Yes, we humans excel at seeing patterns and shapes everywhere around us, including out in space.

Also, as explained in the video, 20 years ago today — on February 14, 1990 — the Voyager 1 spacecraft took the famous "Pale Blue Dot" image, where it turned around and took a picture of Earth. From 6 billion kilometers (4 billion miles) away Earth appeared as a "mote of dust suspended in a sunbeam" as Carl Sagan phrased it. It truly is one of the most "romantic" images ever as it can't help but evoke strong emotions by anyone who sees it. "That's here, that's home, that's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives," said Sagan.
