Astronomers have identified one of the mysterious distant red dots observed by JWST GLIMPSE-17775 as a black hole star (BH*) aka a quasi star.

Unlike a regular star that is powered by fusion at its core, a BH* is powered by a black hole and material falling into it. A dense cocoon of partially ionized gas surrounds the BH, which modifies emitted radiation, e.g. it absorbs UV and X-rays.

GLIMPSE-17775 existed 1.8 bil years after the big bang.
