Some supermassive black holes rapidly consume surrounding matter while simultaneously firing powerful streams of plasma into space at nearly the speed of light. However, this creates a physical puzzle: rapid feeding is expected to form a cold, flat accretion disk around the black hole, which prevents powerful jets from forming. https://phys.org/news/2026-10-hot-plasma-rapidly-black-holes.html Astronomy Tue, 20 Oct 2026 12:40:01 EDT news711711481 The gas orbiting Sagittarius A (Sgr A*), the supermassive black hole at the center of the Milky Way galaxy, is rich in metals, researchers at McGill University's Trottier Space Institute have found. The metal enrichment probably resulted from stars that exploded and released material into the black hole's surroundings over time, they said. https://phys.org/news/2026-10-webb-reveals-metal-rich-gas.html Astronomy Mon, 19 Oct 2026 16:00:15 EDT news711642481 A University of Missouri astronomer is leading a team of 130 researchers from 62 institutions—including NASA, the California Institute of Technology, Princeton University and Harvard University—on an ambitious mission to capture an unprecedented view of the early universe. https://phys.org/news/2026-10-astronomer-global-team-nasa-mission.html Astronomy Fri, 16 Oct 2026 19:20:01 EDT news711376043 Researchers have developed and tested a new locking method for gravitational wave detectors that will advance the discovery of distant black holes and neutron stars colliding. https://phys.org/news/2026-10-infrared-mirror-coating-obstacle-gravitational.html General Physics Fri, 16 Oct 2026 17:00:05 EDT news711373401 On May 10, 2025, a spacecraft built in the Soviet Union to land on Venus came home. Launched in 1972, Cosmos-482 was stranded by a failed upper stage of its rocket and circled Earth for 53 years. In its last days, several space agencies and research groups forecasted when it would fall, and therefore where. Roscosmos later reported that it came down in the Indian Ocean, west of Jakarta. https://phys.org/news/2026-10-air-deep-uncontrolled-satellites-rocket.html Space Exploration Fri, 16 Oct 2026 10:40:12 EDT news711280994 Astronomers have discovered a star being torn apart by a massive black hole more than 1,000 parsecs from the center of its host galaxy. The tidal disruption event, TDE 2023mfm, was first discovered by ZTF and then studied with a wide range of telescopes, including Keck, Lick, Hubble, Swift, Chandra, XMM-Newton and the VLA. The discovery paper was posted to the arXiv preprint server on Sept. 28. https://phys.org/news/2026-10-shredded-star-reveals-massive-black.html Astronomy Fri, 16 Oct 2026 09:20:17 EDT news711112932 Astronomers have used NASA's Chandra X-ray Observatory to break down the cause of a remarkable formation of radio waves they have nicknamed the "Treble Clef" because its distinct shape strongly resembles the musical symbol. https://phys.org/news/2026-10-chandra-treble-clef-galaxy-cluster.html Astronomy Thu, 15 Oct 2026 12:20:14 EDT news711283870 Astronomers have found two actively feeding supermassive black holes separated by just 175 parsecs (570 light-years) in a galaxy seen when the universe was only about 2 billion years old. The system, MG B2016+112, lies at a redshift of 3.273 and is the most compact dual AGN known at this redshift. The study was posted to the arXiv preprint server on Sept. 25. https://phys.org/news/2026-10-evidence-black-holes-parsecs-lurking.html Astronomy Wed, 14 Oct 2026 09:40:17 EDT news711113832 The James Webb Space Telescope (JWST) has detected a possible supernova in the early universe just days after the star exploded. Called AT 2026abck, the transient lies in a star-forming galaxy at a redshift of 5.017 and was found without the help of gravitational lensing. JWST observations suggest the event was caught only about four to 10 days after the explosion. The paper was posted to the arXiv preprint server on Sept. 29. https://phys.org/news/2026-10-webb-early-universe-supernova-days.html Astronomy Tue, 13 Oct 2026 10:50:01 EDT news711104454 Recent research shows that gravity and quantum information are deeply connected and that the shape of spacetime can be traced back to the way information is stored in quantum fields. https://phys.org/news/2026-10-gravity-quantum-linked-derivation-einstein.html General Physics Mon, 12 Oct 2026 19:20:01 EDT news711039286 Every black hole hides a question at its center. Einstein's theory predicts that whatever falls in is crushed into a singularity, a point of infinite density where the theory itself breaks down. Most physicists expect quantum gravity to replace that point with something finite. But the center lies hidden behind the horizon. How could we ever learn what is there? https://phys.org/news/2026-10-quantum-cores-fingerprints-black-holes.html General Physics Fri, 09 Oct 2026 17:40:01 EDT news710671667 Using data from the DESI Legacy Imaging Surveys, with help from artificial intelligence, an international team of scientists has discovered 70 new gravitational lenses—rare cosmic alignments that act as natural magnifying glasses. The new lenses further expand one of the largest collections of confirmed lenses to date and will allow scientists to study dark matter, galaxy evolution and the structure of the universe. https://phys.org/news/2026-10-largest-2d-universe-scientists-gravitational.html Astronomy Thu, 08 Oct 2026 09:40:12 EDT news710669701 Astronomers have confirmed a powerful radio galaxy from nearly 12.5 billion years ago. The source, TXS 2354+015, was originally identified as a high-redshift candidate from its characteristic drop in optical light, and follow-up spectroscopy placed it at a redshift of 4.946. Their paper was posted to the arXiv preprint server on Sept. 23. https://phys.org/news/2026-10-radio-galaxy-billion-years-powerful.html Astronomy Wed, 07 Oct 2026 15:40:10 EDT news710589777 Modern technological breakthroughs like lasers, MRI scanners, semiconductors and quantum computers rest on the study of quantum mechanics. However, the field has predominantly focused on (sub)atomic phenomena far removed from our human senses. https://phys.org/news/2026-10-quantum-shifting-centimeter-scale-lab.html General Physics Wed, 07 Oct 2026 14:00:50 EDT news710514722 Physicist Francis Halzen has an impressively long list of academic accolades—but every October, as the Nobel Prize rolled around, his failure to bag the biggest award of them all left him "miserable," he admits. https://phys.org/news/2026-10-nobel-winner-halzen-years-october.html General Physics Tue, 06 Oct 2026 21:00:01 EDT news710520383 Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst occurred at a redshift of 0.8577, and the activity lasted about 27 days in the burst's own rest frame—around 20 days longer than the previous record. The paper, posted to the arXiv preprint server on Sept. 18, explores different mechanisms that could be powering this puzzling burst. https://phys.org/news/2026-10-gamma-ray-stayed-month-previous.html Astronomy Tue, 06 Oct 2026 13:20:14 EDT news710505906 Earth seems like a troubled place right now, but at least our cosmic surroundings appear peaceful. This is not universally true, as explosions, collisions and other dangers lurk in other places and times. https://phys.org/news/2026-10-life-cosmos-universe-supercomputer-yields.html Astronomy Tue, 06 Oct 2026 10:40:29 EDT news710498341 Black holes, despite their extreme nature, are described by surprisingly few basic parameters: their mass, charge and spin. Two black holes may have formed for completely different reasons and passed through very different histories, yet still end up in the same final state. John Wheeler summarized this idea with the famous phrase "black holes have no hair." https://phys.org/news/2026-10-black-hole-disturbance-hawking.html General Physics Tue, 06 Oct 2026 10:00:01 EDT news710416753 Like Earth, most planetary bodies circle their star in stable, detached orbits. These companionable systems can suddenly change when a planet comes too close to its star. In such a close encounter, a star can pull the planet in and swallow it whole. https://phys.org/news/2026-10-astronomers-star-slowly-snacking-brown.html Astronomy Mon, 05 Oct 2026 16:40:16 EDT news710425861 Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's not the end of the weirdness. Their formation could have been even stranger if it occurred in a universe with a dark dimension, which is another theoretical construct. It posits that our space includes a hidden extra spatial dimension. https://phys.org/news/2026-10-tiny-ancient-black-holes-dimensional.html Astronomy Mon, 05 Oct 2026 12:40:16 EDT news710412892 In the early days of the universe, our home looked very different from how it does today. Back then, the region in our universe that would eventually become our Milky Way neighborhood was a collection of thousands of smaller galaxies—some pumping out tons of new stars, others filled only with gas or littered with dead stars and black holes. https://phys.org/news/2026-09-milky-begun-thousands-galaxies-simulations.html Astronomy Sat, 03 Oct 2026 09:00:07 EDT news710002132 Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 "bulgeless" galaxies—systems with little or no central stellar bulge. Their paper, published in Monthly Notices of the Royal Astronomical Society, suggests that galaxies without a central bulge grow black holes just as effectively as galaxies that have one—a surprising sign that black holes don't need galaxy mergers to grow normally. https://phys.org/news/2026-10-black-holes-quietly-galaxies-violent.html Astronomy Fri, 02 Oct 2026 15:20:02 EDT news710150297 Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied astrophysical objects. Some of these stars, known as pulsars, spin and send out beams of radio waves, making them appear to pulse as the beams sweep past Earth. https://phys.org/news/2026-09-astronomers-lowest-mass-neutron-star.html Astronomy Fri, 02 Oct 2026 08:20:08 EDT news709902345 On July 29, 2025, at 23:24 Universal Time, a long stretch of seafloor off Russia's Kamchatka Peninsula was thrust upward. The magnitude 8.8 earthquake was the largest on Earth since the Tohoku earthquake of 2011, according to the U.S. Geological Survey, and within minutes a tsunami was spreading across the Pacific. Warnings went out from Japan to Chile. On Shumshu, in the Kuril Islands, the water splashed up to about 19 meters (62 feet) high. https://phys.org/news/2026-09-kamchatka-tsunami-pacific-ten-hours.html Earth Sciences Thu, 01 Oct 2026 17:20:02 EDT news709910514 Researchers from The Australian National University (ANU) have engineered new optical coatings for LIGO, the global collaboration hunting gravitational waves from colliding black holes and neutron stars. https://phys.org/news/2026-10-ultra-precise-coatings-power-generation.html Astronomy Thu, 01 Oct 2026 14:40:18 EDT news710073602 The center of the Milky Way galaxy is a chaotic place. In addition to the 4-million-solar-mass black hole known as Sagittarius A* (Sgr A*), the region is full of gas, dust, strong magnetic fields and stars in various stages of life—from birth to death. https://phys.org/news/2026-10-cleaner-ray-view-galactic-center.html Astronomy Thu, 01 Oct 2026 10:20:32 EDT news710064541 Astronomers have identified what may be the first example of a new class of radio galaxy, one whose central black hole appears to have launched powerful jets on four separate occasions. High-resolution observations with the upgraded Giant Metrewave Radio Telescope (GMRT), combined with data from MeerKAT and the Very Large Array, reveal four pairs of radio structures arranged symmetrically around the central galaxy. https://phys.org/news/2026-09-astronomers-radio-galaxy-evidence-jet.html Astronomy Sun, 27 Sep 2026 10:20:05 EDT news709290029 Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas. Every large galaxy, including the Milky Way, is wrapped in a huge envelope of gas called the circumgalactic medium, or CGM. This reservoir of raw material stretches 10–20 times the size of the visible portion of the galaxy. https://phys.org/news/2026-09-black-hole-jets-galaxies-visible.html Astronomy Sat, 26 Sep 2026 17:00:01 EDT news709472146 Strike a bell, and it rings with a pitch and a fading that tell you about the bell: its size, its shape, the metal it is made of. Black holes ring too. When two merge, the newborn black hole shivers and sheds gravitational waves in a brief, dying chord, and since 2015, gravitational-wave detectors have been listening. The notes of that chord, which physicists call quasinormal modes, depend only on the black hole's mass and spin and on the law of gravity itself. Change the law, and the chord changes. https://phys.org/news/2026-09-higher-dimensional-black-holes-exact.html General Physics Thu, 24 Sep 2026 17:20:04 EDT news709463984 As a star nears the end of its life, it faces two very different fates: It can explode as a supernova, leaving behind a neutron star, or collapse and become a black hole. What determines the outcome remains one of astrophysics' great unanswered questions. https://phys.org/news/2026-09-supernova-black-hole-neutrino-flavor.html Astronomy Thu, 24 Sep 2026 12:20:08 EDT news709461185
