In simulations, supermassive stars form and collapse into large black-hole seeds that can rapidly grow in gas-rich environments, making the Little Red Dots a plausible visible stage of early black-hole formation.

These black-hole seeds are surrounded by dense gas disks that trap radiation, enabling growth rates far faster than in the modern universe.

The resulting black holes emit spectra that closely match the observed spectra of Little Red Dots, explaining why these objects exhibit traits of both quasars and primordial stars.

NASA, ESA, CSA, and researchers including Kevin Luhman, Catarina Alves de Oliveira, and Mahdi Zamani contributed to the project, with Webb being an international program led by NASA in collaboration with ESA and CSA.

Webb is an international collaboration among NASA, ESA, and the Canadian Space Agency, with ESA supplying key instruments (NIRSpec and part of MIRI) and launch services via Ariane 5.

The Webb mission, a joint international program led by NASA with ESA and CSA, is dedicated to exploring the solar system, distant worlds, and fundamental cosmic questions.

Webb’s infrared vision complements Hubble’s optical data, helping reveal structures and stellar populations that are hard to see in a single wavelength.

Future work includes using spectroscopy to separate host-galaxy light from central engines, identifying local analogs for study, and combining multi-wavelength observations from multiple telescopes.

JWST captured a large, detailed panorama of the star-forming region IC 348, about 1,000 light-years away in Perseus, highlighting young stars and brown dwarfs.

Spectral analysis found a hydrocarbon feature in the atmospheres of the lowest-mass brown dwarfs, suggesting a possible new spectral class for these objects.

Astronomers in IC 348 using JWST identified a potential new spectral class of brown dwarfs, labeled class H, defined by the 3.4 μm hydrocarbon absorption feature.
