Some DPS Meeting discoveries: Comparative Exo-planetology, Metalstar/metal planet, interacting planets, new KBO Planet possible, Spitzeropportunities, Enceladus water cycle, Jupiter lightning, Mercury's Sodium tail& CEV missions to NEO's
I just wanted to add that some of the discoveries made by Astronomers
and announced at that conference (abstracts of which can be found in the Bulletin of the American Astronomical Society) included: Astronomers announced that soon will there will be released the results of thermal measurements by Spitzer of the atmospheres of around 10 exoplanets and that the age of comparative planetology has arrived. An astronomer inferred from observations of transiting explanets that there is a correlation between high-metalicity stars and their being orbited by metal-rich planets. Astronomers presented evidence that 2 planets around HD155358 are "dynamically interacting with each other." Astronomers from Japan predict through simulations of the Kuiper belt shape that a planet several tenths of an Earth mass could be orbiting beyond Pluto. Attendees were made aware of a Spitzer Target of Opportunity Program which invites planet-hunters to participate. The New Horizons spacecraft observed polar lightning on Jupiter Astronomers predict from Enceladus plumes and tiger stripe shear that internal temperatures are hot and that it has a full liquid water cycle that could make it habitable. Astronomers reported a surprisingly long sodium tail for Mercury and and there was one paper "Piloted Missions to Near-Earth Objects via the Crew Exploration Vehicle". There was a lot more than the above presented at the conference. Abstracts from the Division of Planetary Sciences conference held in Orlando in Oct. '07 can be found via the Bulletin of the American Astronomical Society, Volume 39, No. 3.

One of the things I learned (out of the many) was that amateur astronomers were helpful in guiding the science that happened at the New Horizons Jupiter encounter. Below are some of the topics being discussed and published at the DPS conference this week (you can find more detailed abstracts of individual posters under each subject at the above website): Giant planets: Winds and Lightning Enceladus: Saturn's Fountain Sulfur and Sodium, Io and Mercury Giant Planets: Chemistry, Interior Structure, Aurorae, and Magnetosphere YORP Observed!
