Figure 3 provides exemplar images of the equatorial region of Venus, which illustrate the variability of the UV contrasts, over a variety of scales as captured by the VMC on the Venus Express orbiter (Titov et al., 2012). Although Venus's cloud cover is nearly featureless in visible light, ultraviolet imaging reveals distinctive structure and pattern, including global-scale V-shaped bands that open toward the west (left). Caption: P-37218 : 9.2K : Hi-res: False color image of Venus' clouds as imaged by the NIMS instrument on Galileo. A UV image from Pioneer Venus is shown in Figure 49.1. Like volcanoes, impact craters are distributed nearly randomly on its surface.
The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990-1994 Magellan mission, is centered on the South Pole. Ultraviolet image of Venus' clouds as seen by the Pioneer Venus Orbiter (Feb. 26, 1979). The phenomenon also pointed to a mystery in the hothouse planet's atmosphere, they added. 30K : Hi-res: False color image of Venus' clouds as seen by the SSI instrument on Galileo. What’s weirder is that almost all of them (85 percent) appear pristine, apparently unmodified by the massive amounts of volcanic activity recorded in the surface features around them. One of the UV absorbers is SO 2, which has an absorption band in the wavelengths 210–320 nm. The wind circulation creates an upwards motion in Venus' atmosphere that carries water-rich air and ultraviolet-dark material up from below the cloud-tops, bringing it … Venus’ image is featureless in the visible light region; however, the observed ultraviolet (UV) images have a high contrast of bright and dark features, which reflects the distribution of UV absorbers. New research from ESA’s Venus Express probe is starting to reveal some of the secrets of Venus’s atmosphere, and some of them are very surprising indeed. Atmospheric measurements in the UV region have been performed by sounding rockets and spacecraft, including the IUE, the Pioneer Venus orbiter, and the HUT. Venus photographed in ultraviolet light by the Pioneer Venus Orbiter (Pioneer 12) spacecraft, Feb. 26, 1979. Venus also doesn’t do impact craters the same way the Earth or the Moon do. The new Venus photos mark the first time that a rainbow-like "glory" has been photographed on another world besides the Earth, officials with the European Space Agency (ESA) announced this month. Added colour in the image emulates Venus's yellow-white appearance to the eye. Unlike on Earth, where clouds tend to move only a few hundred miles at most, sulfuric acid clouds on Venus have ben seen moving from the poles to the equator, then back to the poles again, in just a few days.
