Completely New Type of Magnetic Wave Discovered Sweeping Across Earth’s Outer Core

[ad_1] Using information from ESA’s Swarm satellite mission, scientists have discovered a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years. This fascinating finding opens a new window into a world we can never see. This mysterious wave oscillates every seven years and propagates westward […]

Electrons Surfing on Alfvén Waves

[ad_1] By U.S. Department of Energy April 30, 2022 As electrons accelerated by Alfvén waves stream along the Earth’s magnetic field (yellow drops), they collide with oxygen atoms (white dots) and molecules of oxygen and nitrogen (white dumbbells) and cause them to emit light and create the auroras.

New Insight Into “Blobs” Improves Scientists’ Understanding of a Universal Process

[ad_1] Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have gained insight into a fundamental process found throughout the universe. Scientists have found that the magnetic fields that run through plasma, a charged state of matter made up of free electrons and atomic nuclei, may influence the joining and violent […]

Modeling Earth’s Magnetosphere in the Laboratory

[ad_1] Experimental platform combines Large Plasma Device with lasers, magnetic dipoles; reveals insights about Earth’s shield against solar wind. A magnetosphere forms around any magnetized object, such as a planet, that is immersed within a stream of ionized gas, called plasma. Because Earth possesses an intrinsic magnetic field, the planet is surrounded by a large […]
