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.
