Astronomers have uncovered a rare, decades-long flare from the Perseus Cluster’s central black hole, finally solving a mystery hidden in years of data. Astronomers tracking the behavior of a supermassive black hole at the heart of the Perseus Cluster...

New JWST observations of mysterious little red dots suggest massive black holes may have formed and grown before their host galaxies even took shape. The James Webb Space Telescope (JWST) has shed new light on one of the most puzzling phenomena in the...

By merging dual acoustic black hole profiles with a unique vibration mode conversion architecture, scientists have engineered a compact ultrasonic radiator with dramatically amplified sound pressure and superior energy focusing. Acoustic technologies...

quasars that formed when the cosmos was only about 670 million years old, pushing the frontier of observable supermassive black holes back to a time when the universe was just 5 % of its current age. The results, now appearing in Astronomy and...

have identified a elusive population of 12 “fossil” galaxies where the massive jets powered by central supermassive black holes have finally gone dark. By analyzing these cosmic remnants, researchers have uncovered a younger, more transient class of...

New observations from DESI and LOFAR reveal supermassive black holes leave glowing trails of ionized gas that extend far beyond their host galaxies. Supermassive black holes are known to exert influence far beyond the galactic centers they occupy, yet...

Astronomers have discovered S301, a star orbiting Sagittarius A* at 8.5% the speed of light, offering a unique new way to measure the black hole’s spin. Astronomers have identified a new stellar resident in the immediate vicinity of the Milky Way’s...

to reconcile the observed number of supernovas with the number of massive stars that appear to simply vanish into black holes. This latest study suggests that the missing piece of the puzzle lies in the intersection of particle physics and stellar...

where a system exists at the razor-thin margin between stability and total gravitational breakdown. While the massive black holes associated with galactic centers or stellar deaths are well-documented, these proposed microscopic structures remain a...

may end their lifecycle as white dwarfs, whereas those surpassing it are likely to collapse further into neutron stars or black holes, or explode in supernovae. Applications of the Chandrasekhar Limit in Astrophysics The application of the Chandrasekhar...

Euclid discovers 31 ancient quasars, including two from 670 million years after the Big Bang, shedding light on early black holes and galaxy formation. The ESA Euclid mission has added 31 previously unknown quasars to the cosmic record, among them two...

surveys. Why Lensed Quasars Matter Quasars shine as some of the brightest beacons in the cosmos, powered by supermassive black holes devouring surrounding gas. When a massive foreground galaxy bends the light from a more distant quasar, the resulting...

billion years old. Blazars represent some of the most energetic phenomena in the cosmos. They are fueled by supermassive black holes that actively consume surrounding gas and dust. During this process, a fraction of that matter is accelerated into jets...

Sensitive near-infrared observations uncover widespread neutral winds that expel cold gas from massive galaxies, finally linking black hole activity to the end of star formation. Unraveling the mechanisms that cause massive galaxies to halt their star...

Nearly 900 astronomers are gearing up to use NASA’s Roman Space Telescope to hunt for hidden planets, black holes, and breakthrough cosmic discoveries. NASA’s Nancy Grace Roman Space Telescope, which successfully reached its operational zone near the...

Scientists build a lab setup mimicking black‑hole energy extraction, using a time‑modulated device that boosts electromagnetic waves. A team at the CUNY Graduate Center has demonstrated a laboratory technique that mimics the exotic energy‑extraction...

observations suggest that mysterious, ancient cosmic objects may actually be compact galaxies hiding around supermassive black holes. Astronomers have uncovered compelling evidence that the enigmatic “little red dots” observed in the early universe are...

A strange optical illusion makes people see a black hole grow larger, but not everyone experiences it the same way. Scientists are still puzzled. Psychologists have been investigating a powerful optical effect known as the “expanding hole” illusion....

a prominent central bar or bridge of stars that channels gas toward its core. Chandra X-rays (purple) highlight growing black holes along the bar and core, merged with Hubble optical light (white, yellow and soft blue) and JWST infrared dust filaments...

of current and future detectors. Such pragmatic innovations may help the field capture weaker signals from distant black holes, neutron stars, and other extreme astrophysical phenomena.
