wow these ufo's look like the underside of the telescope that took the pictures (mt. palomar)!!!! coincidence? no. ufo's have been reverse engineering spaceships to look like double-exposures of our telescope mirrors for years!!!
i've seen many of these objects on google sky as well, and oddly enough i have seen them next to streak like objects (and inside these streaks) i thought for a minute it could be ufo's in a wormhole… because these figures tend to only exit at either end of the streak/tube. i don't know!
