  4. Water Vapor Detected on Extrasolar Planet


    An international team of researchers including members of NAI’s Virtual Planetary Laboratory Team have, using NASA’s Spitzer Space Telescope, detected the presence of water vapor on the hot jupiter HD 189733b. Published in this week’s Nature, the study’s primary author, Giovanna Tinetti, was a 2003 NAI Postdoctoral Fellow.

  5. Final Assembly of Earth-Like Planets


    NAI Postdoctoral Fellow Sean Raymond leads a team of authors from NAI’s University of Colorado, Boulder, and University of Arizona Teams, and Virtual Planetary Laboratory and University of Washington Alumni Teams in a new publication in Astrobiology. They present analysis of water delivery and planetary habitability in 5 high-resolution simulations forming 15 terrestrial planets. Their results outline a new model for water delivery to terrestrial planets in dynamically calm systems, which may be very common in the Galaxy.

  6. Direct Observation of Magnetic Field on Tau Bootis


    An international team of researchers including NAI Postdoctoral Fellow Evgenya Shkolnik of the University of Hawai’i Team publish their observation in this month’s Royal Astronomical Society Letters of a magnetic field at the surface of star Tau Bootis, which is orbited by a giant planet every three days. The magnetic field’s intensity is similar to that of the Sun, but the star and the planet are tidally locked, possibly producing the observed magnetic knots.

  7. NASA Study Shows Titan and Early Earth Atmospheres are Similar


    Organic haze in the atmosphere of Saturn’s moon, Titan, is similar to haze in early Earth’s air — haze that may have helped nourish life on our planet— according to a NASA Astrobiology Institute study released Nov. 6, 2006.
