Do Prehistoric Aliens Paint Their Caves?

There is no scientific evidence for the existence of aliens, but astronomers are increasingly finding the universe to be a habitable place.  If extraterrestrial beings do exist, how would their artwork necessarily differ from our own?  Dan Ruby will speculate on possible answers through his own experience in art making and astronomy.  Fleischmann Planetarium Director at the University of Nevada, Reno, Dan Ruby is actively involved in ongoing planetary research around extraterrestrial caves and minor planets. He is a trained as a NASA educator in heliophysics and airborne infrared astronomy, and (probably unsurprisingly) a huge sci-fi nut.
