  • These are generally everywhere in the new high resolution images.
  • They exhibit regular patterns of placement, though not on exact repeatable locations.
  • Some have tiny (possibly intentional) variations.
  • A possible explanation is "dirt in the lens." However, some have a complex cloud-like shape, or appear as very precise circular arcs.
  • Some could be inserted purposely for copyright protection or image alignment.
