(Phys.org) —A distant world gleaming in sunlight, Earth's twin planet, Venus, shines like a bright beacon in images taken by NASA's Cassini spacecraft in orbit around Saturn. http://phys.org/news281635546.html Space & Earth Mon, 04 Mar 2013 16:06:14 EST news281635546 (Phys.org) -- The Composite Infrared Spectrometer (CIRS) is big. It's powerful and it discovered, among other things, that Saturn's mysterious moon Enceladus was one of the very few worlds in the solar system that radiated several gigawatts of heat into space, primarily along prominent fractures dubbed "tiger stripes." http://phys.org/news263199551.html Physics Fri, 03 Aug 2012 08:10:01 EST news263199551 (Phys.org) -- Recent findings from NASA's Cassini mission reveal that Saturn's geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some Cassini scientists think they have observed "dusty plasma," a condition theorized but not previously observed on site, near Enceladus. http://phys.org/news257696769.html Space & Earth Thu, 31 May 2012 15:26:15 EST news257696769 Microbes living at the edges of Arctic ice sheets could help researchers pinpoint evidence for similar microorganisms that could have evolved on Mars, the Jovian moon Europa, or Saturn's moon Enceladus. http://phys.org/news256463410.html Space & Earth Thu, 17 May 2012 08:50:26 EST news256463410 On May 2, the Cassini spacecraft will be swooping past the moon we all love to love — Enceladus — and coming within 74 kilometers (46 miles) of its fractured, jet-spewing surface. http://phys.org/news255165563.html Space & Earth Wed, 02 May 2012 08:50:01 EST news255165563 (Phys.org) -- Less than three weeks after its last visit to the Saturnian moon Enceladus, NASA's Cassini spacecraft returns for an encore. At closest approach on April 14, the spacecraft will be just as low over the moon's south polar region as it was on March 27 -- 46 miles, or 74 kilometers. http://phys.org/news253783629.html Space & Earth Mon, 16 Apr 2012 08:27:16 EST news253783629 (PhysOrg.com) -- NASA's Cassini spacecraft is preparing to make its lowest pass yet over the south polar region of Saturn's moon Enceladus, where icy particles and water vapor spray out in glittering jets. The closest approach, at an altitude of about 46 miles (74 kilometers), will occur around 11:30 a.m. PDT (2:30 p.m. EDT) on March 27. http://phys.org/news252056486.html Space & Earth Tue, 27 Mar 2012 09:00:02 EST news252056486 (PhysOrg.com) -- Images from NASA's Cassini spacecraft have, for the first time, enabled scientists to correlate the spraying of jets of water vapor from fissures on Saturn's moon Enceladus with the way Saturn's gravity stretches and stresses the fissures. The result is among the Cassini findings presented today at the Lunar and Planetary Science Conference at The Woodlands, Texas. http://phys.org/news251450460.html Space & Earth Tue, 20 Mar 2012 08:21:09 EST news251450460 After more than two decades of drilling in Antarctica, Russian scientists have reached a gigantic freshwater lake hidden under miles of ice for some 20 million years - a pristine body of water that may hold life from the distant past and clues to the search for life on other planets. http://phys.org/news247937551.html Space & Earth Wed, 08 Feb 2012 15:32:40 EST news247937551 Scientists have been puzzled by periodic bursts of radiation, known as the Saturn kilometric radiation (SKR), that occur in the planet's magnetosphere. These emissions occur at a rate that is close to, but not quite the same as, the rate at which the planet rotates. http://phys.org/news244531799.html Space & Earth Sat, 31 Dec 2011 05:30:06 EST news244531799 The moon Enceladus, one of the jewels of the Saturn system, sparkles peculiarly bright in new images obtained by NASA's Cassini spacecraft. The images of the moon, the first ever taken of Enceladus with Cassini's synthetic aperture radar, reveal new details of some of the grooves in the moon's south polar region and unexpected textures in the ice. These images, obtained on Nov. 6, 2011, are the highest-resolution images of this region obtained so far. http://phys.org/news242036964.html Space & Earth Fri, 02 Dec 2011 09:20:01 EST news242036964 (PhysOrg.com) -- This false-color mosaic from NASA's Cassini spacecraft shows the tail of Saturn's huge northern storm. In mid-September 2004, the Cassini spacecraft chronicled a similar, but smaller, storm in the southern hemisphere called the "Dragon Storm." http://phys.org/news241081659.html Space & Earth Mon, 21 Nov 2011 07:07:51 EST news241081659 (PhysOrg.com) -- Saturn's moon Enceladus shows its icy face and famous plumes in raw, unprocessed images captured by NASA's Cassini spacecraft during its successful flyby on Nov. 6, 2011. http://phys.org/news239951453.html Space & Earth Tue, 08 Nov 2011 05:11:02 EST news239951453 (PhysOrg.com) -- Raw, unprocessed images from the successful Oct. 19 flyby of Saturn's moon Enceladus by NASA's Cassini spacecraft provide new views of the moon and the icy jets that burst from its southern polar region. http://phys.org/news238398278.html Space & Earth Fri, 21 Oct 2011 06:44:58 EST news238398278 (PhysOrg.com) -- NASA's Cassini mission will take advantage of the position of two of the three stars in Orion's belt when the spacecraft flies by Saturn's moon Enceladus on Wed., Oct. 19. As the hot, bright stars pass behind the moon's icy jets, Cassini's ultraviolet imaging spectrograph will acquire a two-dimensional view of these dramatic plumes of water vapor and icy material erupting from the moon's southern polar region. This flyby is the mission's first-ever opportunity to probe the jets with two stars simultaneously, a dual stellar occultation. http://phys.org/news238233392.html Space & Earth Wed, 19 Oct 2011 08:56:51 EST news238233392 (PhysOrg.com) -- NASA's Cassini spacecraft successfully completed its Oct. 1 flyby of Saturn's moon Enceladus and its jets of water vapor and ice. At its closest approach, the spacecraft flew approximately 62 miles (100 kilometers) above the moon's surface. The close approach was designed to give some of Cassini's instruments, including the ion and neutral mass spectrometer, the chance to "taste" the jets themselves. http://phys.org/news236932777.html Space & Earth Tue, 04 Oct 2011 07:50:01 EST news236932777 (PhysOrg.com) -- ESA's Herschel space observatory has shown that water expelled from the moon Enceladus forms a giant torus of water vapour around Saturn. The discovery solves a 14-year mystery by identifying the source of the water in Saturn’s upper atmosphere. http://phys.org/news230891391.html Space & Earth Tue, 26 Jul 2011 09:30:04 EST news230891391 (PhysOrg.com) -- Data from NASA's Cassini spacecraft have revealed that Enceladus, one of Saturn's diminutive moons, is linked to Saturn by powerful electrical currents - beams of electrons that flow back and forth between the planet and moon. The finding is part of a paper published in Nature today. http://phys.org/news222523646.html Space & Earth Wed, 20 Apr 2011 13:07:47 EST news222523646 (PhysOrg.com) -- Heat output from the south polar region of Saturn's moon Enceladus is much greater than was previously thought possible, according to a new analysis of data collected by NASA's Cassini spacecraft. The study was published in the Journal of Geophysical Research on March 4. http://phys.org/news218790998.html Space & Earth Tue, 08 Mar 2011 07:17:21 EST news218790998 (PhysOrg.com) -- Saturn's icy moon Rhea might seem a strange place to look for clues to understanding the vast majestic rings encircling Saturn. But that's what NASA's Cassini spacecraft plans to do on its next flyby of Rhea. At closest approach, Cassini will pass within about 69 kilometers (43 miles) of the surface at 4:53 AM UTC on Tuesday, Jan. 11, which is 10:53 PM Pacific Time on Monday, Jan. 10. This flyby is the closest Cassini will get to the icy moon's surface. http://phys.org/news213957777.html Space & Earth Tue, 11 Jan 2011 09:10:01 EST news213957777 On the heels of a successful close flyby of Saturn's moon Enceladus, NASA's Cassini spacecraft is returning images of Enceladus and the nearby moon Dione. http://phys.org/news212230777.html Space & Earth Wed, 22 Dec 2010 08:59:51 EST news212230777 (PhysOrg.com) -- NASA's Cassini spacecraft successfully dipped near the surface of Saturn's moon Enceladus on Nov. 30. http://phys.org/news210510490.html Space & Earth Thu, 02 Dec 2010 11:08:22 EST news210510490 (PhysOrg.com) -- NASA's Cassini spacecraft resumed normal operations today, Nov. 24.
