The habitability of a planet depends on a myriad of stellar and planetary parameters, many of which we are just beginning to understand. Additionally, only a small fraction of these parameters are likely to be directly observable by the first, or even subsequent generations of astronomical telescopes. Our initial assays, will try to estimate the probability that a planet is habitable based on basic information such as mass and/or size of the planet, its orbital characteristics and information about its composition. To more definitively determine habitability, we must either directly detect large bodies of surface water, or attempt to constrain the surface temperature and pressure via a combination of observations and modeling. This presentation will summarize detection techniques and likely remote-sensing signs of habitability using techniques such as transmission spectroscopy and disk-integrated time-resolved photometry and spectra. We will also discuss the development of a "habitability factor", a means of combining stellar and planetary processes and relating them to observables to constrain the likely habitability of a discovered planet. This work is supported by the NASA Astrobiology Institute.
