Earthlike Treats

White Dwarfs Gobble Earthlike Treats

Astronomers have detected the chemical signatures of rocky, earthlike planets that have been consumed by their dying stars. These white dwarfs once were red giants, consuming the inner planets of their solar systems. This will be the ultimate farewell for our earth one day as our sun will become a red giant and engulf the inner planets, possibly including our own planet. One cool thing this finding shows, is that inner rocky planets are more probable now across the galaxy and the universe than previously thought. Our solar system may be more run of the mill tat we used to think. There may be many other systems like our with inner rocky planets and outer gas planets.
