WASHINGTON—The 2019 release of the first image of a black hole was hailed as a significant scientific achievement. But truth be told, it was a bit blurry—or, as one astrophysicist involved in the effort called it, a “fuzzy orange donut.”
Scientists on Thursday unveiled a new and improved image of this black hole—a behemoth at the center of a nearby galaxy—mining the same data used for the earlier one but improving its resolution by employing image reconstruction algorithms to fill in gaps in the original telescope observations.
