I like this work and the presentation by Tianlu Yuan (2013) about how our knowledge about the subject progressed -- the first photos were made by Voyager (1981-82): http://www-hep.colorado.edu/~tianlu/public/saturnHex_paper.p... http://www-hep.colorado.edu/~tianlu/public/saturnHex_present... "In the 1980s images of Saturn taken by Voyager led to Godfrey's surprising discovery
of a hexagonal structure on the planet's north pole [9]. Now, over three decades later,
Saturn's north polar hexagon remains, superficially unchanged and not entirely understood.
Voyager's iconic images proved a challenge to explain theoretically, but with additional data
from ground based observations and the HST in the early 90s, and images from the Cassini
mission more recently, our knowledge of many physical parameters forming the hexagon has
increased. Along with observation, laboratory experiments and numerical simulations have
helped foster greater understanding of the possible causes of the jet's six-sided shape." The more recent pictures (2016) are also interesting, as the color has changed(!): http://www.forbes.com/sites/startswithabang/2016/10/31/satur... And for completeness, the comics from 2010: http://www.smbc-comics.com/comic/2010-07-06 |
