Overview
- An international MIT‑led team identified MoM-BH*-1 in JWST data as a compact, very luminous red source at redshift ≈7.76 seen about 660 million years after the Big Bang.
- The object's spectrum shows an exceptionally deep Balmer break, complex hydrogen emission and absorption, and almost no metal lines, a combination that rules out ordinary stellar populations.
- Simulations that place a roughly 10^5–10^7 solar‑mass black hole inside a solar‑system–scale, dense hydrogen envelope best reproduce the observed colors, line shapes and extreme luminosity.
- The authors stress the interpretation is provisional and call for targeted follow‑up — repeat JWST imaging, high‑resolution NIRSpec spectra and X‑ray and radio searches — to test for hidden accretion and variability.
- If confirmed, the black‑hole‑star picture would help explain how massive black holes grew quickly in the early universe and could account for a large fraction of the ≈241 Little Red Dot candidates found in recent JWST surveys.
