The first image of a black hole captured four years ago revealed a fuzzy, fiery doughnut-shaped object. Now, researchers have used artificial intelligence to give that cosmic beauty shot a touch-up.
The updated picture, published Thursday in the Astrophysical Journal Letters, keeps the original shape, but with a skinnier ring and a sharper resolution.
The image released in 2019 gave a peek at the enormous black hole at the center of the M87 galaxy, 53 million light-years from Earth. A light-year is 5.8 trillion miles. It was made using data gathered by a network of radio telescopes around the world, showing swirling light and gas.
But even with many telescopes working together, gaps remained in the data. In the latest study, scientists relied on the same data and used machine learning to fill in the missing pieces.
The resulting picture looks similar to the original, but with a thinner “doughnut” and a darker center, researchers said.
“For me, it feels like we’re really seeing it for the first time,” said lead author Lia Medeiros, an astrophysicist at the Institute for Advanced Study in New Jersey.
By having a clearer picture, researchers hope to learn more about the black hole’s properties and gravity in future studies. And Medeiros said the team plans to use machine learning on other images of celestial objects, including possibly the black hole at the center of our Milky Way galaxy.

Lawmakers are still struggling to figure out how to regulate big tech companies as they grow bigger and get even more powerful. Evan Greer, director of the digital rights organization Fight for the Future, joined Cheddar to discuss key takeaways from the year, as well as what we can expect for big tech and regulation in 2022.
Bumble users are remaining active on the dating app and still linking up with potential matches despite the emergence of the omicron variant of COVID-19. CEO Whitney Wolfe Herd noted that no matter what is happening in the world, people will always need to connect.
There seems to be no stopping the crypto craze, and this week has been no exception. Dogecoin surged after ‘Time Person of the Year' Elon Musk tweeted that Tesla will accept some payments in the digital token. Everett Millman, Crypto & Metals Analyst at Gainsville Coins, gives Cheddar insight into just how much influence Musk has over the crypto world.
As the world of crypto evolves, the need from investors for some type of stability within crypto is also growing. Enter stablecoins. Stablecoins serve as a crypto-equivalent which hold their value, and allow investors to quickly move their profits across currencies. Patrick McConlogue, CEO of Overline and former Citadel Investment Group engineer, explains what to expect ahead of the U.S. Senate Banking Committee’s stablecoin hearing, as regulatory tensions between the crypto market and the government continue to hover in limbo.
