Hubble Finds Dead Stars ‘Polluted’ with Planet Debris
NASA’s Hubble Space Telescope has found the building blocks for Earth-sized planets in an unlikely place, the atmospheres of a pair of burned-out stars called white dwarfs. The dwarfs are being polluted by asteroid-like debris falling onto them. This discovery suggests that rocky planet assembly is common in stars, say researchers.
The white dwarfs reside 150 light-years away in the Hyades star cluster, residing in the constellation Taurus the Bull. The cluster is relatively young, only 625 million years old.
