AI enhances first-ever black hole image into a 'skinny' doughnut.

Scientists have used machine learning to enhance the first-ever photo of a black hole, captured in 2019 by the Event Horizon Telescope Collaboration. The new image, released in The Astrophysical Journal Letters, shows a "skinny" doughnut with a darker and larger central region surrounded by a bright ring. The machine learning algorithm, called PRIMO, analyzed over 30,000 high-resolution simulated images of black holes to fill in the gaps of the original image. The new image can help scientists make more accurate measurements of the black hole's mass and understand its behavior.
