Dying Stars Caught Snacking On The Vaporized Crusts Of Earth-Like Planets They Destroyed – IFLScience

Astronomers have detected the vaporized remnants of Earth-like planetary crusts in the atmosphere of four nearby white dwarfs, the final stage of evolution for stars up to 10 times the mass of our Sun. These incredible observations suggest that rocky planets like Earth and Mars form roughly in the same way across the galaxy and also rather quickly.
Reporting in the journal Nature Astronomy, the team found the outer layers of the white dwarfs to contain an estimated 300,000 gigatonnes of rocky debris,…
