The images depicted here are being described as 'alien bases' found on Google Space. We don't know what they are, but the likelihood is that there is an ordinary explanation. Nevertheless, they are unusual enough to deserve a look.
These are almost certainly artifacts internal to the particular telescope that collected the images for this composite. Aside from looking like lens flares to begin with, if there were objects that easy to see we'd hear no end of it from amateur astronomers from around the planet.
