 One of the really exciting and high-level scientific interests is whether Venus is geological active today, because there are reasons to think of the clouds on Venus only exist, because there is ongoing geological activity, so this is one of the biggest secrets of Venus, something that we want to find out.

In recent years, finding the source of Venus’ thick atmosphere has become surprisingly relevant for all of us down here on earth.
 
Half a million tons of sulfur dioxide are spewed into/ the atmosphere every year.
 
The whole greenhouse effect was not really recognized as a significant effect to influence/ planetary climates until we went to Venus and found that’s said to be in 90 degrees Fahrenheit to 900 degrees Fahrenheit. 
 
And we said, wow, what's wrong with this. Learned about this and it taught us about the greenhouse effect.
 
Ever wonder how alien a planet could be, how bad a climate can get? Try the planet next door. The best way to experience Venus is to hitch an imaginary ride on the Soviet Venera Probe.
