Beerball Posted December 17, 2009 Share Posted December 17, 2009 how far is that in kilograms? link The star's modest surface temperature of 2,700°C, though, means that GJ1214b itself is a balmy 200°C. "suggests that GJ1214b is composed of about three-fourths water and other ices, and one-fourth rock". What ice will exist in 200oC?

bartshan-83 Posted December 17, 2009 Share Posted December 17, 2009 I don't know what the big deal is....I thought it was a pretty good movie. Link to comment Share on other sites More sharing options...
John Adams Posted December 17, 2009 Share Posted December 17, 2009 how far is that in kilograms? link What ice will exist in 200oC? (392oF) Areas of planet farther from star (like our poles). Mountain tops. Link to comment Share on other sites More sharing options...

I don't know what the big fuss is about. I saw that movie nine times. It rules! Link to comment Share on other sites More sharing options...

When I typed that, I thought for a second "Wait, this is familiar...maybe I'm stealing/butchering this line from someone else." Nice! Link to comment Share on other sites More sharing options...
Nervous Guy Posted December 17, 2009 Share Posted December 17, 2009 What ice will exist in 200oC? (392oF) duh...obviously it's Ice VII, a crystalline form of water that exists at pressures greater than 20,000 times Earth's sea-level atmosphere....dummy.

BillsWatch Posted December 17, 2009 Share Posted December 17, 2009 Just read the Bootnote The boiling point of water rises with pressure, so evidently GJ1214b has a surface pressure greater than 16 Bar, at which water boils at 200°C, according to this handy guide. This is something which most science fiction fans (not the kind with the space ships with lasers attacking ships going faster than light) understand. They have been a number of stories on planets with lower than earth pressure with settlers needing to adjust to changes like lower boiling point of water. Even on tall mountains it is a factor with hikers warned to check the temperature of item cooking for it may not be hot enough to kill germs.

And also, not all planets rotate on their axis such that every part of the planet may have portions that are permanently far from (not in the light of) the star, which could result in a much colder portion of the planet. And who has any idea how high a mountain is on that planet? It could be 10 miles high--plenty high to have ice formations. Link to comment Share on other sites More sharing options...
