White dwarfs gobble Earthlike treats


Marcus G. -- Scientist have found remains of planets with some earth like qualities near white dwarf stars. Which is actually where astronomers would not look at for signs of life. Even more interesting is that they were also around the same distance from the used to be star as with Earth and our star. How they were able to find this is that the would study the pollution of the star to see what elements and such to tell what was there. This is shocking to many astronomers and scientist, because for years all white dwarf stars do was suck up pollution before it finally died. They have found a star that was taking in oxygen, magnesium, silicon, and iron. Which is very similar to the properties of Earth.
This is really interesting to me. Especially that astronomers usually don't find things like this with white dwarf stars. Even if the planet is gone it still gives us a insight on where we my find traces of Earthlike planets.  Stars are fascinating to me. they have so much power and energy. Some may explode in a huge supernova then become a crushing black hole, or become a red giant and destroy anything to close only then to turn into a white dwarf and finally to nothing. I didn't think such remarkable discoveries could come from looking at dying stars.
