On occasion I saw these seven story tall, two mile diameter ships with a yellowish glow against the black background of space. I can not recall if there was a significance to each ship having it's own (lights) color scheme. Near these large craft, smaller circular and triangular shuttle craft were seen. The light blue shaded areas are bright bands of millions of stars from our Milky Way Galaxy, which looked as delicate as clouds. The dark blue stars are brilliant and reminded me of diamonds refracting sunlight.
