Jonathan I. Lunine is an American planetary scientist and physicist
. Lunine teaches at Cornell University
, where he is the David C. Duncan Professor in the Physical Sciences. Having published more than 200 research papers, Lunine is at the forefront of research into planet formation, evolution, and habitability
. 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.
He is the David Baltimore Distinguished Visiting Scientist at NASA
’s Jet Propulsion Laboratory
(2008–2010). He is an interdisciplinary scientist on the Cassini mission to Saturn
, and on the James Webb Space Telescope
, as well as co-investigator on the Juno mission under development for launch to Jupiter
. He is a member of the U.S. National Academy of Sciences
, a fellow of the American Association for the Advancement of Science
and of the American Geophysical Union
. He earned a B.S. in Physics and Astronomy from the University of Rochester
in 1980, followed by M.S. (1983) and Ph.D. (1985) degrees in Planetary Science from the California Institute of Technology
.
, largest moon of Saturn
. He thinks that, Titan should be studied not for the reason that it may sustain life but because it can provide us with some valuable information about the condition of Earth
before the formation of life.
Physicist
A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

Planetary habitability
Planetary habitability is the measure of a planet's or a natural satellite's potential to sustain life. Life may develop directly on a planet or satellite or be transferred to it from another body, a theoretical process known as panspermia...
. His work includes analysis of brown dwarfs
Brown dwarf
Brown dwarfs are sub-stellar objects which are too low in mass to sustain hydrogen-1 fusion reactions in their cores, which is characteristic of stars on the main sequence. Brown dwarfs have fully convective surfaces and interiors, with no chemical differentiation by depth...
