First discovered by the Voyager spacecraft in the early 1980s, NASA has recently released new images of the mysterious hexagon-shaped storm on Saturn’s northern pole. Taken with their Cassini Spacecraft, visible light images like this were not originally possible when Cassini arrived at Saturn back in 2004 due to the entire northern hemisphere being in winter solstice.
The hexagon measures 25,000 km (15,500 mi) across, with each side being 13,800 km (8,600 mi) long. As the above image demonstrates, it’s wide enough to fit nearly four earth’s inside of it.
The hexagonal ring itself is created by a jet stream, while the center contains a spiralling vortex of clouds. Scientists say that the storm reaches speeds up to 354 km/h (220 mph).
In short, we can’t figure it out. Namely, scientists don’t currently understand where the storm obtains and expels its energy, or how/why it has stayed in such an organized shape for so long.
