    Hello,
    Could somebody tell me what this actually is?
    I really don't have a clue

    The long green stripe is a satellite trail 😃

    From http://talk.galaxyzoo.org/#/boards/BGZ0000003/discussions/DGZ1006byh :

    Satellites sometimes pass overhead as the telescope is observing and reflect light in a streak across the image as they pass by. They
    move quickly so their trails are always a single color: red, green, or blue. Sometimes you can classify the central galaxy, other times
    there is no central galaxy because the computer got a bit confused.
