Taking advantage of a rare orbital alignment between two of Jupiter’s moons, Io and Europa, researchers have obtained an exceptionally detailed map of the largest lava lake on Io, the most volcanicall...
Crater clusters on Mars:Shedding light on martian ejecta launch conditions
Cratering Mars Meteorites Impact processes
2015/12/25
We have identified two classes of crater clusters on Mars. One class is “small clusters” (crater diameter D ～ tens m, spread over few hundred m), fitting our earlier calculations for the breakup of we...
The dark side of the Albano crater lake
Alban Hills volcano Albano Lake multibeam bathymetry

The present study illustrates the procedures applied for the coordinate system conversion of the historical fumarole positions at La Fossa crater, to allow their comparison with newly acquired global ...
The ring-shaped thermal field of Stefanos crater, Nisyros Island: a conceptual model
The ring-shaped thermal field Stefanos crater, Nisyros Island conceptual model
2015/1/6
Fumarole fields related to hydrothermal processes release the heat of the underground through permeable pathways. Thermal changes, therefore, are likely to depend also on the size and permeability var...
Mineralogical characterization of Martian Jezero crater from MRO CRISM hyperspectral images
Planetary mapping Hyper spectral Minerals Mars
2014/7/23
Martian mineral detection and mapping can provide important information and constraints on Martian aqueous history, which can be used to assess the potential habitability of Mars. The key parameters t...
