On Mars, winds constantly stir up whirlwinds of fine dust. It was at the center of two of these dust devils that the SuperCam instrument’s microphone, the first ever to operate on Mars, accidentally recorded particularly strong signals.
\nAnalyses carried out by scientists at the Institut de recherche en astrophysique et plan\u00e9tologie (CNES\/CNRS\/Universit\u00e9 de Toulouse) and the laboratoire Atmosph\u00e8res et observations spatiales (CNRS\/Sorbonne Universit\u00e9\/Universit\u00e9 de Versailles Saint-Quentin-en-Yvelines) showed that they were the electromagnetic and acoustic signatures of electric discharges comparable to the small static electricity shocks that can be experienced on Earth when touching a door handle in dry weather. Long theorized, the existence of electric discharges in the Martian atmosphere has now been confirmed by observation for the first time.
\nThese phenomena can be explained by friction between tiny dust particles: they become charged with electrons and then release their charges in the form of electric arcs a few centimeters long accompanied by audible shock waves.<\/p>\n","protected":false},"excerpt":{"rendered":"
