During the Cassini mission, the hexagon changed from a mostly blue color to more of a golden color. Saturn's south pole does not have a hexagon, as verified by Hubble observations.
A hexagonal cyclone in Saturn's north pole has been spotted since the passage of Voyager 1 and 2, and was first imaged by Cassini on January 3, 2009. [25] It is just under 24,000 km (15,000 mi) in diameter, with a depth of about 100 km (60 mi), and encircles the north pole of the ringed planet at roughly 78° N latitude.

This is a demonstration of the message with color added to highlight its separate parts. The binary transmission sent carried no color information. The Arecibo message is an interstellar radio message carrying basic information about humanity and Earth that was sent to the globular cluster Messier 13 in 1974. It was meant as a demonstration of ...
