A remarkable ruby: Absorption in dense gas, rather than evolved stars, drives the extreme Balmer break of a little red dot at z = 3.5

Astronomers suggest that tiny red objects spotted by NASA's James Webb Space Telescope could be giant spheres of hot gas powered by supermassive black holes. The objects, called 'universe breakers,' defy prior understanding of galaxy formation and may represent an entirely new class of celestial object.
