Astronomy Cast Ep. 769: Little Red Dots

By Fraser Cain & Dr. Pamela Gay

Streamed live on Oct 20, 2025.

New instruments bring new mysteries, and when James Webb came on line it uncovered a collection of strange, compact, bright objects shifted deeply into the red end of the spectrum. These were dubbed "Little red dots" or LRDs. And the astronomical community continues to puzzle over what they are. When JWST first peered into the distant past, it discovered the early universe had a rash of little red dots. Their existence just 450 million years after the big bang meant either galaxies were forming way faster than anyone predicted, or something unimagined had been found.
