I was stumbling about esa.int in the vain search for some sign of live streaming coverage of the Jules Verne launch on Sunday when I came across this beautiful and hypnotic movie, showing the top layers of the atmosphere being blown away by the solar wind.

Note, however, that Venus has about 4x as much Nitrogen in it's atmosphere as Earth does. As a percentage, yes, it's a lot lower, but because Venus has such a thick atmosphere, it still works out to much more Nitrogren in toto. In fact, unless I've missed a decimal point somewhere, Venus even has twice as much water vapor as Earth does.
