Given current technology and information, what will ultimately be the death of our solar system?

The Solar System will die when the Sun becomes a red giant star whose outer envelope reaches as far out as Venus, or perhaps even the Earth. Even if the envelope doesn't reach the Earth, the immense radiation given off by the Sun in this phase will eliminate all life on the planet. The Sun will then transition to a white dwarf star and slowly cool for the rest of time. Interactions with the material given off by the Sun during the red giant to white dwarf transformation may disrupt the outer planets as well.
