A Japanese spacecraft sent back photos recently of what appears to be the largest wave of its kind known in the solar system.

The Akatsuki craft spotted the wave which stretched for more than 6,000 miles and remained fixed above the surface for four days. Researchers believe that the occurrence was a “gravity wave,” a “disturbance in the winds caused by the underlying topography that propagated upward.”
