How much tidal stress does Jupiter put on Europa? Enough to break the ice. Panning et al. estimate the magnitude of the ambient seismic noise on Europa due to tidal cracking events and turbulence in its subsurface ocean.
Bonnie Buratti talks to Astrobites about Saturn, Pluto’s icy heart and the topic of her #AAS230 plenary talk – Rosetta and Comet 67/P.
Didn’t know comets had landslides too? Well, now you do!
With its dense atmosphere and liquid lakes, Titan is a moon like no other. In this bite we investigate the mechanism behind bright spots spotted on the lakes by Cassini.
Interstellar space should be littered with debris ejected during the formation of planetary systems—but how much? Engelhardt et al. use solar system surveys and simulations to place an upper limit on the number density of asteroids and comets roaming the Milky Way without a parent star.
Bright surface features ring Titan’s north polar lakes and trace out dry lake beds. Could these same features in the equatorial desert regions indicate that what is now desert was once covered in liquid?
