Learn about the formation and origin of the Solar System and go beyond our neighborhood to investigate exoplanets (planets around other stars) in this video of class 11 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
Caution: Spacecraft Under Construction
Visiting JPL's high bay clean room with NASA Administrator Charles Bolden
Join Emily Lakdawalla and Mat Kaplan inside JPL's High Bay 1, where two Earth-revealing missions are being readied for launch.
Emily Lakdawalla and Courtney Dressing talked about just how common Earth-sized exoplanets may be in our neighborhood. Watch the replay here.
In the first full day of the annual meeting of the Division of Planetary Sciences of the American Astronomical Society, I listened to scientific sessions on icy worlds and on an exoplanet in a four-star system.

A large team of researchers has announced in a Nature article the discovery of not one, but two, Earth-sized planets orbiting a star named Kepler-20. This article separates the observational facts from the quite-likely-to-be-true inferences from the downstream speculations.

I wasn't able to watch the Kepler press briefing today so I will give you links to some of my favorite blogs for information on today's announcement, which follows a major data release last night as well as the publication of a paper in Nature.

The Kepler exoplanet hunting mission has made news today with a report of "its first rocky planet."

Two nearly simultaneous announcements by scientists that they have detected entire planetary system deep in space have set the astronomical community abuzz.

Congratulations to NASA's Kepler mission team on their announcement of the discovery of its first five exoplanets (planets around other stars). All five are "hot Jupiters," meaning that they are the sizes of the gas giants in our solar system, but are extremely close to their parent stars.
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
