&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&lt;br /&gt;
If Saturns moon [[Titan (giant moon)|Titan]] is just a tiny bit too warm to have a global liquid nitrogen ocean &amp;lt;br&amp;gt; &lt;br /&gt;
then there must be plenty of worlds (moons and planets) out there in our galactic vicinity that actually do have such a liquid nitrogen ocean. Right? &amp;lt;br&amp;gt;&lt;br /&gt;
Isn&amp;#039;t that a fascinating Idea?&lt;br /&gt;
&lt;br /&gt;
Methane freezes (90.694 K) before nitrogen condenses (77.355 K). &amp;lt;br&amp;gt;&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Q:&amp;#039;&amp;#039;&amp;#039; What is the density of frozen methane? Will it float or sink (or dissolve)?&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Q:&amp;#039;&amp;#039;&amp;#039; If Titans atmosphere would condense (thought experiment) how thick of an ocean would it make?&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Q:&amp;#039;&amp;#039;&amp;#039; When our sun was young and cool how close was Titan to having an lN&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt; ocean? Did Titan actually have one in the far past??&lt;br /&gt;
&lt;br /&gt;
Nitrogen:&lt;br /&gt;
* Boiling point: 77.355 K&lt;br /&gt;
* Density ~0.8g/ccm&lt;br /&gt;
&lt;br /&gt;
== Even more exotic cold oceans ==&lt;br /&gt;
&lt;br /&gt;
=== Mehane oceans ===&lt;br /&gt;
&lt;br /&gt;
Would that be possible? &amp;lt;br&amp;gt;&lt;br /&gt;
[[Titan (giant moon)|Titan]] has only a few lakes.&lt;br /&gt;
&lt;br /&gt;
=== Hydrogen-Helium oceans (probably not anytime soon) ===&lt;br /&gt;
&lt;br /&gt;
A liquid hydrogen-helium ocean for rouge planets between the stars seems much more unlikely &amp;lt;br&amp;gt;&lt;br /&gt;
since planets need to be huge to gather these light elements and once gathered these big planets need to give of fromation heat for a long long time.&lt;br /&gt;
The pressure needs to go below the critical point (13bar for hydrogen) to get liquid like sharp surface.&lt;br /&gt;
If this really happens in a far far future dark and dead universe, condensed liquified gas giants would really be strange places.&lt;br /&gt;
