An article published in the journal “Geophysical Research Letters” describes the discovery of an electric wind on Venus that accelerates the ionized hydrogen and oxygen atoms that make up water molecules at such a speed that they disperse in space. A team of scientists led by Glyn Collinson, a scientist of NASA’s Goddard Space Flight Center, analyzed data from the ASPERA-4 instrument of ESA’s Venus Express space probe to find out this wind generated by Venus’ electric field.
