Planetary Atmospheres

[XMEN Wildchild]

Ok, put your thinking caps on and lend me a hand please. I know all of you are intelligent geeks so I need your input, you will be beat up later.<br><br>Now I am looking for information regarding different types of atmospheres. Obviously ours contains 77% nitrogen, 21% oxygen, and small amounts of argon and water vapor and other crap. (Gestimated on the percentages by reading online material so if its off forgive) <br><br>But what I am looking for is possible other and different atmospheres. Not just in our own solar system either. I know all of this will be speculation but does anyone know of or have a website linked that could help me out?<br><br>Thanks in advance to the Geekdom out there... <p><!--EZCODE CENTER START--><div style="text-align:center"><br>Proud Member of the<!--EZCODE ITALIC START--><em><!--EZCODE BOLD START--><strong>The Templars</strong><!--EZCODE BOLD END--></em><!--EZCODE ITALIC END--><br><br>Proud Member of <!--EZCODE ITALIC START--><em><!--EZCODE BOLD START--><strong>XMEN</strong><!--EZCODE BOLD END--></em><!--EZCODE ITALIC END--><br><br>Proud Sportscaster for the<!--EZCODE ITALIC START--><em><!--EZCODE BOLD START--><strong>TsN - The Team Sportscast Network</strong><!--EZCODE BOLD END--></em><!--EZCODE ITALIC END--><br><br>What we do today, Echoes in Eternity!<br><!--EZCODE BOLD START--><strong>ROMA VICT</strong><!--EZCODE BOLD END--></div><!--EZCODE CENTER END--></p><i></i>

You could probably find some serious discussion about that sort of thing in the realm of sci-fi, proposed and researched by people who know their stuff, but I'm not sure how to find it. I know Larry Niven was with a group for a while that developed entire sci-fi worlds, including inhabitants, in a scientifically consistent way. <p><!--EZCODE IMAGE START--><img src="http://www.xmenclan.org/xmengambit.gif"/><!--EZCODE IMAGE END--><br>XMEN member<br>Card-carrying DTM<br>OKL Fish-napper<br><br>Though a program be but three lines long, someday it will have to be maintained.<br><!--EZCODE ITALIC START--><em> The Tao of Programming</em><!--EZCODE ITALIC END--></p><i></i>

From what I understand planetary atmospheres can range from a huge list of things, but it basically boils down to what went into the primordial soup that made up the planet, as well as how long it baked for (ie what the temperature is, also where its located to the "sun" and how hot/what type of star it is) along with the mass of the planet.<br><br>doing a quick search on GOOGLE I came up with these sites<br><br><!--EZCODE LINK START--><a href="http://zebu.uoregon.edu/~js/ast221/lectures/lec14.html" target="top">zebu.uoregon.edu/~js/ast221/lectures/lec14.html</a><!--EZCODE LINK END--> Note you can also dump the lec14.html and look at the other lectures<br><br>I would post more links however seems my internet just farted so I get to save this message to a file, then reboot (which sucks because I lost my place in line for downloading the T:V single player demo)<br><br>But anyways do a search on google for planetary atmosphere comparison (or other things along those lines) I got a bunch of good looking prospects, but can't look at them untill after I reboot and franky by then I will have lost interest so good luck <!--EZCODE EMOTICON START :) --><img src=http://www.ezboard.com/images/emoticons/smile.gif ALT=":)"><!--EZCODE EMOTICON END--> <p></p><i></i>

If you take pretty much every element from the periodic table, from hydrogen to about uranium, you'll always have gaseous forms of those elements or compounds with those elements in the atmosphere. Of course it depends on what the planet's conditions are (temp, mass, distance from sun, life, etc.) Plus, a planets own atmospheric composition influences what can exist in it and what can't. For example, you'll never find an atmosphere like ours (temp and density wise) that is filled with chlorine gas and sodium gas. The two gases will react violently with each other and form salt. The only way to have both is to have the planet so hot that it's either very volcanically active, or very close to its sun. In either case, the atmosphere isn't going to stay the same for long.<br><br> <p></p><i></i>
