Context:

  • The long-lived international Cassini mission has revealed a surprising feature emerging at Saturn’s northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin to the famous hexagon seen deeper down in Saturn’s clouds. This suggests that the lower-altitude hexagon may influence what happens up above, and that it could be a towering structure spanning hundreds of kilometres in height.
  • The vortex is akin to the famous hexagon seen deeper down in Saturn’s clouds, according to the finding published in the journal Nature Communications. 
  • The results suggest that the lower-altitude hexagon may influence what happens above, and that it could be a towering structure hundreds of miles in height. 

NASA’s Cassini

  • The Cassini–Huygens mission, commonly called Cassini.
  • Launched in 1997.
  • It was a collaboration between NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI).
  • To send a probe to study the planet Saturn and its system.
  • Including its rings and natural satellites.
  • The Flagship-class robotic landed on Saturn’s largest moon, Titan in 2005.
  • Cassini was the fourth space probe to visit Saturn and the first to enter its orbit.
