Our Sun will expand outwards when its nuclear fuel runs low and will ultimately blow off its outer layers. Some of the inner planets will be consumed in the process and asteroids will be thrown out of their orbits. Read more

Asteroid debris is 'raining' into the hot atmospheres of these white dwarfs. Asteroids should consist of the same material that form terrestrial planets, and seeing evidence of asteroids points to the possibility of Earth-sized planets in the same system. Read more
