Good news, bad news

The bad news is… that in about 5 Billion years our sun is going to start burning helium (because its run out of hydrogen)… turning our nice yellow star into an expanding red giant. It will consume Mercury and Venus… and turn the earth into an uninhabitable pool of slag. (assuming we haven’t done this already on our own… being competitive I mean)

The good news is, that the moons of Saturn and Jupiter will now be in the habitable zone and are likely to remain so for about half a billion years. Yay us!
