Does Webb image of Jupiter show rock debris where giant ET Motherships are parked?

On July 12, NASA held an international live stream releasing the
first official images from the James Webb Space Telescope showing
distant exoplanets, galaxies, nebula, and a glimpse deep into our
universe. The next day, NASA stealthily released an image of
Jupiter taken by the Webb Telescope, which showed a noticeable
dark field just above the gas giant's atmosphere. Was it a
shadow, as NASA appeared to claim, or something entirely
different – part of a newly arrived extraterrestrial space fleet
secretly parked around Jupiter?
