Saturn: January 2019



A new Southwest Research Institute study tackles one of the greatest mysteries about Titan, one of Saturn's moons: the origin of its thick, nitrogen-rich atmosphere.


Using new data from NASA's Cassini spacecraft, researchers believe they have solved a longstanding mystery of solar system science: the length of a day on Saturn. It's 10 hours, 33 minutes and 38 seconds.


The rings of Saturn may be iconic, but there was a time when the majestic gas giant existed without its distinctive halo.


Saturn's moon Titan is enveloped in a thick atmosphere, but through the infrared eyes of the international Cassini mission, the moon's myriad surface features are revealed in this exquisite global mosaic.
