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.

A year after the r/WallStreetBets community on Reddit drove GameStop and other meme stocks to unprecedented heights, the subreddit seems to be losing its luster among retail investors. Caitlin McCabe, markets and retail trading reporter from The Wall Street Journal, joined Cheddar to talk about the waning popularity of the group “Users are going on to find the next GameStop, and instead, they're seeing many of the new users who have joined the subreddit still talking about GameStop and AMC," McCabe noted. "And, they've become frustrated as they're ready to move on from those original meme stocks."
Tech titan Microsoft reported its second fiscal quarter of 2022 earnings on Tuesday, its first earnings report since announcing its plans to acquire gaming company Activision Blizzard in a multibillion dollar deal. Steve Larsen, co-founder of PlannerDAO, explains the role that cloud services played for Microsoft in the quarter and what the future may hold for Microsoft in the midst of the new acquisition.
Microsoft is expected to report financial results for its second fiscal quarter of 2022. It comes after the company beat on its top and bottom line in its previous four quarters. John Freeman of CFRA Research explains what investors will be keeping an eye out for as Microsoft continues to expand its domain.
