Worlds in Collision
Tim Callahan, religion editor of "Skeptic", presses the case further in claiming that the composition of the atmosphere of Venus is a complete disproof of "Worlds in Collision". "...Velikovsky's hypothesis stands or falls on Venus having a reducing atmosphere made up mainly of hydrocarbons. In fact, the atmosphere of Venus is made up mainly of carbon dioxide—carbon in its "oxidized" form—along with clouds of sulfuric acid. Therefore, it couldn't have carried such an atmosphere with it out of Jupiter and it couldn't be the source of hydrocarbons to react with oxygen in our atmosphere to produce carbohydrates. Velikovsky's hypothesis is falsified by the carbon dioxide atmosphere of Venus."
Titan Winged Aerobot
Titan is the only moon with an atmosphere, and its atmosphere is the only known nitrogen-rich atmosphere in the Solar System. The observations from Voyager and Cassini–Huygens shows that its atmosphere is denser than earth with the atmospheric pressure of 1.45 atm . It is 1.9 times as massive as Earth overall.
