Penguin Galaxy - Arp 142 vulcano and layers of gas shedThis striking NASA Hubble Space Telescope image, which shows what looks like the profile of a celestial bird, belies the fact that close encounters between galaxies are a messy business. This interacting galaxy duet is collectively called Arp 142. The pair contains the disturbed, star forming spiral galaxy NGC 2936, along with its elliptical companion, NGC 2937 at lower left. Once part of a flat, spiral disk, the orbits of the galaxy's stars have
