Overview
- A team led by Rohan Naidu used James Webb Space Telescope data to identify MoM-BH*-1, a red, solar-system–scale object whose light comes from about 660 million years after the Big Bang.
- Spectra show an unprecedentedly deep Balmer break and virtually no metal lines, and the researchers argue those features come from a very dense screen of hydrogen rather than dust.
- The study, published in Nature on Wednesday, August 12, 2026, finds that simulations with an actively accreting central black hole best reproduce the object’s extreme luminosity and spectrum.
- Modeling yields a preferred scenario with a central black hole of order 10^5 solar masses surrounded by a star-like hydrogen envelope, which would produce energy levels far above what nuclear fusion can supply.
- The authors propose that similar gas-enshrouded systems could account for many of JWST’s 'little red dots,' but they say further targeted JWST and multiwavelength follow-up is needed to confirm the interpretation and find more examples.
