Metallic hydrogen is one of the rarest materials on earth yet it makes up more than 80% of planets like Jupiter. Researchers at the the University of Rochester’s Laboratory for Laser Energetics created metallic hydrogen in the lab to study Jupiter’s magnetic field. The research has implications in planet formation and evolution, including how planets both inside and outside our solar system form magnetic shields. (NASA / JPL photo)

Liquid metallic hydrogen is not present naturally on Earth and has only been created in a handful of places. Now scientists are researching the properties of liquid metallic hydrogen to understand how planets both inside and outside our solar system form magnetic shields...

Physicists succeed in creating ‘the holy grail of high-pressure physics’. Nearly a century after it was theorized, Harvard scientists have succeeded in creating the rarest – and potentially one of the most valuable – materials on the planet. The material – atomic metallic hydrogen – was created by Thomas D. Cabot Professor of the Natural Sciences Isaac Silvera and post-doctoral fellow Ranga Dias. In addition to helping scientists answer fundamental questions about the nature of matter, the material is theorized to have a wide range of applications, including as a room-temperature superconductor.

“This is the holy grail of...
