ERIC AGOL (Astronomer)

Eric Agol is an astrophysicist and professor at the University of Washington.  His objects of study:  black holes and planets, sometimes examined with telescopes, but more often with pen and paper.  Eric's equations are applied by astronomers worldwide to size up extrasolar planets.  His favorite planet: Kepler-62f, which he rescued from NASA data which had been cast aside by a buggy algorithm.

VIKKI MEADOWS (Astronomer)

Vikki Meadows is an astrobiologist and planetary astronomer whose research interests focus on acquisition and analysis of remote-sensing observations of planetary atmospheres and surfaces. In addition to studying planets within our own Solar System, she is interested in exoplanets, planetary habitability and biosignatures. Since 2000, she has been the Principal Investigator for the Virtual Planetary Laboratory Lead Team of the NASA Astrobiology Institute. Her NAI team uses models of planets, including planet-star interactions, to generate plausible planetary environments and spectra for extrasolar terrestrial planets and the early Earth. This research is being used to help define signs of habitability and life for future extrasolar terrestrial planet detection and characterization missions.
