Astronomers refined the mass of three extremely distant galaxies using Webb, and it turned out: invisible dust can distort our estimates more than we imagined, but even with corrections, two galaxies remain monstrously massive for their young age.

The Webb telescope spotted red dots that look like galactic cores with enormous black holes. But a fresh analysis suggests they might be modest-sized objects wrapped in a dense gas cocoon. Just as fog makes a lantern seem like a huge red ball, the gas distorts our estimates. Inside, there may not be
