Webb Data Backs Black Hole Star Model for Redshift-3.5 Little Red Dot

Summary
The deepest spectrum yet of GLIMPSE-17775 shows multiple signatures consistent with a rapidly accreting supermassive black hole embedded in a dense, partially ionized gas cocoon.
Webb’s NIRCam and NIRSpec captured the object behind galaxy cluster Abell S1063, where gravitational lensing significantly boosted its brightness and enabled the unusually detailed measurement.
GLIMPSE-17775 dates to about 1.8 billion years after the Big Bang, giving astronomers one of the clearest tests so far of the BH* model proposed to explain the early universe’s “little red dots.”
The result strengthens a broader shift toward black-hole-based explanations for little red dots, though researchers say rival theories remain in play and a firmer answer may take another year or two.
Could these ancient 'little red dots' hold the key to solving the universe's dark matter mystery?
Are 'black hole stars' hiding a vast population of the Universe's earliest supermassive black holes?
Did supermassive black holes build the first galaxies, not the other way around?
Black Hole Stars Confirmed: JWST’s Breakthrough in Solving the Mystery of Early Universe Little Red Dots
Overview
The James Webb Space Telescope (JWST) has provided its strongest evidence yet for the existence of black hole stars (BH*) in the early universe by studying the mysterious Little Red Dots (LRDs). In June 2026, a landmark study focused on GLIMPSE-17775 used gravitational lensing to capture an exceptionally detailed spectrum, revealing features that match the predictions of the BH* model. This breakthrough not only confirms the nature of LRDs but also solves long-standing puzzles about their unexpected mass and abundance, marking a major step forward in understanding how supermassive black holes formed in the early cosmos.
