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.
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...
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...
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.
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...
Strange 'spacetime crystals' could give birth to tiny black holes
Strange 'spacetime crystals' could give birth to tiny black holes "Sometimes a tiny, seemingly insignificant cause is enough to trigger a huge and dramatic change." When we think about a black hole, we probably picture some vast cosmic titan, greedily consuming any matter unfortunate enough to fall within its gravitational influence. Thinking deeper, we probably imagine this ravenous cosmic beast forming from the explosive collapse of the core of a massive star.
Wind from Milky Way's supermassive black hole is finally discovered
Wind from Milky Way's supermassive black hole is finally discovered WASHINGTON, June 5 : After five decades of trying, astronomers have finally discovered the wind emanating from the supermassive black hole at the center of our Milky Way galaxy, though it turns out it is more of a gentle breeze than a hurricane. Using data from the Chile-based ALMA telescope and NASA's orbiting Chandra X-ray Observatory, the researchers viewed the cosmic neighborhood around the black hole - called...
These record-breaking black hole winds could create a category 79 hurricane on Earth
These record-breaking black hole winds could create a category 79 hurricane on Earth "This wind is unlike anything on Earth." Astronomers have discovered a distant quasar — or active nucleus of a galaxy — that's powered by a feeding supermassive black hole blasting out winds at record-breaking speeds of 30% the speed of light, around 201 million miles (323 million kilometers) per hour. This is the fastest black hole wind seen specifically in ultraviolet wavelengths.
Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy
June 2, 2026 report Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy Shreejaya Karantha Author Sadie Harley Scientific Editor Robert Egan Associate Editor Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study was posted to the preprint server arXiv on May 18.
