The JWST's NIRCam instrument captured this image of galaxy CANUCS-LRD-z8.6 only 570 million years after the Big Bang. CANUCS-LRD-z8.6 is one of the small, very distant and strikingly red galaxies called Little Red Dots (LRDs), which have been spotted in increasing numbers by Webb’s surveys of the early Universe. Astrophysicists are working hard to determine what exactly LRDs are. Image Credit: ESA/Webb, NASA & CSA, G. Rihtaršič (University of Ljubljana, FMF), R. Tripodi (University of Ljubljana, FMF).

Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies that have mystified astronomers, CANUCS-LRD-z8.6 represents a vital piece of this puzzle that challenges existing theories about the formation of galaxies and black holes in the early Universe. The discovery connects early black holes with the luminous quasars we observe today.
