Astonishing news,
I'm really surprised to see that a moon 10 times as small as Titan in diameter ( 500 km ) is able to generate so much energy from its interior. It should be a dead world, like our moon. We have now a strong evidence that a subsurface ocean is a possibility beneath this icy crust.But, how deep is this icy crust? Someone has concluded that the temperatures in the south polar grooves from which the vapor is ejected might reach 300 k, that is 26.85°C or 80.33°F. www.titanexploration.com |
