Xavier Dumusque is the young astronomer who was lead author for the announcement of the first exoplanet found in the Alpha Centauri system, just 4.3 light years from Earth.  It's also the first Earth-sized world found outside our own system. Emily Lakdawalla wowed the crowd at the Galaxy party in LA, and you'll hear what other listeners think Curiosity SHOULD have found on Mars in our What's Up contest.

"NASA announced today the astonishing discovery by the Curiosity rover of a huge meteorite on the surface of Mars. Mineralogical testing revealed that the meteorite is actually composed of bedrock from the North American continent and has been on Mars for roughly 65 million years.  Incredibly, all evidence indicates that this object was ejected from Earth by the cataclysmic impact that brought the age of dinosaurs to a close. Although the geologic and chemical signatures are compelling, the undeniable evidence for NASA's conclusion was the active colony of American Cockroaches living in and around the big rock. In making the announcement, NASA's administrator said,'This discovery will go down in the history books. Today we have proven that an asteroid impact really did kill off the dinosaurs, that Panspermia is a viable concept, and that cockroaches really will be the last living species from the Planet Earth.' He went on to say that NASA is working on a new $1.5 billion mission to safely land on Mars a roach motel the size of a Volkswagen Beetle." from Curt Lewis

"Mars Nazis" from Karol Nowak
