The James Webb Telescope discovered that the mysterious red dots are not hot disks around black holes, but dense clouds of water vapor with temperatures around 2000–4000 °C. This reduced the mass estimates of black holes by an order of magnitude.

The James Webb Space Telescope has spotted mysterious "Little Red Dots" in the early universe—compact objects that don't fit standard models. A new study suggests they may be quasi-stars: black holes shrouded in a dense gas cocoon that thermalizes radiation like a giant furnace. Calculations using t
