ESA/VIRTIS/INAF-IASF/Obs. de Paris-LESIA
This movie, built with infrared images taken by the Ultraviolet/Visible/Near-Infrared spectrometer (VIRTIS) on board ESA’s Venus Express, provides a close-up view of the double-eyed vortex at Venus south pole. The images (ranging from 4.5 to 5.1 microns) were taken on 29 May 2006, from a distance of about 64 000 kilometres from the planet.
Thanks to the use of different wavelengths, VIRTIS probed the atmosphere at different depths, ranging from 70 kilometres to about 60 kilometres altitude. It is interesting to see how the images contrast and the details increase while approaching the 60 kilometres altitude.
