Imaggeo on Mondays: Entangled
South auroral oval and polar rain simulated in laboratory using the Planeterrella experiment (J. Lilensten et al., UJF/CNRS, Grenoble, France, online). The Planeterrella was redesigned after K. Birkeland’s original terrella experiments, which in the 1900s helped him unveil the mechanisms at the origin of polar aurorae. A magnetised aluminium sphere is placed in a vacuum chamber. An electric ...[Read More]
