Black Hole Space Volcano Erupts After 100 Million Year Nap
Overview: A Dormant Giant Reawakens In a striking turn of cosmic events, a supermassive black hole nestled within a distant galaxy cluster has bursts of activity after an astonishing 100 million-year slumber. Researchers describe the renewed energy as a dramatic “eruption” of material and jets, offering a rare glimpse into how these titanic engines switch…

What are dark stars? How they could solve three cosmic mysteries
What are dark stars? Dark stars are a theoretical idea proposed to explain how the first generations of luminous objects in the universe formed during cosmic dawn. Unlike ordinary stars powered by nuclear fusion, these hypothetical stars would be energized in part by the annihilation of dark matter particles in their cores. This extra energy…

Dark Stars: A Cut-Above Theory Explaining 3 Cosmic Dawn Mysteries
What are dark stars? Dark stars are a theoretical type of early star that could ignite not only by nuclear fusion but also with a glow powered by dark matter. In some models, pairs of dark matter particles annihilate inside a forming star, releasing heat that sustains luminosity even as ordinary fuel wavers. While not…

Dark Stars: Could They Explain Three Cosmic Mysteries Revealed by JWST
What Are Dark Stars? Dark stars are a theoretical type of stellar object that could have formed in the early universe. Unlike ordinary stars powered by nuclear fusion, dark stars are hypothesized to glow faintly because they draw energy from the annihilation of dark matter particles, or through alternative energy sources linked to the surrounding…

Astronomers Capture a Twisted Dance of Two Supermassive Black Holes and Unseen Jet Behavior
Overview: A cosmic waltz at the edge of a galaxy In a landmark observation, scientists using the Event Horizon Telescope (EHT) have captured evidence of a dramatic interaction between what appears to be two supermassive black holes at the center of a distant galaxy. The data reveal a violent, energy-packed dance — a gravitational ballet…

Astronomers Unveil Twisted Dance of Two Supermassive Black Holes and Unprecedented Jet Behavior
Two Supermassive Black Holes in a Cosmic Waltz In a discovery that reads like a science fiction epic written in the language of light, astronomers using the Event Horizon Telescope (EHT) have imaged what appears to be a rare interaction between two supermassive black holes (SMBHs) at the core of a distant galaxy. The data…

A Cosmic Pas de Deux: Two Supermassive Black Holes in a Twisted Jet Dance
Global telescope catches unprecedented dance between titanic black holes In a landmark observation, astronomers using the Event Horizon Telescope (EHT) have captured compelling evidence of a pair of supermassive black holes locked in a violent, choreographed encounter at the center of a distant galaxy. The data show a strikingly twisted arrangement of relativistic jets and…

Supermassive Black Holes Exhibit Selective Feeding During Galaxy Mergers
Overview: A New Look at Black Hole Diets For decades, astronomers have treated supermassive black holes (SMBHs) as cosmic vacuum cleaners, voraciously consuming gas, stars, and anything that crosses their event horizons. Yet recent observations with the Atacama Large Millimeter/submillimeter Array (ALMA) are challenging that image. In merging galaxies, SMBHs show selective feeding patterns that…

Selective Feeding: How Supermassive Black Holes Skim Gas During Galaxy Mergers
Introduction: A New View of Black Hole Feeding Black holes are often portrayed as cosmic vacuum cleaners, devouring anything that strays too close. Yet recent observations with the Atacama Large Millimeter/submillimeter Array (ALMA) show that supermassive black holes (SMBHs) in merging galaxies do not always gorge on available gas. Instead, their appetite appears selective, channelling…

Supermassive Black Holes Feed Selectively During Galaxy Mergers
Introduction: A Surprising Appetite Black holes are famed for their voracious appetites, devouring matter that strays too close. But new observations from the Atacama Large Millimeter/submillimeter Array (ALMA) reveal a more nuanced behavior, even for the universe’s most massive beasts. During galaxy mergers, supermassive black holes (SMBHs) appear to eat selectively, preferentially accreting certain streams…
