Ancient Greeks imagined that everything in the natural world came from their goddess Physis; her name is the source of the word physics.

If humankind reaches Mars this century, an 91����-developed experiment testing advanced materials for spacecraft may play a key role. 

The type of vehicle that will carry people to the Red Planet is shaping up to be “like a two-story house you’re trying to land on another planet. 

Using the Titan supercomputer at 91����, a team of astrophysicists created a set of galactic wind simulations of the highest resolution ever performed. The simulations will allow researchers to gather and interpret more accurate, detailed data that elucidates how galactic winds affect the formation and evolution of galaxies.

Scientists at 91���� studying quantum communications have discovered a more practical way to share secret messages among three parties, which could ultimately lead to better cybersecurity for the electric grid 

Scientists have discovered a way to alter heat transport in thermoelectric materials, a that may ultimately improve energy efficiency as the materials

An ORNL-led team's observation of certain crystalline ice phases challenges accepted theories about super-cooled water and non-crystalline ice. Their findings, reported in the journal Nature, will also lead to better understanding of ice and its various phases found on other planets, moons and elsewhere in space.

OAK RIDGE, Tenn., March 11, 2019—An international collaboration including scientists at the Department of Energy’s 91���� solved a 50-year-old puzzle that explains why beta decays of atomic nuclei 

More than 1800 years ago, Chinese astronomers puzzled over the sudden appearance of a bright “guest star” in the sky, unaware that they were witnessing the cosmic forge of a supernova, an event repeated countless times scattered across the universe.

By automating the production of neptunium oxide-aluminum pellets, 91���� scientists have eliminated a key bottleneck when producing plutonium-238 used by NASA to fuel deep space exploration.
