The first-ever photo of a supermassive black hole has gotten a “maximum resolution” makeover, thanks to artificial intelligence (AI).
The iconic 2019 image of M87*, a solar system-size black hole in the center of the Virgo galaxy cluster, was made by pooling radio light that had traveled to us across 53 million light-years of space.
Now, a new effort has used machine learning to clean the image, sharpening it to achieve the fullest resolution possible and exposing a larger and darker central region surrounded by glowing gas that astronomers have described as a “skinny donut.” The researchers published the updated image April 13 in The Astrophysical Journal Letters (opens in new tab) .

“With our new machine learning technique, PRIMO, we were able to achieve the maximum resolution of the current [telescope] array,” lead author Lia Medeiros (opens in new tab) , an astronomer at the Institute for Advanced Study in Princeton, New Jersey, said in a statement. “Since we cannot study black holes up-close, the detail of an image plays a critical role in our ability to understand its behavior. The width of the ring in the image is now smaller by about a factor of two, which will be a powerful constraint for our theoretical models and tests of gravity.”
The Messier 87 black hole, which is as wide as our solar system and 6.5 billion times the mass of the sun, was imaged by the Event Horizon Telescope (EHT), an array of eight globally synchronized radio telescopes. Black holes have such a powerful gravitational pull that nothing (not even light) can escape their maws, but this doesn’t mean they can’t be seen. This is because active black holes are surrounded by accretion disks — vast rings of material stripped from gas clouds and stars orbiting the black holes’ event horizons — that get heated to red-hot temperatures by friction, producing a faint-yet-detectable glow.

It is from these faint radio glimmers that astronomers were able to reconstruct the distant singularity as a doughnut hole surrounded by a halo of light. But gaps in the data, arising from missing jigsaw pieces of light where no radio telescope was there to receive it, left the image fuzzy and ill-defined.
To sharpen the picture, the researchers turned to a new AI technique called principal-component interferometric modeling (PRIMO), which analyzed more than 30,000 high-fidelity simulated images of black hole gas accretions to find common patterns. These patterns were then sorted by how commonly they occurred before being blended together and applied to the original image to produce a sharper estimate.
By checking the newly rendered image with EHT data and the theory on what the black hole should look like, the researchers confirmed that their image was a very close approximation of the real thing. This obviously required the big assumption that the black hole will look like we expect it to, but the researchers said the 2019 image already confirmed theoretical predictions of its broad details. This new image will enable even closer study of the extreme effects produced by the cosmic sinkholes, where our theories of gravity and quantum mechanics break down and merge, the team added.
“The 2019 image was just the beginning,” Medeiros said. “If a picture is worth a thousand words, the data underlying that image have many more stories to tell. PRIMO will continue to be a critical tool in extracting such insights.”
Donald Trump says he has ordered two nuclear submarines to be positioned in the “appropriate regions” in a row with former Russian president Dmitry Medvedev.
It comes after Mr Medvedev, who is now deputy chair of Russia‘s Security Council, told the US president on Thursday to remember Moscow had Soviet-era nuclear strike capabilities of last resort.
On Friday, Mr Trump wrote on social media: “Based on the highly provocative statements of the Former President of Russia, Dmitry Medvedev, who is now the Deputy Chairman of the Security Council of the Russian Federation, I have ordered two Nuclear Submarines to be positioned in the appropriate regions, just in case these foolish and inflammatory statements are more than just that.
“Words are very important, and can often lead to unintended consequences, I hope this will not be one of those instances. Thank you for your attention to this matter!”

Trump: ‘We’re going to protect our people’
Speaking outside the White House later in the day, Mr Trump was asked about why he had moved the submarines and replied: “We had to do that. We just have to be careful.
“A threat was made and we didn’t think it was appropriate, so I have to be very careful. So I do that on the basis of safety for our people. A threat was made by a former president of Russia and we’re going to protect our people.”
The spat between Mr Trump and Mr Medvedev came after the US president warned Russia on Tuesday it had “10 days from today” to agree to a ceasefire in Ukraine or face tariffs, along with its oil buyers.
Moscow has shown no sign that it will agree to Mr Trump’s demands.
Trump’s move appears to signal a significant deterioration in relationship with Putin
Normally it’s Moscow rattling the nuclear sabres, but this time it’s Washington in what marks a dramatic escalation in Donald Trump’s war of words with the former Russian president Dmitry Medvedev.
More importantly, it appears to signal a significant deterioration in his relationship with Vladimir Putin.
The US president’s patience with the Kremlin was already at its thinnest earlier this week, when he shrank his deadline for progress towards a peace deal from 50 days to 10.
But Russia’s lack of outward concern with this stricter ultimatum – which has swung from dismissive to (in Medvedev’s case) insulting – seems to have flicked a switch.
For this is the first time Trump’s pressure on Moscow has amounted to anything more than words.
We don’t know where the subs are, or how far they had to move to get closer to Russia, but it’s an act that sits several rungs higher than the usual verbal threats to impose sanctions.
How will Russia respond? I’m not sure Vladimir Putin has ever caved to an ultimatum and I doubt he’ll start now.
But I don’t think he’ll want the situation to deteriorate further. So I suspect he’ll make another offer to the US, that’s dressed up as a concession, but in reality may prove to be anything but.
It’s a tactic that’s worked before, but the stakes have suddenly got higher.
On Thursday, Mr Medvedev reminded Mr Trump that Russia possessed a Soviet-era automated nuclear retaliatory system – or “dead hand”.
Mr Medvedev, a close ally of Russian President Vladimir Putin, was referring to a secretive semi-automated Soviet command system designed to launch Russia’s missiles if its leadership was taken out in a decapitating strike.
He made the remarks after Mr Trump told him to “watch his words” after Mr Medvedev said the US president’s threat of hitting Russia and its oil buyers with punitive tariffs was “a game of ultimatums” and added that “each new ultimatum is a threat and a step towards war” between Russia and the US.

Mr Medvedev served as Russia’s president from 2008 and 2012, when Mr Putin was barred from seeking a third consecutive term, but then stepped aside to let him run again.
As deputy chair of Russia’s Security Council, he has become known for his provocative and inflammatory statements since Moscow invaded Ukraine in 2022.
Donald Trump has said “nobody has asked” him to pardon Ghislaine Maxwell, but insisted he has “the right to do it” as US president.
Jeffrey Epstein’s former girlfriend is currently serving a 20-year sentence after being convicted of helping the paedophile financier traffic and sexually abuse underage girls in 2021.
Prosecutors have said Epstein’s sex crimes could not have been done without Maxwell, but her lawyers have maintained that she was wrongly prosecuted and denied a fair trial, and have floated the idea of a pardon from Mr Trump.
Last week, they asked the US Supreme Court to take up her case.
When pressed on the possibility of pardoning Maxwell, Mr Trump told reporters: “I’m allowed to do it, but nobody’s asked me to do it.”
He continued: “I know nothing about it. I don’t know anything about the case, but I know I have the right to do it. I have the right to give pardons, I’ve given pardons to people before, but nobody’s even asked me to do it.”
Mr Trump also said he would not pardon Sean “Diddy” Combs, who was convicted in July on two charges of transportation to engage in prostitution.

Trump ‘never visited Espstein island’
His comments came shortly after the federal Bureau of Prisons (BOP) said Maxwell has been moved to a minimum-security prison camp in Texas.
She was being held at a low-security prison in Tallahassee, Florida, that housed men and women, but has now been transferred to a prison camp in Bryan, Texas.
When asked why Maxwell was transferred, BOP spokesperson Donald Murphy said he could not comment on the specifics, but that the BOP determines where inmates are sent based on such factors as “the level of security and supervision the inmate requires”.
Maxwell’s lawyer confirmed the move but also declined to discuss the specific reasons for it.
The Texas camp houses solely female prisoners, the majority of whom are serving time for nonviolent offences and white-collar crimes, Sky’s US partner NBC News reports.

Minimum-security federal prison camps house inmates considered to be the lowest security risk and some facilities do not even have fences.
A senior administration official told NBC: “Any false assertion this individual was given preferential treatment is absurd.
“Prisoners are routinely moved in some instances due to significant safety and danger concerns.”
Maxwell has received renewed attention in recent weeks, after the US Justice Department said it would not be releasing the so-called ‘Epstein files’.
The department said a review of the Epstein case had found “no incriminating ‘client list'” and “no credible evidence” the jailed financier – who killed himself in prison in 2019 – had blackmailed famous men.
Officials from the Trump administration have since tried to cast themselves as promoting transparency in the case.
Last month, they lodged a request to unseal grand jury transcripts – which was denied – and Maxwell was last week interviewed by Deputy Attorney General Todd Blanche.
Epstein survivor’s family criticises move
Maxwell’s move to a lower security facility has been criticised by the family of Epstein abuse survivor Virginia Giuffre, who died in April, and accusers Annie and Maria Farmer.
They said in a statement: “It is with horror and outrage that we object to the preferential treatment convicted sex trafficker Ghislaine Maxwell has received.
“Ghislaine Maxwell is a sexual predator who physically assaulted minor children on multiple occasions, and she should never be shown any leniency.
“Yet, without any notification to the Maxwell victims, the government overnight has moved Maxwell to a minimum security luxury prison in Texas.”
The statement concluded: “This move smacks of a cover up. The victims deserve better.”
Recently, Australia has launched its first Eris Rocket Skyward; however, in no time, it didn’t get very far. But the history has been recorded in the books. The country has launched its own orbital that was entirely crafted within the country. The company Gilmour Space achieved the milestone on July 29th, 2025, when it sent its first Eris rocket into the sky. It took the flight from the Bowen Orbital Spaceport in coastal Queensland at 6:35 p.m. EDT (8:30 am local time in Australia).
How Did The Failure Occur?
As the liftoff commenced, the Eris couldn’t get far, and the rocket began to slide sideways. It soon rose off the pad and within a span of 14 seconds, crashed back to the Earth. This crash was best compared with that of the third orbital launch attempt enforced by Astra (California) in the year 2021. Although Gilmour Space was not entirely relying on the success.
Dating back to February, the Gilmour company stated, “Whether we make it off the pad, reach max Q, or get all the way to space, what’s important is that every second of the flight will deliver valuable data that will improve our rocket’s reliability and performance for future launches”. Significantly, post-launch, they issued a statement narrating that it is a big step for launch and that they have their eyes on it. Also, there were no injuries reported or other environmental impacts during the launch.
Behind the Scenes of Orbital Launch: The Plans and Execution
The orbital launch, which occurred on July 29th, 2025, was previously aimed to be executed in May; however, due to Tropical Cyclone Alfred, the Gilmour Space had to postpone it. Soon after the cyclone cleared, the company targeted the launch in mid-May, but could not proceed due to a technical issue, where the rocket’s payload fairing failed suddenly. As stated by Gilmour Space, the issue was caused due to a power surge.
After fixing the technical issues, the company again planned the launch for June. But, as Gilmour Space operates north of the town of Bowen, the winds did not fit well, and due to unfavourable weather, the launch was rescheduled for later. Finally, in July, it went off air.
To Conclude
Gilmour Space was founded by Adam Gilmour and James Gilmour. This brother duo aims to reach heights in the area of spaceflight. Not only is Eris their focus, but they have also invented satellites. The launch was a big attempt for the country, and such advancement was a big breakthrough in over 50 years.
