That's why the true ideal place for humans to colonize is one of the "water" moons of Jupiter or Saturn. They're far enough out to escape the death of the Sun. Still have to deal with the low gravity problem however!

If we have descendants that survive, they probably won't be human anymore. And we'll still have the problem of no energy source in the solar system. Assuming Europa or Enceladus actually has liquid water (theorized, not assured), the life cycle is solar powered. No sun, no life. I can't rule out some as-yet unknown technology, but that does seem to be a basic limitation. Maybe we'll evolve into Vorlons, and not have to worry about such mundane things. :-)
