5 stars for lecture anyway.

And the YouTube comments are pure, unadulterated awesomeness.

Post by Greenvalds:

"Europa has a very tenuous atmosphere consisting mostly of oxygen. - oxygen on Europa likely originates when charged particles from the Sun hit water molecules on Europas surface. The water molecules are broken into hydrogen and oxygen atoms, and sometimes recombine to form hydrogen and oxygen gas. Hydrogen, being less dense than oxygen, escapes more easily from Europas surface. Over time, the preferential escape of hydrogen has left behind a ghostly atmosphere of oxygen."

Reply from Szatmar666:

"LOL, O2 at 10^-11athmospheric pressure with mean surface temp of -160 C, very unlikely that the oceans dissolve that little O2 or that's enough 2 support life. What u have on EUR ocean at best is trace levels of O2 in the surface layers. On Earth the chem energy that support anaerobic bacteria around deep ocean vents cannot support multicellular life that feeds on it unless there is sufficient oxygen around them. On EUR there is no way that minuscule O2 can reach that deep or b that dense."

Science is dull without bad computer animation of freaky alien lifeforms.
