Can black holes turn into white holes? It's not such a crazy idea, scientists say
Can black holes turn into white holes? It's not such a crazy idea, scientists say "We found that the lifetime of black holes is much longer than previously thought." New research suggests that black holes born during the Big Bang could live much longer than previously estimated.
Violating the 3rd law of black hole mechanics in vacuum gravity
June 3, 2026 feature Violating the 3rd law of black hole mechanics in vacuum gravity Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts that black holes obey a set of rules, known as the laws of black hole mechanics. These rules somewhat...
Hidden supermassive black hole pairs may finally have a visible signal
Hidden supermassive black hole pairs may finally have a visible signal - Date: - June 5, 2026 - Source: - University of Oxford - Summary: - Scientists have proposed a new method for finding tightly bound supermassive black hole pairs by searching for stars that flash repeatedly as their light is magnified by the black holes’ gravity. The timing and brightness of these bursts could provide a unique fingerprint of black holes slowly spiraling toward a future collision. Astronomers from the...
JWST 'weighs' dormant black hole 10 billion light-years away
JWST 'weighs' dormant black hole 10 billion light-years away Sadie Harley Scientific Editor Robert Egan Associate Editor The most distant, nearly invisible dormant black hole has been detected and "weighed" by an international team of astronomers that includes researchers from UCL. The study, published in Science, identified a dormant black hole at the heart of a galaxy known as MRG-M0138 located over 10 billion light years away. It is the most distant dormant black hole yet detected, 15...
Astronomers discover a 'lost world' of black hole mergers: 'It's the astronomical equivalent of uncovering an ancient civilization'
Astronomers discover a 'lost world' of black hole mergers: 'It's the astronomical equivalent of uncovering an ancient civilization' "Now, we have growing evidence that there are ways that the universe creates merging black holes in addition to those that come from massive binary stars." Astronomers have struck "black gold" — a treasure trove of black hole mergers. And the discovery was made by analyzing ripples in the very fabric of space and time, or spacetime, called gravitational waves.
James Webb Space Telescope weighs 'sleeping giant' black hole from 10 billion light-years away — and it's 6 billion times our sun's mass
James Webb Space Telescope weighs 'sleeping giant' black hole from 10 billion light-years away — and it's 6 billion times our sun's mass "We can now undertake a more complete census of how black holes develop over time and infer their role in shaping galaxy evolution." Using the James Webb Space Telescope (JWST), astronomers have "weighed" a sleeping giant — a dormant supermassive black hole located a staggering 10 billion light-years away. That makes this black hole the most distant...
James Webb telescope detects most distant dormant black hole, invisible in all wavelengths and weighing as much as 6 billion suns
James Webb telescope detects most distant dormant black hole, invisible in all wavelengths and weighing as much as 6 billion suns JWST found a black hole hiding in a galaxy more than 10 billion light-years away from Earth, and used a cosmic magnifying glass to determine its mass. The James Webb Space Telescope has spotted the most distant, dormant black hole in the known universe , hiding in a galaxy more than 10 billion light-years from Earth. The newly analyzed black hole, located in a...
Milky Way black hole's missing wind finally found after a half-century-long search
Milky Way black hole's missing wind finally found after a half-century-long search Sadie Harley Scientific Editor Robert Egan Associate Editor After more than 50 years of searching, astrophysicists at Northwestern University have finally discovered evidence of a powerful wind blowing from the Milky Way's central supermassive black hole, Sagittarius A* (Sgr A*). According to theoretical physics and a long-accepted understanding of galaxies' evolution, as black holes consume materials, they...
Record ultraviolet quasar wind reaches 30% light speed near supermassive black hole
Record ultraviolet quasar wind reaches 30% light speed near supermassive black hole Gaby Clark Scientific Editor Robert Egan Associate Editor A team led by York University researchers has discovered the fastest wind near a supermassive black hole ever found at ultraviolet wavelengths, driven by the disk of matter (quasar) surrounding the black hole. "This quasar has a black hole of 1.7 billion times the mass of the sun. What's not typical is that it has gas moving towards us at 30% of the...
Scientists find wind blowing from our Milky Way's black hole after half-century search: 'There it is'
Scientists find wind blowing from our Milky Way's black hole after half-century search: 'There it is' "There is the thing that everybody’s been looking for for 50 years." After searching for 50 years, astronomers have finally discovered evidence of powerful winds blowing from Sagittarius A* (Sgr A*), the supermassive black hole at the heart of our galaxy. The discovery represents a deepening of our understanding of the physics at play both around supermassive black holes and at the heart of...
