“A major role of the atmosphere was to filter out the ionising radiation from the sun by ionising the high atmosphere and forming the ionosphere.”

“The pressure distribution within the magnetic barrier just outside the ionopause of Venus is shown here to be similar to expected solar wind pressure variation.”
