  Welcome to Galaxy Zoo, Lady_Godiva22!

  It's a common artifact in UKIDSS images, likely a kind of 'ghost' (internal reflection of a bright star elsewhere in the field); however, no one seems to know why such ghosts are nearly always green (and not blue or red, or some combo).

  Happy hunting! 😃
