New insight into Earth’s crust, mantle and outer core interactions

Inside the target chamber at the University of Rochester's Omega Facility, a team of researchers including Princeton University's Thomas Duffy and June Wicks use lasers to compress iron-silicon samples to the ultrahigh pressures found in the cores of super-Earths.

Challenging core belief: Have we misunderstood how Earth’s solid center formed?

Earth experienced multiple large impacts; the high-pressure and -temperature conditions caused pockets of core and mantle partitioning that persist as chemically distinct today.
