PGS: Kepler & Exo-Earths

The October meeting of the Potomac Geophysical Society will be held October 21st at the Fort Myer Officers’ Club in Arlington, VA in the Campaign Room.

This month’s talk will be: The NASA Kepler Mission and the Search for Exo-Earths by Prof. Harold Geller, George Mason University.

We will discuss the various methods utilized in the search for planets orbiting other stars. We will specifically examine the search technique utilized by NASA’s Kepler mission, as well as some of the latest data released. We will also examine some of the media reports about these results and the continuing effort to find planets orbiting stars other than our Sun, that are most like Earth.
