(PhysOrg.com) -- If a suggestion to be made to NASA comes to fruition, vast lakes thought to be filled with liquid hydrocarbons near the north pole of Saturn's moon Titan, may one day be explored by boat. http://www.physorg.com/news180680793.html Space & Earth Tue, 22 Dec 2009 07:10:01 EST news180680793 (PhysOrg.com) -- NASA's Cassini Spacecraft has captured the first flash of sunlight reflected off a lake on Saturn's moon Titan, confirming the presence of liquid on the part of the moon dotted with many large, lake-shaped basins. http://www.physorg.com/news180296862.html Space & Earth Thu, 17 Dec 2009 18:28:54 EST news180296862 (PhysOrg.com) -- Scientists once thought that life could originate only within a solar system's "habitable zone," where a planet would be neither too hot nor too cold for liquid water to exist on its surface. But according to planetary scientist Francis Nimmo, evidence from recent NASA missions suggests that conditions necessary for life may exist on the icy satellites of Saturn and Jupiter. http://www.physorg.com/news180112635.html Space & Earth Tue, 15 Dec 2009 18:55:19 EST news180112635 (PhysOrg.com) -- When it flies by Saturn's largest moon, Titan, this weekend, NASA's Cassini spacecraft will study the interactions between the magnetic field of Saturn and Titan. The flyby will take place the evening of Dec. 11 California time, or shortly after midnight Universal Time on Dec. 12. http://www.physorg.com/news180032789.html Space & Earth Mon, 14 Dec 2009 17:40:02 EST news180032789 Extensive analyses and modeling of Cassini imaging and heat-mapping data have confirmed and extended previous ideas that migrating ice, triggered by infalling reddish dust that darkens and warms the surface, may explain the mysterious two-toned "yin-yang" appearance of Saturn's moon Iapetus. The results, published online Dec. 10 in a pair of papers in the journal Science, provide what may be the most plausible explanation to date for the moon's bizarre appearance, which has puzzled astronomers for more than 300 years. http://www.physorg.com/news179677088.html Space & Earth Thu, 10 Dec 2009 14:18:55 EST news179677088 (PhysOrg.com) -- After waiting years for the sun to illuminate Saturn's north pole again, cameras aboard NASA's Cassini spacecraft have captured the most detailed images yet of the intriguing hexagon shape crowning the planet. http://www.physorg.com/news179601566.html Space & Earth Wed, 09 Dec 2009 17:50:03 EST news179601566 (PhysOrg.com) -- The annual Geminid meteor shower, which will reach its maximum on the night of Dec. 13-14, usually offers the best show of the year, outperforming even the Perseid shower of August. This year the Geminids will peak three days after new moon, so viewing conditions should be favorable. In a clear sky, observers may see more than 100 meteors per hour. http://www.physorg.com/news179085646.html Space & Earth Thu, 03 Dec 2009 19:00:01 EST news179085646 Researchers at the California Institute of Technology (Caltech) suggest that the eccentricity of Saturn's orbit around the sun may be responsible for the unusually uneven distribution of methane and ethane lakes over the northern and southern polar regions of the planet's largest moon, Titan. On Earth, similar "astronomical forcing" of climate drives ice-age cycles. http://www.physorg.com/news178724806.html Space & Earth Sun, 29 Nov 2009 13:49:18 EST news178724806 (PhysOrg.com) -- The diminutive moon Prometheus whips gossamer ice particles out of Saturn's F ring in this image taken by the Cassini spacecraft on Aug. 21, 2009. http://www.physorg.com/news178393307.html Space & Earth Wed, 25 Nov 2009 18:10:01 EST news178393307 (PhysOrg.com) -- In the first video showing the auroras above the northern latitudes of Saturn, Cassini has spotted the tallest known "northern lights" in the solar system, flickering in shape and brightness high above the ringed planet. http://www.physorg.com/news178303936.html Space & Earth Tue, 24 Nov 2009 16:53:17 EST news178303936 (PhysOrg.com) -- NASA's Cassini spacecraft has sailed seamlessly through the Nov. 21 flyby of Saturn's moon Enceladus and started transmitting uncalibrated temperature data and images of the rippling terrain. These data and images will be processed and analyzed in the coming weeks. They will help scientists create the most-detailed-yet mosaic image of the southern part of the moon's Saturn-facing hemisphere and a contiguous thermal map of one of the intriguing "tiger stripe" features, with the highest resolution to date. http://www.physorg.com/news178221538.html Space & Earth Mon, 23 Nov 2009 19:00:01 EST news178221538 (PhysOrg.com) -- When NASA's Cassini spacecraft began orbiting Saturn five years ago, a dozen highly-tuned science instruments set to work surveying, sniffing, analyzing and scrutinizing the Saturnian system. http://www.physorg.com/news177927581.html Space & Earth Fri, 20 Nov 2009 09:20:02 EST news177927581 (PhysOrg.com) -- NASA's Cassini spacecraft will fly by Saturn's moon Enceladus this weekend for a last peek at the intriguing "tiger stripes" before winter darkness blankets the area for several years. http://www.physorg.com/news177927284.html Space & Earth Fri, 20 Nov 2009 08:30:02 EST news177927284 You don't always have to have a rocket to do rocket science. Sometimes a mere airplane will do - that is, a mere Boeing 747 toting a 17-ton, 9-foot wide telescope named SOFIA. http://www.physorg.com/news177874574.html Space & Earth Thu, 19 Nov 2009 17:50:02 EST news177874574 (PhysOrg.com) -- Massive, bright clouds of tiny ice particles hover above the darkened rings of Saturn in an image captured by the Cassini spacecraft on Sept. 22, 2009, around the time of Saturn's equinox. http://www.physorg.com/news177615491.html Space & Earth Mon, 16 Nov 2009 17:40:13 EST news177615491
