Strange New State of Hydrogen Created

By crushing Earth’s lightest element with mind-boggling pressures, scientists have revealed an entirely new state of matter: phase V hydrogen.

The squished hydrogen is a precursor to a state of matter first proposed in the 1930s, called atomic solid metallic hydrogen. When cooled to low enough temperatures, hydrogen (which on Earth is usually found as a gas) can become a solid; at high enough pressures, when the element solidifies, it turns into a metal. Planetary scientists think the interior of Jupiter is largely made of the stuff.

Liquid hydrogen is created routinely in industry at cryogenic temperatures with pressures in the tens of atmospheres, but nobody has yet cooled the element enough to solidify it

There’s another aspect to this. Metallic hydrogen is the first example of “degenerate matter” made on earth. Degenerate matter, as all should know, is what white dwarf stars are made from.
