The Venus Express, the European Space Agency's spacecraft dedicated to the exploration of our sister planet, has made this surprising discovery on its south pole: a massive vortex similar to the one found on Saturn's south pole.
Instead of finding a double storm system as expected, the spacecraft only found a single vortex. Scientists are trying to figure out how and why this is happening. The image - taken by the Venus Express' Visible and Infrared Thermal Imaging Spectrometer - shows the eye of the hurricane at 60km over the planet's surface. [ESA via It's Full of Stars]
