This is that little red dot, GLIMPSE-17775. Its red shift means we're seeing it as it appeared 1.8 billion years after the Big Bang. Spectral data from JWST tell us it's a rapidly growing black hole surrounded by a cloud of superheated gas. This kind of star was only first hypothesised in 2006.

Thanks. This sure helps keep things here on Earth on perspective.

what do you mean? is it one of those putative black hole stars that could only exist in the very very early universe? (i would have thought 1.8Gyr was too much)
