White dwarf stars are the stellar cores left behind by Sun-like stars after they have exhausted their nuclear fuel. Some of these dead stars still have rocky bodies orbiting them that are similar to our asteroids. These orbiting objects sometimes fall into the stellar atmosphere and vaporize, releasing their elements which then contribute to the spectral lines visible with telescopes.

The chemical similarities between rocks in our solar system and the rock-forming elements floating in the atmospheres of white dwarf stars provide good evidence that rocky planets elsewhere in the Milky Way Galaxy are similar to the rocky planets in our solar system. This, in turn, suggests that Earth-like planets are not unusual.
