When the sun dies, the oceans will be boiled off the surface of the Earth... If 
there is life on Europa, it might survive for a while, since the tidal forces 
from Jupiter might keep it hot.

Actually, there are ecosystems on the sea floor that exist entirely 
independently of the Sun. Heat (geothermal) and nutrients (such as sulfur 
compounds and methane) are provided by hydrothermal vents, and chemosynthetic 
(rather than photosynthetic) microbes provide the base of the food chain. These 
ecosystems include not just chemosynthetic microbes, but a diverse array of 
invertebrates (clams, shrimp, and> various types of worms). If the Sun died 
out, these organisms would> presumably go on living. It's even possible that 
life at the hydrothermal systems on the Earth's surface would outlive the death 
of the Sun - including those> at Yellowstone. The humans and buffaloes would 
kick the bucket, but hydrothermal microbes might very well be untouched.
