How Charged Water Particles Affect Saturn's Atmosphere
2013-04-10 19:36:15

Lee Rannals for redOrbit.com — Your Universe Online A new study published in the journal Nature found that the "rain" of charged water particles in Saturn's atmosphere influences the composition and temperature of the planet's upper atmosphere and rings. The study, led by the University of Leicester in England, reveals that there is a significant interaction between its atmosphere and ring system. "The main effect of ring rain is that it acts to 'quench' the ionosphere of...

Saturn’s Moon Telesto Discovered 33 Years Ago Today
2013-04-08 18:47:23

Lee Rannals for redOrbit.com — Your Universe Online Thirty-three years ago today, astronomers discovered Saturn's moon Telesto using ground-based observations. Astronomers Bradford A. Smith, Harold Reitsema, Stephen M. Larson and John W. Fountain were performing ground observations on April 8, 1980 when they discovered the Saturn moon. The moon was officially named after Telesto of Greek mythology, but was also designated as Saturn XIII or Tethys B. NASA said Telesto is known...

Cassini Shows Saturn As An Antique Shop
2013-03-27 18:43:08

Lee Rannals for redOrbit.com — Your Universe Online NASA's Cassini spacecraft has unveiled new data about how Saturn's moons and rings are like an antique shop. Gianrico Filacchione, a Cassini participating scientist at Italy's National Institute for Astrophysics, Rome, published a paper online in The Astrophysical Journal about how Saturn's moons and rings are gently worn, vintage goods from around the time of our solar system's birth. He suggests these bodies date back more...

Smithsonian Honors Team Behind Successful Mars Curiosity Landing

Brett Smith for redOrbit.com - Your Universe Online The Smithsonian National Air and Space Museum announced that the team responsible for the successful landing of NASA´s Mars Curiosity rover will receive its 2013 Trophy for Current Achievement on April 24 in Washington DC. “The Current Achievement winner can be summarized in two words: sky crane,” said a museum press release describing the award. “This phrase embodied the audacious plan that the Entry, Descent,...

Last Close Flyby Of Saturnian Moon Rhea Made By Cassini
2013-03-08 08:57:45

NASA NASA's Cassini spacecraft will be swooping close to Saturn's moon Rhea on Saturday, March 9, the last close flyby of Rhea in Cassini's mission. The primary purpose will be to probe the internal structure of the moon by measuring the gravitational pull of Rhea against the spacecraft's steady radio link to NASA's Deep Space Network here on Earth. The results will help scientists understand whether the moon is homogeneous all the way through or whether it has differentiated into the...

Cassini Spies On Earth's Sister Venus From Behind Saturn's Rings
2013-03-04 13:54:02

Lee Rannals for redOrbit.com — Your Universe Online The international Cassini spacecraft, a NASA, European Space Agency (ESA) and Italian Space Agency (ASI) jointly-operated project, has taken some unique pictures of Earth's twin planet from the perspective of Saturn. The Cassini-Huygens mission launched on October 15, 1997, traveling 2.2 billion miles toward Saturn, reaching the distant ringed-planet June 30, 2004. The orbiter includes 18 sophisticated science instruments to help...

Cassini Catches Solar Wind, Helps NASA Study Particle Acceleration
2013-02-20 14:23:12

Michael Harper for redOrbit.com — Your Universe Online As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies. Particles which are accelerated this much are usually found surrounding far away supernovas. This is good news for...

Cassini Records Possible Supernova Shockwave On Saturn
2013-02-18 16:08:11

Lee Rannals for redOrbit.com - Your Universe Online For the first time, scientists from the international Cassini spacecraft have detected subatomic particles that have been accelerated to ultra-high energies in a blast of solar wind around Saturn, hinting at the possibility that the ringed planet may have experienced the aftermath of a supernova. According to a report by the European Space Agency (ESA) that appeared recently in the journal Nature Physics, this acceleration may be the...

Smog Detected At Northern Hemisphere Of Saturn Moon Titan
2013-02-05 08:33:50

April Flowers for redOrbit.com - Your Universe Online An international group of scientists, led by Panayotis Lavvas of the University of Reims, Champagne-Ardenne, used data from NASA's Cassini mission to describe, in unparalleled detail, how aerosols in the highest part of the atmosphere are kick-started on Saturn's moon Titan. The study, published in a recent issue of Proceedings of the National Academy of Sciences (PNAS), seeks to understand aerosol formation at Titan because it could...

Six Month Saturn Storm Eats Itself
2013-01-31 19:48:37

Lee Rannals for redOrbit.com — Your Universe Online Cassini mission scientists have observed a huge thunder-and-lightning storm on Saturn consume itself for the first time. The NASA scientists said in a paper published in the journal Icarus that they observed as the massive storm made its way around the planet, until it ran into its own tail and dissipated. "This Saturn storm behaved like a terrestrial hurricane - but with a twist unique to Saturn," Andrew Ingersoll, a Cassini...

Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...

The Planet Saturn -- in astronomy, 6th planet from the sun. Astronomical and Physical Characteristics of Saturn Saturn's orbit lies between those of Jupiter and Uranus; its mean distance from the sun is c.886 million mi (1.43 billion km), almost twice that of Jupiter, and its period of revolution is about 291/2 years. Saturn appears in the sky as a yellow, starlike object of the first magnitude. When viewed through a telescope, it is seen as a golden sphere, crossed by a series of...
