Unmasking Europa
We may not be able to judge a book by its cover, but hopefully we can judge a moon by its surface. Jupiter’s moon Europa is a primary target of astrobiology in our solar system because some scientists think it may harbor a habitable ocean beneath it’s icy crust. Richard Greenberg, professor in the Lunar and Planetary Laboratory at the University of Arizona and former member of the imaging team of NASA’s Galileo spacecraft, has now released a book about the scratched and splotchy surface of Europa.Source: [Astrobiology Magazine]

Wandering Poles on Europa
A new study in the May 15th issue of Nature from NAI’s Carnegie Institution of Washington Team reveals that Europa’s poles may not have always been located in the same place. Using images from three NASA spacecraft, Voyager, Galileo, and New Horizons, the study mapped surface features on Europa and matched them with a pattern predicted if Europa had experienced an episode of ~80 degree true polar wander. This movement of the pole and subsequent change in rotation axis is only possible if Europa’s outer shell is decoupled...
