AI Algorithm Enhances Image of M87's Black Hole to Unprecedented Clarity

Astronomers have used machine learning to improve the Event Horizon Telescope’s first black hole image, aiding in black hole behavior understanding and testing gravitational theories. The new technique, called PRIMO, has potential applications in various fields, including exoplanets and medicine. The researchers say the new image should lead to more precise determinations of the mass of M87’s black hole and the extent of its event horizon and accretion ring.
