Much of the surface of Venus appears to be rather young. The global data set from radar imaging reveals a number of craters consistent with an average Venus surface age of 300 million to 500 million years. There are two continents, which are large regions several kilometers above the average elevation.
Venusâ climate I: How scientists know Venusâ surface is unusually hot (corrected) Ultraviolet image of Venusâ clouds as seen by the Pioneer. Venus Orbiter, Feb. 26, 1979 (NASA). Scientists have known that the surface of Venus is extremely hot since the first probes flew by the planet in the 1960s. Venusâ hot surface is presently understood to be a direct result of the composition of the atmosphere â Venusâ atmosphere is nearly 97% carbon dioxide (CO2). CO2 is known to be a greenhouse gas, and the same optical properties that make it a greenhouse gas are whatâs responsible for Venusâ high surface temperature.
