What order do the Gundam seasons go in?

I have heard lots of titles called "Gundam" like, Gundam Seed, Gundam 00, but are these seasons, or are they all different animes? If they are seasons,thats fine, but what order do they go in? And if not seasons, can you give me a list of all the "Gundam" Series there are, and also put a star next to the one that's from this picture? a href="http://fc07.deviantart.net/fs38/f/2008/332/d/4/Setsuna_Marina_by_10721.jpg" rel="nofollow"http://fc07.deviantart.net/fs38/f/2008/3…/a thanks alot it really helps.
