An article published in “The Astrophysical Journal” reports a study on AzTECC71, what appears to be a dusty primordial galaxy in which remarkable star formation is taking place. A team of researchers from the COSMOS-Web collaboration led by Jed McKinney of the University of Texas at Austin observed what appeared to be a ghost galaxy with the James Webb Space Telescope. The peculiarity of this study is that AzTECC71 was detected by some ground-based telescopes but didn’t appear to the Hubble Space Telescope. This may be a much more common case than previously thought that requires some sort of ghostbuster to find.
