Summary

Astronomers using NASA's James Webb Space Telescope have identified a "little red dot" galaxy called GLIMPSE-17775, whose spectrum provides the strongest evidence yet for the existence of "black hole stars" — early universe objects that may be powered by supermassive black holes. The team led by Vasily Kokorev at UT Austin analyzed Webb's deepest spectrum of a little red dot, finding multiple lines of evidence supporting this interpretation. These little red dots, first discovered by Webb in 2022, are puzzling early-universe objects that could help bridge our understanding of how supermassive black holes and galaxies formed in the early cosmos.

The complex puzzle known as little red dots has become more complete since their initial discovery by NASA's James Webb Space Telescope in 2022.

By carefully analyzing the dot's spectrum captured by Webb — the deepest spectrum to date of a little red dot — the research team has identified multiple lines of evidence, all of which support the interpretation that GLIMPSE-17775

Now a particular little red dot's spectrum is helping connect many of the pieces.
