Scientists Are Creeping Closer to Colorized Black Hole Images

The Event Horizon Telescope (EHT) has made history by successfully capturing full-color images of black holes for the first time. By using a groundbreaking technique called frequency phase transfer, they correct atmospheric interference to stitch together multi-frequency data, allowing them to observe these cosmic phenomena in vivid color. This advancement builds on their 2019 and 2022 achievements imaging M87* and Sagittarius A*, respectively, and sets the stage for a new space-based mission, Event Horizon Explorer, aiming to achieve even sharper visuals of black holes, including elusive photon rings that could validate theories about black hole physics.
