Saturn: Tethys ‘Eyes’ Saturn The two large craters on Tethys, near the line where day fades to night, almost resemble two giant eyes observing Saturn. [edit] Margins blown. Please see NASA for the image. The location of these craters on Tethys’ terminator throws their topography into sharp relief. Both are large craters, but the larger and southernmost of the two shows a more complex structure. The angle of the lighting highlights a central peak in this crater. Central peaks are the result of the surface reacting to the violent post-impact excavation of the crater. The northern crater does not show a similar feature. Possibly the impact was too small to form a central peak, or the composition of the material in the immediate vicinity couldn’t support the formation of a central peak. http://www.nasa.gov/jpl/cassini/pia18318/tethys-eyes-saturn |

Thank's Lynn for the updates . while checking out the photo's i thought that is weird , The north pole , I'm not liking the explanation of the Hexagon a jet stream ? I would have thought it would be a circle not a Hexagon . Has this been seen anywhere else , Jupiter or even our own planet ? |

Thanks Klik , I thought they where just making it up But from those experiments there not . The universe is very weird that's foe shore and Fantastic . |

It's an approximation of a hexagon to us on earth. What has caused that we simply don't know. Aliens, of course. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

press-release All Systems Go for NASA's Mission to Jupiter Moon Europa Beyond Earth, Jupiter’s moon Europa is considered one of the most promising places in the solar system to search for signs of present-day life, and a new NASA mission to explore this potential is moving forward from concept review to development. NASA’s mission concept -- to conduct a detailed survey of Europa and investigate its habitability -- has successfully completed its first major review by the agency and now is entering the development phase known as formulation. “Today we’re taking an exciting step from concept to mission, in our quest to find signs of life beyond Earth,†said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington. “Observations of Europa have provided us with tantalizing clues over the last two decades, and the time has come to seek answers to one of humanity’s most profound questions.†https://youtu.be/GqTaDCt_F1Y NASA Video http://www.nasa.gov/press-release/all-systems-go-for-nasas-mission-to-jupiter-moon-europa |

I noticed it's not calling for a lander and it won't even orbit Europa. All data to be collected during fly bys as it orbits Jupiter. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Dione Moon. Cassini's Final Breathtaking Close Views of Dione A pockmarked, icy landscape looms beneath NASA's Cassini spacecraft in new images of Saturn's moon Dione taken during the mission's last close approach to the small, icy world. Two of the new images show the surface of Dione at the best resolution ever. Cassini passed 295 miles (474 kilometers) above Dione's surface at 11:33 a.m. PDT (2:33 p.m. EDT) on Aug. 17. This was the fifth close encounter with Dione during Cassini's long tour at Saturn. The mission's closest-ever flyby of Dione was in Dec. 2011, at a distance of 60 miles (100 kilometers). http://www.nasa.gov/feature/cassinis-final-breathtaking-close-views-of-dione |

did anybody notice the boinc logo on the left side right below the equator? I came down with a bad case of i don't give a crap |

Cassini Saturn. At Saturn, One of These Rings is not like the Others When the sun set on Saturn's rings in August 2009, scientists on NASA's Cassini mission were watching closely. It was the equinox -- one of two times in the Saturnian year when the sun illuminates the planet's enormous ring system edge-on. The event provided an extraordinary opportunity for the orbiting Cassini spacecraft to observe short-lived changes in the rings that reveal details about their nature. Like Earth, Saturn is tilted on its axis. Over the course of its 29-year-long orbit, the sun's rays move from north to south over the planet and its rings, and back again. The changing sunlight causes the temperature of the rings -- which are made of trillions of icy particles -- to vary from season to season. During equinox, which lasted only a few days, unusual shadows and wavy structures appeared and, as they sat in twilight for this brief period, the rings began to cool. http://www.nasa.gov/feature/jpl/at-saturn-one-of-these-rings-is-not-like-the-others |

Saturn's Moon Enceladus Cassini Finds Global Ocean in Saturn's Moon Enceladus A global ocean lies beneath the icy crust of Saturn's geologically active moon Enceladus, according to new research using data from NASA's Cassini mission. Researchers found the magnitude of the moon's very slight wobble, as it orbits Saturn, can only be accounted for if its outer ice shell is not frozen solid to its interior, meaning a global ocean must be present. The finding implies the fine spray of water vapor, icy particles and simple organic molecules Cassini has observed coming from fractures near the moon's south pole is being fed by this vast liquid water reservoir. The research is presented in a paper published online this week in the journal Icarus. http://www.nasa.gov/press-release/cassini-finds-global-ocean-in-saturns-moon-enceladus |

Back before Cassini astronomers predicted that Saturn's rings are transient in nature and would eventually dissipate. I presume now that given the new evidence the rings will continue probably until the sun burns out. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Jupiter’s Great Red Spot. Hubble’s Planetary Portrait Captures New Changes in Jupiter’s Great Red Spot https://youtu.be/3afEX8a2jPg You Tube Scientists using NASA’s Hubble Space Telescope have produced new maps of Jupiter – the first in a series of annual portraits of the solar system’s outer planets. Collecting these yearly images – essentially the planetary version of annual school picture days for children – will help current and future scientists see how these giant worlds change over time. The observations are designed to capture a broad range of features, including winds, clouds, storms and atmospheric chemistry. Already, the Jupiter images have revealed a rare wave just north of the planet’s equator and a unique filamentary feature in the core of the Great Red Spot not seen previously. http://www.nasa.gov/press-release/goddard/hubble-s-planetary-portrait-captures-new-changes-in-jupiter-s-great-red-spot |

Gored Clump in Saturn's F Ring Saturn's dynamic F ring contains many different types of features to keep scientists perplexed. In this image we see features ring scientists call "gores," to the right of the bright clump, and a "jet," to the left of the bright spot. Thanks to the ring's interaction with the moons Prometheus and Pandora, and perhaps a host of smaller moonlets hidden in its core, the F ring is a constantly changing structure, with features that form, fade and re-appear on timescales of hours to days. This view looks toward the unilluminated side of the rings from about 7 degrees below the ring plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 15, 2015. The view was acquired at a distance of approximately 295,000 miles (475,000 kilometers) from Saturn and at a Sun-ring-spacecraft, or phase, angle of 117 degrees. Image scale is 1.8 miles (2.9 kilometers) per pixel. http://www.nasa.gov/image-feature/jpl/cassini/pia18337/gored-clump-in-saturns-f-ring |

Cassini just passed 49 km above Enceladus South pole across its plumes to determine their composition. Tullio |
