Recently hubble managed to find CO2 and CO in the atmosphere of a gas giant afther it also had found H20 and CH4.

This is rather interesting because no Gas giant in our solar system seems to have any CO2 and actually if you took CO2 and added large amounds of H2 it would decay into H20 and C... how can there be CO2 in a gas giant?

The next big mystery is to find out why Methane is present in the martian atmosphere? Forget about the cud crunching martian cows and Methane belching (from the opposite end) martian elephants. The scientists down here on Earth won't buy that one.

The make up of planets depend on where they form in a solar system. Planets close in have lots of heavier elements while planets further out have lighter elements. This is confused some in that in formation, giant planets can slingshot smaller planets inwards or outwards in a solar system before it settles down. The gas giant here is too hot for life so was formed close in to the sun so would have heavier elements than cold Jupiter and Saturn would have in it's makeup. Possibly the planet has organic molecules though the heat would mean long chain ones would be unstable and so not form.

NASA believes there may be bacterial life under Mars which is the only explanation they can come up for as to why there is methane on Mars (if from a cometary impact, it would vanish in less than two centuries).
