Saturn system

  • Spying Spokes
    Delighted scientists on the Cassini imaging team will be breaking out the champagne in celebration of the first Cassini sighting of spokes, the ghostly radial markings discovered in Saturn's rings by NASA's Voyager spacecraft 25 years ago.

  • Gravity Assist Bumper Cars
    New observations from the Cassini spacecraft now at Saturn indicate the particles comprising one of its most prominent rings are trapped in ever-changing clusters of debris that are regularly torn apart and reassembled by gravitational forces from the planet.

  • Mysterious Enceladus
    Evidence is mounting that the atmosphere of Enceladus, first detected by the Cassini Magnetometer instrument, is the result of venting from ground fractures close to the moon's south pole. New findings from the close flyby of Enceladus by Cassini this past July add to the

  • Saturn’s Aurora
    New images of Saturn obtained by a University of Colorado at Boulder-led team on June 21 using an instrument on the Cassini spacecraft show auroral emissions at its poles similar to Earth's Northern Lights.

  • Saturnian Oxygen, Without Life
    Oxygen along with water are considered interesting biosignatures to look for when encountering other planets. On Saturn, the oxygen story can be misleading, if one speculates that its presence gives biology a leg-up.

  • Charged Up Over Saturn
    The four-year Cassini mission orbiting Saturn has as one of its main tasks to study the strange magnetic fields around the ringed world. Scientists are already concluding that the Earth's magnetic field is boring compared to the odd happenings they are seeing today near Saturn.

  • Dynamic Saturn Spawns Static
    Understanding the magnetic fields around Saturn represents one goal for the multiyear Cassini mission now orbiting the ringed world. How these fields are shaped by solar wind turns out to yield an aurora that shares many similarities to the Earth's familiar Northern Lights.
