New evidence of watery plumes on Jupiter’s moon Europa

Scientists are keen to explore beneath Europa’s thick blanket of ice, and they can do so indirectly by hunting for evidence of activity emanating from below. A new study published in the AGU journal Geophysical Research Letters, did exactly this.

Odd behavior of Jovian moon dust could inform future space missions, search for life

New research into the movements of dust around Jupiter’s four largest moons could help scientists searching for life in our solar system, according to a new study. This moon dust around Jupiter could give scientists clues about the composition of the surface of its satellites.

New research shows impacts from comets or asteroids could have created Europa’s chaos terrain

What began as Williams College students requesting a new course on planets and moons nearly 12 years ago has now culminated in a new research paper showing that impactors, such as comets or asteroids, can penetrate the frozen surface of Jupiter’s moon Europa. Since 2004, undergraduate students led by Rónadh Cox, professor of geoscience, have studied the ice-covered surface of Europa, trying to understand the origins of its chaos terrain: areas that look like crustal breaches, with icebergs embedded in frozen slush.

AGU 2012: Days 1 and 2 Highlights

Greetings! It’s been a busy first two days of AGU, and it’s impossible to convey it all, but here are a few highlights: Monday morning was my poster presentation, so that prevented me from seeing very many talks. I did stop by the Mars talks long enough to hear ChemCam team member Darby Dyar give a talk summarizing the many challenges involved in getting quantitative numbers out of LIBS data, …

AGU 2010 – Day 2: Shoemaker Lecture and Icy Moons

My massive summary of the Day 2 AGU planetary sciences talks, starting with the Shoemaker Lecture, and then covering Titan, Enceladus and other icy moons. Hydrocarbon volcanoes and icy geysers and hidden oceans, oh my!
