New study traces Io’s volcanic tides

Hundreds of volcanoes pockmark the surface of Io, the third largest of Jupiter’s 78 known moons, and the only body in our solar system other than Earth where widespread volcanism can be observed. A new study finds Io’s most powerful, persistent volcano, Loki Patera, brightens on a similar timescale to slight perturbations in Io’s orbit caused by Jupiter’s other moons, which repeat on an approximately 500-Earth-day cycle.

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.

What can geysers tell us about volcanoes on Earth and on distant moons?

Susan Kieffer’s research focuses on geological fluid dynamics with an emphasis on geysers, rivers, meteorite impacts, and volcanoes. An interview provided a good opportunity to catch up with her on planetary science, her career, and current research.
