A spacecraft that recently arrived at Venus has confirmed the presence of an unusual storm feature—two giant, hurricanelike eyes within a storm at the planet's south pole.
The European Space Agency's Venus Express first observed the vortex soon after the craft entered orbit around Venus on April 11. Express' initial, distant path provided a global view of the planet, including a glance at the double vortex. In late May, the craft flew over the south pole and took a closer look at the storm.
Two previous missions to Venus more than 2 decades ago, Pioneer-Venus and Mariner 10, caught a glimpse of storms above the south pole, but the double-vortex pattern had never before been discerned.
