    Hello, I just want to ask you, what do you think the two circles on the left side are? they look pretty interesting.

    UKIDSS (and other) images are full of (glare) artifacts - a product of bolometry.
    where available, the other comments are worth a look.
    have you seen the artifact/star discussions.
    also, please follow the "examine" link to NED and the Viewer.
