    Does anyone know what can be causing this green glow?

    Hi @lolliegirl and welcome to Galaxy Zoo 😃

    The green glow is an artifact, in this case it could be caused by either slightly misaligned filters, mis-stacked images or even over saturation.

    Here is the slightly zoomed out image - see how other objects in the region also have the green streak in the same area?
