As auroras de Saturno (Hubble)

Citando:
"Astronomers using the ESA Hubble Space telescope took a series of shots using ultraviolet light, resulting in composites that show a wider range of light than humans can see with the naked eye.

NASA described them as "the most comprehensive picture so far of Saturn’s Aurora Borealis".

The images were taken last year over a period of seven months, as the Hubble's Space Telescope Imaging Spectrograph allowed scientists to monitor the behaviour of the auroras for an extended period."

Citando:
"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."

Sonda Cassini entra nos anéis de Saturno - NASA

Entre aspas, ou talvez não. Na fase final os anéis vão ser estudados de perto. A 15 de Setembro (menos de daqui a um ano) termina a missão com um mergulho final em Saturno:
