Dec. 22, 2022 As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How ...
May 10, 2021 Researchers show that, unlike the crystalline close packing of spheres, random close packing or jamming of spheres in a container can take place in a broad range of densities and anisotropies. ...
Mar. 4, 2021 Using data collected in a NASA wind tunnel, researchers replicated the hypersonic flow conditions of a compression ramp flow using Direct Numerical ...
Dec. 15, 2022 Scientists have designed and fabricated a simple device capable of imaging a gas injected into it in multiple colors in accordance with its gaseous properties, enabling chromatic discrimination of ...
Mar. 31, 2021 For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than cubic diamonds found in nature and often used in jewelry. Hexagonal diamonds have been found at ...
Nov. 25, 2021 Researchers have developed a jelly-like material that can withstand the equivalent of an elephant standing on it, and completely recover to its original shape, even though it's 80% ...
Nov. 16, 2021 Turbulence makes many people uneasy or downright queasy. And it's given researchers a headache, too. Mathematicians have been trying for a century or more to understand the turbulence that ...
Apr. 12, 2022 When triggered by some external agent, shockwaves can propagate through molecular clouds of gas and dust to create pockets of dense material. At a certain limit, that dense gas and dust collapses and ...
Mar. 15, 2022 Greenhouse gas emissions from air conditioners are expected to climb as economic growth drives efforts to control both temperature and humidity, according to a new ...
May 19, 2023 Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to ...
