    While identifying galaxy's I came across this odd picture. Any idea what it is or causes it?

    Welcome to Galaxy Zoo, flipit4u!

    It's a #satellitetrail, a kind of #artifact. It's the reflection of sunlight off a satellite that was passing through the field viewed by the camera (through the r-band filter, here presented as green). They're actually quite common, and you may come across red and blue ones too.

    Happy hunting! 😃
