Description

Venus, in the weeks before or after inferior conjunction, clearly shows the night side. Generally, we focus our attention in recording the blanket of clouds on the planet (UV and NIR), but the night side allows us to glimpse details of the surface of Venus, thanks to the phenomenon of the absorption bands of carbon dioxide (CO2), in near-infrared of the spectrum. The blanket of clouds of the planet can be drilled only in a "window" around 1000nm. Using CCD or webcam with high sensitivity in the infrared and filters of proven quality you can record this particular emissions.
