It's the image of David Bowman from the film "2001: A Space Odyssey" which is a closeup of his face in a spacesuit helmet and he utters the words "My god, it's full of stars". Only David Bowman's head has in this image been replaced by the head of a young ginger kitty, whose eyes are open very wide and indeed they are full of stars. And the text reads "My god it's full of cats"
