A joint effort between astrophysicists at the Institute for Advanced Study, Georgia Tech, and the NSF NOIRLab have produced a sharper image of M87, the supermassive black hole first visualized in 2019. A new machine-learning technique, named PRIMO, enhances the sharpness and fidelity of the radio interferometric image. The new algorithm offers a makeover to the “fuzzy, orange donut.”
