Björn Jónsson produces beautiful color and 3D global mosaics of Vesta from Dawn's archival data.

Voyager 1 revisited: Io and Europa transiting Jupiter

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

Pretty picture: Landsat view of southern Greenland

This is a very large (19000 pixels square) mosaic of the fjords and glaciers of southern Greenland. I had been interested for a long time in experimenting with the processing of Earth satellite imagery just to get a comparison to the other planets.

Vesta is one of the more colorful asteroids in the solar system. This view is composed of 17 individual color frames, carefully assembled and draped over a digital model of the shape of Vesta. The color has been corrected to match Vesta's visible spectrum.

The 12 images comprising this Galileo Solid-State Imaging Experiment (SSI) mosaic were obtained on November 25, 1999 at a distance of 96,000 km from Europa. This is the only good global coverage of Europa's Jupiter facing hemisphere. For aesthetic purposes, some narrow horizontal gaps were filled by cloning nearby data.

Nine images from Venus Express display some of the variety of features visible in Venus' clouds in the VMC data set: global views, atmospheric waves, features that appear dark in the UV, a bright south polar band, thermal emission from the surface, and so on.
