    • Alien Maps of an Ocean-Bearing World 

      Cowan, Nicolas B.; Agol, Eric; Meadows, Victoria S.; Robinson, Tyler; Livengood, Timothy A.; Deming, Drake; Lisse, Carey M.; A'Hearn, Michael F.; Wellnitz, Dennis D.; Seager, Sara; Charbonneau, David (Institute of Physics, 2009)
      When Earth-mass extrasolar planets first become detectable, one challenge will be to determine which of these worlds harbor liquid water, a widely used criterion for habitability. Some of the first observations of these ...

    • The Effect of Orbital Configuration on the Possible Climates and Habitability of Kepler-62f 

      Shields, Aomawa L.; Barnes, Rory; Agol, Eric; Charnay, Benjamin; Bitz, Cecilia; Meadows, Victoria S. (Mary Ann Liebert, Inc., 2016)
      Abstract As lower-mass stars often host multiple rocky planets, gravitational interactions among planets can have significant effects on climate and habitability over long timescales. Here we explore a specific case, ...

    • The NASA Astrobiology Roadmap 

      Meadows, Victoria S.; Hedges, S. Blair; Turner, William W.; Farmer, Jack D.; Falkowski, Paul G.; Boss, Alan P.; Deamer, David; Nealson, Kenneth H.; Woolf, Neville J.; Pilcher, Carl B.; Benner, Steven A.; Spormann, Alfred M.; Trent, Jonathan D.; Meyer, Michael A.; Jakosky, Bruce M.; Knoll, Andrew; Liskowsky, David R.; Yorke, Harold W.; Allamandola, Louis J.; Des Marais, David J. (Mary Ann Liebert, Inc., 2003)
      The NASA Astrobiology Roadmap provides guidance for research and technology development across the NASA enterprises that encompass the space, Earth, and biological sciences. The ongoing development of astrobiology roadmaps ...

    • Rotational Variability of Earth's Polar Regions: Implications for Detecting Snowball Planets 

      Cowan, Nicolas B.; Robinson, Tyler; Livengood, Timothy A.; Deming, Drake; Agol, Eric; A'Hearn, Michael F.; Charbonneau, David; Lisse, Carey M.; Meadows, Victoria S.; Seager, Sara; Shields, Aomawa L.; Wellnitz, Dennis D. (American Astronomical Society, 2011)
      We have obtained the first time-resolved, disk-integrated observations of Earth's poles with the Deep Impact spacecraft as part of the EPOXI mission of opportunity. These data mimic what we will see when we point next-generation ...
