The biggest black hole breakthroughs of 2025
2025 was another big year for black holes, and here's our pick of the top black hole stories from the last twelve months.
Mysterious bright blue cosmic blasts triggered by black holes shredding stars, scientists say. ‘It’s definitely not just an exploding star.’
"The sheer amount of radiated energy from these bursts is so large that you can't power them with a core collapse stellar explosion — or any other type of normal stellar explosion."
James Webb Space Telescope confirms 1st ‘runaway’ supermassive black hole rocketing through home galaxy at 2.2 million mph: ‘It boggles the mind!’
"The forces that are needed to dislodge such a massive black hole from its home are enormous."
Einstein’s right again! Scientists catch a feasting black hole dragging the very fabric of spacetime
"This is a real gift for physicists as we confirm predictions made more than a century ago."
This 7-hour cosmic explosion is the longest gamma-ray burst ever seen. Could it be from an elusive class of black hole?
"This is certainly an outburst unlike any other we've seen in the past 50 years."
This supermassive black hole flung out matter at 134 million mph: ‘On a scale almost too big to imagine’
In other words, the matter traveled at 20% the speed of light.
Scientists discover 53 powerful quasars shooting out jets up to 50 times wider than our Milky Way
"The sizes of these radio jets are not comparable to our solar system or even our galaxy."
NASA exoplanet-hunting spacecraft hears a red giant star ‘singing’ to its partner black hole
NASA's exoplanet-hunting spacecraft TESS has heard the song a star-quaking red giant sings to its partner black hole.
Have gravitational waves provided the first hint of primordial black holes born during the Big Bang?
Scientists may have "heard" the first tantalizing evidence of primordial black holes formed directly from overly dense pockets of matter just after the Big Bang.
James Webb Space Telescope watches our Milky Way galaxy’s monster black hole fire out a flare
Observations of the supermassive black hole at the heart of the Milky Way, Sagittarius A*, collected by the James Webb Space Telescope, have allowed scientists to better understand how this cosmic titan fires off flares.
