in between our galactic neighbors the Magellanic Clouds, after a 26-year slumber. This is the second-closest such object known to date, with a ...

Large Simulation Finds New Origin of Supermassive Black Holes

Computer simulations conducted by astrophysicists have revealed a new theory for the origin of supermassive black holes. In this theory, the precursors of supermassive black holes grow by swallowing ...

Under Pressure, Black Holes Feast

A new study shows that some supermassive black holes actually thrive under pressure. It has been known for some time that when distant galaxies -- and the supermassive black holes within their cores ...

ALMA Spots Twinkling Heart of the Milky Way

Astronomers have found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team interpreted these blinks to be due to the rotation of radio spots ...

Like Thunder Without Lightning

Mergers between black holes and neutron stars in dense star clusters are quite unlike those that form in isolated regions where stars are few. Their associated features could be crucial to the study ...
