lightning raining down on the surface the whole time. The storm lasted for 267 days! Along with amazing photographs of the massive storm, Cassini’s near infrared camera detected a combination of water and ammonia ice in the storm clouds. The storm ended when the head of the storm ran into its own “tail” after encircling the planet and the circulation eventually came to a stop. Another recent discovery is that Saturn’s moon, Enceladus, has an ocean of liquid water beneath its frozen crust. of liquid below the surface when a Cassini Flyby in 2005 showed water vapor and ice spewing from vents near the moon’s south pole. Scientists recently provided more evidence of this ocean’s existence by measuring the gravitational variances of the moon. Utilizing data from three has
