Watch World’s First Live 360 Degree Video of Rocket Launch April 18

NASA, in coordination with United Launch Alliance (ULA) and Orbital ATK, will broadcast the world’s first live 360-degree stream of a rocket launch.

Study unravels long-held Fermi puzzle tied to nonlinear systems

In physics, the Fermi-Pasta-Ulam-Tsingou (FPUT) problem—which found that certain nonlinear systems do not disperse their energy, but rather return to their initial excited states—has been a challenge that scientists have tackled repeatedly since 1955.

Pulsed ion beams reveal nonlinearity of radiation defect dynamics in silicon carbide

Materials scientists at Lawrence Livermore National Laboratory (LLNL) got a step closer to understanding defect interaction dynamics in silicon carbide.

NASA Awards Commercial Payload Processing Contract

NASA has selected Astrotech Space Operations, LLC, of Titusville, Florida, to provide commercial payload processing services for agency missions launching from NASA’s Kennedy Space Center and Cape Canaveral Air Force Station in Florida.

NASA Missions Provide New Insights into 'Ocean Worlds' in Our Solar System

Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other "ocean worlds" in our solar system and beyond. The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescop

Battery prototype powered by atmospheric nitrogen

As the most abundant gas in Earth's atmosphere, nitrogen has been an attractive option as a source of renewable energy. But nitrogen gas doesn't break apart under normal conditions, presenting a challenge to scientists who want to transfer the chemical energy of its triple bond into electricity. Researchers present one approach to capturing atmospheric nitrogen that can be used in a battery.

Green IT: New switching process in non-volatile spintronics devices

Physicists achieved a robust and reliable magnetization switching process by domain wall displacement without any applied fields. The effect is observed in tiny asymmetric permalloy rings and may pave the way to extremely efficient new memory devices. The results have been published in Physical Review Applied, highlighted as an Editors' Suggestion.

A quantum low pass for photons

Physicists have observed a novel quantum effect that limits the number of emitted photons, outlines a new report.

LArIAT upgrade will test DUNE design

In particle physics, the difference of a millimeter or two can make or break the experiment. In March, the LArIAT experiment began a proof-of-concept test to make sure the planned Deep Underground Neutrino Experiment (DUNE) will work well with that 2-millimeter difference.

The most accurate measurement of rare meson decay confirms modern physics

All physical theories are simplified representations of reality, and as a consequence, have a specified range of applicability. Many scientists working on the LHCb experiment at CERN had hoped that the exceptional accuracy in the measurement of the rare decay of the Bs0 meson would at last delineate the limits of the Standard Model, the current theory of the structure of matter, and reveal phenomena unknown to modern physics. But the spectacular result of the latest analysis has only served to extend the range of applicability of the Standard Model.
