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.”

‘Return hubs’ get UN backing in boost for potential plans to deport failed asylum seekers

'Return hubs' get UN backing in boost for potential plans to deport failed asylum seekers

“Return hubs” that would see Britain send failed asylum seekers to another country have been endorsed by the UN’s refugee agency.

There have been reports that Sir Keir Starmer’s government is looking into deporting illegal migrants to the Balkans.

According to The Times, Home Secretary Yvette Cooper met the UN’s high commissioner for refugees last month to discuss the idea.

It would see the government pay countries in the Balkans to take failed asylum seekers – a prospect ministers hope might discourage people from crossing the Channel in small boats.

A total of 9,099 migrants have made that journey so far this year, including more than 700 on Tuesday this week – the highest number on a single day in 2025.

One migrant died while trying to make the crossing on Friday.

The UN’s refugee agency has set out how such hubs could work while meeting its legal standards in a document published earlier this week.

It recommended monitoring the hubs to make sure human rights standards are “reliably met”.

The country hosting the return hub would need to grant temporary legal status for migrants, and the country sending the failed asylum seekers would need to support it to make sure there are “adequate accommodation and reception arrangements”.

A UK government source said it was a helpful intervention that could make the legal pathway to some form of return hub model smoother.

It comes after the EU Commission proposed allowing EU members to set up so-called “return hubs” abroad, with member state Italy having already started sending illegal migrants abroad.

It sends people with no right to remain to Italian-run detention centres in Albania, something Sir Keir has taken an interest in since coming to power.

With Reform UK leading Labour in several opinion polls this year, the prime minister has been talking tough on immigration – but the figures around Channel crossings have made for difficult reading.

Cubs blow lead in 10-run 8th, storm back in thriller

Cubs blow lead in 10-run 8th, storm back in thriller

CHICAGO — Kyle Tucker had the fans on their feet, roaring and pumping their fists as he rounded the bases after hitting the go-ahead two-run homer in the eighth inning. His screaming line drive cleared the right-field wall with plenty of room to spare.

The Chicago Cubs went from giving up 10 runs in the eighth to scoring six in the bottom half and beating the Arizona Diamondbacks 13-11 on Friday in one of the wildest games on record.

The two teams combined for 21 runs in the seventh and eighth innings, with the Cubs scoring 11 runs and the D-backs plating 10. It was the first nine-inning game in MLB history in which both teams scored 10 or more runs from the seventh inning on, and the third game overall, according to ESPN Research.

“That’s kind of baseball,” Tucker said. “There’s a lot of ups and downs in this game, especially with how many games we play.”

There haven’t been many games like this, though.

The Cubs are just the seventh team in at least the past 125 seasons to allow 10 or more runs in an inning and win. They are also the fifth team to give up 10 or more runs and score six or more in the same inning.

The 16 combined runs in the eighth were the most in an inning at Wrigley Field, according to the Elias Sports Bureau.

“If you’ve seen that one, you’ve been around for a while,” Cubs manager Craig Counsell said with a laugh. “It was crazy. You know, we gave up 10 runs in an inning and we won. So it was a wild game, but we kept going, and, you know, there’s 27 outs in a game and this kind of proves it, and you’re just happy to get out with a win.”

On a warm day with the ball carrying, Carson Kelly homered twice. Ian Happ belted a grand slam and Seiya Suzuki went deep, helping the Cubs open a weekend series on a winning note.

“You’ve seen it early — having some tough losses, coming back winning the next day,” Happ said. “Losing the first game of the series, winning the series. Little things like that. Today’s a great example of professional hitters going out there and continuing to have really good at-bats.”

The way things transpired in the final two innings was something to see.

Kelly hit a two-run homer in the second against Corbin Burnes, and Happ came through with his grand slam against Ryne Nelson as part of a five-run seventh. But just when it looked as if the Cubs were in control with a 7-1 lead, things took a wild turn in the eighth.

Eugenio Suarez cut it to 7-5 with a grand slam against Porter Hodge, Geraldo Perdomo singled in a run and Randal Grichuk put Arizona on top by one with a two-run double. Lourdes Gurriel Jr. hit a three-run homer, making it 11-7.

The crowd of more than 39,000 let the Cubs hear it, but their team regrouped in the bottom half. Bryce Jarvis hit Nico Hoerner leading off and walked Pete Crow-Armstrong before Kelly drove a three-run homer to center. Tucker, the Cubs’ prized offseason addition, came through after Happ singled with one out. Suzuki followed with his drive against Joe Mantiply to give the Cubs a 13-11 lead.

Arizona, which had won five straight, became just the third team over the past 50 seasons to lose a game in which it had a 10-run inning at any point, according to ESPN Research.

“You just got to stay locked in,” Kelly said. “Obviously, you don’t want to … give up 10 in an inning. Obviously, you don’t want to do that. I think the biggest thing is coming back, regrouping and continuing to fight.”

Chisholm suspended 1 game for conduct, tweet

Major League Baseball suspended New York Yankees infielder Jazz Chisholm Jr. for one game and fined him an undisclosed amount, the result of his actions during Thursday night’s win against the Tampa Bay Rays.

Chisholm was ejected in the seventh inning by plate umpire John Bacon for arguing after a called third strike on a full-count pitch from Mason Montgomery that appeared low.

Minutes later, he posted on his X account, “Not even f—ing close!!!!!” then deleted the post.

“I didn’t think before I had anything that I said was ejectable but after probably,” Chisholm said after the game. “I’m a competitor, so when I go out there and I feel like I’m right and you’re saying something to me that I think doesn’t make sense, I’m going to get fired up and be upset.

“I lost my emotions. I lost my cool. I got to be better than that. … I’m definitely mad at myself for losing my cool.”

Michael Hill, the league’s senior vice president for on-field operations, said Friday’s discipline was for Chisholm’s “conduct, including his violation of Major League Baseball’s Social Media Policy for Major League Players.”

MLB regulations ban the use of electronic devices during games. The social media policy prohibits “displaying or transmitting content that questions the impartiality of or otherwise denigrates a major league umpire.”

Chisholm did appeal the decision, allowing him to play in Friday night’s 1-0 win against the Rays. He started at second base and went 0 for 4 with two strikeouts.
