@mark_bril@RileyRalmuto Hubble and Webb data are stored and distributed to the scientific community through MAST, which is operated by the Space Telescope Science Institute (Also the science operations center for Hubble and Webb). They also built this application. https://t.co/NCRBkJWkAA
@RileyRalmuto Just to avoid any confusion, the background images you see are coming from the Two Micron All Sky Survey (Near IR) for the Webb observation data and the Digitized Sky Survey 2 (Visible) for the Hubble observation data. This info can be found in the User Guide.
