This image sequence shows thermal infrared radiation (at a wavelength of 3.8 microns) emitted by the cloud-tops at the southern polar region of Venus, as viewed by the VIRTIS imaging spectrometer on Venus Express. The scale has been inverted: white regions show cooler cloud, likely to be at higher altitude.
