The University of Arizona (also referred to as UA, U of A, or Arizona) is a Land-grant and space-grant public institution Having published more than 180 research papers, Lunine is at the forefront of research into planet formation, evolution, and habitability. Planetary habitability is the measure of a Planet 's or a Natural satellite 's potential to develop and sustain Life. His work includes analysis of brown dwarfs, gas giants, and planetary satellites. Within the Solar System, bodies with potential organic chemistry and prebiotic conditions—particularly Saturn's moon Titan—have been the focus of Lunine's research.
