Argonne's powerful X-rays key to confirming water source deep below Earth's surface

March 26, 2018

A study published in Science last week relies on extremely bright X-ray beams from the U.S. Department of Energy's Advanced Photon Source at Argonne National Laboratory to confirm the presence of naturally occurring water at least 410 kilometers below the Earth's surface. This exciting discovery could change the understanding of how water circulates deep in the Earth's mantle and how heat escapes from the lower regions of the planet. Full Story
