Clouds Venusian clouds are thick and are composed of sulfur dioxide and droplets of sulfuric acid. [29] These clouds reflect about 75% [30] of the sunlight that falls on them, which is what obscures the surface of Venus from regular imaging. [1] The reflectivity of the clouds causes the amount of light reflected upward to be nearly the same as that coming in from above, and a probe exploring the cloud tops could harness solar energy almost as well from below as above, enabling solar cells to be fitted just about anywhere. [31] The cloud cover is such that very little sunlight can penetrate down to the surface, and the light level is only around 5,000–10,000 lux with a visibility of three kilometres. At this level little to no solar energy could conceivably be collected by a probe. Humidity at this level is less than 0.1%. [32] In fact, due to the thick, highly reflective cloud cover the total solar energy received by the planet is less than that of the Earth. Photograph taken by the
