Saturn

  • Stormy Saturn
    As the Cassini mission approaches Saturn, the onboard cameras have begun to reveal the dynamic weather in the giant ringed world's cloud tops. In the southern hemisphere, new images show a brewing storm as two cells merge over several weeks.

  • Titan Casts X-ray Shadow
    The Chandra X-ray Telescope caught a rare event, the passage of Saturn's biochemically rich moon, Titan, in front of the x-ray bright Crab nebula. Astronomers seized the moment to make the first x-ray measurements of Titan's thick, smoggy atmosphere.

  • Saturn, Spot On
    As the Cassini-Huygens probe approaches Saturn, another stunning image of the moons surrounding this ringed world presents more mysteries as scientists seek to understand whether water circulation contributes to Saturn's cloud-top patterns.

  • Titan’s Southern Smile
    Observations taken atop the Chilean mountains reveal strange atmospheric patches on Saturn's largest moon, Titan. Although seen from the Hubble space telescope, the thick smog on Titan has proven a difficult photographic opportunity.

  • Titan’s Lapping Oil Waves
    Saturn's moon, Titan, is thought to harbor lakes of hydrocarbons. By modelling these waves using Titan's gravity, scientists predict seven times higher crests spaced widely apart compared to similar inputs on Earth.

  • Saturn in X-Rays
    The Chandra X-ray telescope shows that Saturn differs from Jupiter in whether its x-ray image is more intense at the poles or centered on the equator. This result has puzzled theorists since neither the x-ray intensity nor distribution fits any existing explanations.

  • Titan in a Test Tube
    Saturn's largest moon, Titan, has one of the most promising chemical laboratories for producing complex organic molecules. Experiments conducted in preparation for this summer's mission to probe Titan's astmosphere have tried to simulate its cold, prebiotic soup.

  • Saturnian Wheels Turn, Without Spokes
    As the Saturn probe, Cassini, approaches the ringed planet, its new images show a puzzling lack of 'spokes' that were first observed when Voyager flew by on its way to outer solar system. Planned to enter orbit in July, Cassini will drop a descent probe

  • Titan Ready to Lift Veil
    Reaching Saturn in July, the Cassini probe will orbit the ringed planet for four years. Five months after its first orbit, the probe will drop its lander on Saturn's moon, Titan--a biochemically rich world with black hydrocarbon lakes and chemical precursors for dishing up a

  • Lord of the Rings
    Missions to land on other planets benefit from the regular close approaches that neighboring worlds make in our solar system. The current blitz on Mars took advantage of a close approach in August, and this time next year, a lander descending on one of Saturn's

  • Ring Recycling
    One of the most beautiful and until recently least understood parts of our solar system was planetary rings. But since the Voyager spacecraft first discovered that tiny moons could shape or shepherd the rings on Saturn, a notion of the rings as rocky rubble has

  • Smog Warning, Titan
    The chemistry of Saturn's moon, Titan, has long fascinated planetary scientists, particularly since it was not only discovered to have a thick atmosphere, but also one rich in organics thought to have played important roles in Earth's early biochemistry. Is Titan's chemistry biochemical?

  • Titan’s Oily Lake
    Earth-based radio telescopes have penetrated the smog-covered moon of Saturn, called Titan. Underneath its thick atmosphere potentially resides the first evidence of a liquid hydrocarbon lake on its surface.

  • Titan Look at Saturn
    Only about three times a century can terrestrial observers get good view of underside or southern tilt of Saturn's rings. The Hubble Space Telescope capture seasonal change, and gives a preview of what might be in store when a lander attempts to penetrate biochemically-rich atmosphere

  • Titan’s Icy Bedrock
    Saturn's rich moon, Titan, has an orange, hazy atmosphere that resembles urban smog on Earth. But new findings suggest that beneath Titan's shroud are hints of a hydrological cycle and icy bedrock.
