Title: How would an observer from Earth see the next phase of the sun's life?

Assuming they did not die and that they are facing the sun. What would it look like? How would it seem to them - would they be engulfed by light before they were scorched?

I'm not sure, but i would imagine they would see it expand as though it where approaching them. Color will change (but this expansion is by no feat a quick process) I would have imagined.

I would have also imagined that the light would indeed be too intense as the star enlarged; our eyes simply are not created for that kind of radiation. In attempts to observe it in its late stellar evolution would most probably blind us.

not with eclipse glasses [;)]

Anyhow, wouldn't the expansion phase go so slowly that there's no noticeable difference over 150 years? [let's assume that's the average lifespan of a human by then...]

I would have thought.
