Edwin Hubble famously kept the company of his black cat Copernicus on late nights at the Mount Wilson Observatory. At STScI, these are just a fraction of the pets who keep us company while we expand the frontiers of space astronomy.

The BH* scenario not only fits GLIMPSE-17775; it also accounts for why most little red dots are faint in X-rays, since any such emission is likely absorbed by the dense gas cocoon. (5/5) 🔭 🧪 🧵 #NASAWebb

By carefully analyzing the GLIMPSE-17775’s spectrum captured by Webb—the deepest spectrum to date of a little red dot—a research team has identified multiple lines of evidence, all of which support the interpretation that the little red dot is a supermassive black hole. (2/5)

The complex puzzle known as little red dots has become more complete since their initial discovery by the James Webb Space Telescope in 2022. Now a particular little red dot’s spectrum is helping connect many of the pieces. #NASAWebb (1/5) 🧵 🔭
This little red dot is more distant than the galaxy cluster and magnified by gravitational lensing. (GLIMPSE-17775 has a cosmological redshift of 3.5, meaning it existed about 1.8 billion years after the big bang.) (4/5)
