Argon found in air of ancient atmosphere

On the massive sheets of ice that stretch across Greenland and Antarctica, the temperature is so low that not even the summer sun can melt the snow deposited onto them. As the snow accumulates without melting and settles ...

A test firing of Europe's Helicon Plasma Thruster, developed with ESA by SENER and the Universidad Carlos III's Plasma & Space Propulsion Team (EP2-UC3M) in Spain. This compact, electrodeless and low voltage design is ideal ...

A (much) earlier birth date for tectonic plates

Yale geophysicists reported that Earth's ever-shifting, underground network of tectonic plates was firmly in place more than 4 billion years ago—at least a billion years earlier than scientists generally thought.

How to produce the purest argon ever

CERN is taking part in a project, called ARIA, for the construction of a 350-metre-tall distillation tower that will be used to purify liquid argon (LAr) for scientific and, in a second phase, medical use.

Capturing high pressures in diamond capsules

Preservation of the high-pressure states of materials at ambient conditions is a long-sought-after goal for fundamental research and practical applications.
