Scientists may have discovered an explanation for a cosmic mystery uncovered by the James Webb Space Telescope several years ago: the origin of "little red dots" scattered across the cosmos.
In December 2022, six months after the launch of the super-powerful Webb Telescope, the telescope spotted something previously unseen: countless small red objects in the sky, which NASA says scientists soon dubbed “little red dots” (LRDs).
A puzzle to astronomers, scientists theorised the LRDs could be very dense galaxies or supermassive black holes. "For a time, the LRDs were framed as breaking cosmology because they defied practically every expectation set by well-founded theories," writes Lee Billings in Scientific American.
