This May 4, 2014, file image made available by NASA shows the persistent hexagonal cloud pattern on Saturn's north pole, as seen from the Cassini spacecraft. The hexagon is similar to Earth's polar vortex, which has winds blowing in a circular pattern around the polar region, and is nearly 25,000 kilometers (15,000 miles) across. Nearly four Earths could fit inside it. (NASA/JPL-Caltech/Space Science Institute via AP)
