    Mean winds at the cloud top of Venus obtained from two-wavelength UV imaging by Akatsuki

    Venus is covered with thick clouds. Ultraviolet (UV) images at 0.3–0.4 microns show detailed cloud features at the cloud-top level at about 70 km, which are created by an unknown UV-absorbing substance. Images...
