Extrasolar Planets—LASP Center for Astrobiology
January 26—28, 2007—Boulder, Colorado
The 2007 workshop focused on the field of astrobiology and understanding the potential and actual distribution of life in our solar system and in the universe. (Courtesy NASA/JPL)
Themes:
- How common are terrestrial (habitable) planets in the universe?
Almost all known extrasolar planets are large, Jovian planets. Many are “hot Jupiters” (or medium-hot Jupiters) because they are the easiest to find with the Doppler method. Under what circumstances might we expect terrestrial planets to occur? - What do the 200+ known extrasolar planet discoveries tell us about planet formation?
Fifteen years ago, no one would have expected hot Jupiters in sub-AU orbits. What new ideas of solar system formation and development does that discovery point to? - The history of the discovery of extrasolar planets and the evolution of technology that enabled discoveries.
There are several different techniques for finding extrasolar planets (see Searching for Other Worlds—The Methods) - Habitability: Life in the Universe.
The discovery of potential habitable zones in the outer solar system (Titan, Enceladus, etc.) has changed our view of where life can exist. - How does a NASA mission develop from big science ideas to a science platform to an engineering program to launch?
We use the Kepler mission as an example. It only takes about 2 decades…
