Saturn's stunning double show (4x1)

Data di messa in onda: Feb 11, 2010

In January and March 2009, researchers using Hubble took advantage of a rare opportunity to record Saturn when its rings are edge-on, resulting in a unique movie featuring both of the giant planet's poles. Saturn is only in this position every 15 years or so and this favourable orientation has allowed a sustained study of the two beautiful and dynamic aurorae, Saturn's own northern and southern lights.
