Astronomical Detection of Biosignatures From Extrasolar Planets (dm)

Motivated by the recent discoveries of a multitude of extrasolar planets, NASA has initiated a series of studies for space-based observatories that will be able to search for life on these worlds. To optimize the designs of these NASA missions, and to ultimately interpret the data that they return, we need to be able to recognize habitable worlds and to discriminate between planets with and without life.

The principal goal of this research is to learn how to recognize the presence of life on extrasolar planets by identifying the signatures of life in their spectra. To achieve this goal, we are developing a suite of innovative modeling tools to simulate the environments and spectra of extrasolar planets. The modeling tools will constitute a Virtual Planetary Laboratory, which will be used to explore the ... Continue reading.
