Waking a sleeping red giant

Better get your stuff done. Time's running out. Five-billion years from now, our sun will live out it's current stage of life. Having turned all the hydrogen in it's core into helium, it's outer layers of hydrogen will collapse into the center. The sun will become a red giant. In the process, it's core will heat and expand, it's radius will grow to 100 times it's size, and anything in the way, including Mercury and Venus, will be obliterated. But, according to a group of Italian astronomers, the Earth will be spared. The astronomers report that a nearby star called V 391 Pegasi has a planet orbiting it at about the same distance as we are to our sun. Remarkably, this planet has survived V 391 Pegasi's transformation to a red giant, so there's hope for Earth. Unfortunately, even though the Earth will survive, we will not. When the sun becomes a red giant, the intense heat and proximity of the sun will scorch the Earth and boil off the oceans. Perhaps within five-billion years, humans will have evolved into higher, purely spiritual beings, and we'll have no need for a planet anyway. link
