Earth Won't Be Swallowed When the Sun Dies
Here's a piece of good news: the Earth won't be consumed by the Sun when it begins to die in 7.5 billion years. When stars like the Sun near death, they to expand many times their original size and become a red giant star. Astronomers originally calculated that the Sun will consume inner planets, including the Earth as it expands, but new research has given our planet a reprieve. As the Sun expands it will also shed material decreasing its gravitational hold on the Earth, spiraling our planet's orbit away from the sun. So, we won't actually be consumed, just burned to a crisp, radiated, and then frozen when the Sun shrinks again. Whew.
