- Mar 9, 2004The 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.
- Mar 1, 2004Saturn'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.
- Feb 27, 2004As 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
- Feb 18, 2004Reaching 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
- Oct 28, 2003The 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?
- Sep 10, 2003Only 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
- Mar 21, 2003How will the most favorable conditions for life move outward as the Sun enters its brighter, red giant phase? Paleontologist Peter Ward and astronomer Robert Brownlee take a voyage of imagination seven billion years into the future, and come back with a new and distant
