    Cassini: Mission to Saturn: Cassini Beams Back First Images from New Orbit
    https://saturn.jpl.nasa.gov/news/2975/cassini-beams-back-first-images-from-new-orbit/

    NASA's Cassini spacecraft has sent to Earth its first views of Saturn’s atmosphere since beginning the latest phase of its mission.
    The new images show scenes from high above Saturn's northern hemisphere, including the planet's intriguing hexagon-shaped jet stream.

    Cassini began its new mission phase, called its Ring-Grazing Orbits, on Nov. 30. Each of these weeklong orbits - 20 in all - carries
    the spacecraft high above Saturn's northern hemisphere before sending it skimming past the outer edges of the planet's main rings.

    Cosmos on Nautilus: Extraterrestrials May Be Robots Without Consciousness
    http://cosmos.nautil.us/feature/72/it-may-not-feel-like-anything-to-be-an-alien
    Humans may have one thing that advanced aliens don’t: consciousness.

    mans are probably not the greatest intelligences in the universe. Earth is a relatively young planet and the oldest civilizations
    could be billions of years older than us. But even on Earth, Homo sapiens may not be the most intelligent species for that much longer.

    The world Go, chess, and Jeopardy champions are now all AIs. AI is projected to outmode many human professions within the next few decades.
    And given the rapid pace of its development, AI may soon advance to artificial general intelligence—intelligence that, like human intelligence,
    can combine insights from different topic areas and display flexibility and common sense. From there it is a short leap to superintelligent AI,
    which is smarter than humans in every respect, even those that now seem firmly in the human domain, such as scientific reasoning and social skills.
    Each of us alive today may be one of the last rungs on the evolutionary ladder that leads from the first living cell to synthetic intelligence.

    What we are only beginning to realize is that these two forms of superhuman intelligence—alien and artificial—may not be so distinct. The technological
    developments we are witnessing today may have all happened before, elsewhere in the universe. The transition from biological to synthetic intelligence
    may be a general pattern, instantiated over and over, throughout the cosmos. The universe’s greatest intelligences may be postbiological, having grown
    out of civilizations that were once biological. (This is a view I share with Paul Davies, Steven Dick, Martin Rees, and Seth Shostak, among others.)
    To judge from the human experience—the only example we have—the transition from biological to postbiological may take only a few hundred years.

    News | Curiosity Rover Team Examining New Drill Hiatus
    http://www.jpl.nasa.gov/news/news.php?feature=6692

    Curiosity is at a site on lower Mount Sharp selected for what would be the mission's seventh sample-collection drilling of 2016.
    The rover team learned Dec. 1 that Curiosity did not complete the commands for drilling. The rover detected a fault in an early
    step in which the "drill feed" mechanism did not extend the drill to touch the rock target with the bit.

    "We are in the process of defining a set of diagnostic tests to carefully assess the drill feed mechanism. We are using our test
    rover here on Earth to try out these tests before we run them on Mars," Curiosity Deputy Project Manager Steven Lee, at NASA's
    Jet Propulsion Laboratory in Pasadena, California, said Monday. "To be cautious, until we run the tests on Curiosity, we want to
    restrict any dynamic changes that could affect the diagnosis. That means not moving the arm and not driving, which could shake it."

    Two among the set of possible causes being assessed are that a brake on the drill feed mechanism did not disengage fully or that
    an electronic encoder for the mechanism's motor did not function as expected. Lee said that workarounds may exist for both of
    those scenarios, but the first step is to identify why the motor did not operate properly last week.

    ExoMars orbiter images Phobos / ExoMars / Space Science / Our Activities / ESA
    http://www.esa.int/Our_Activities/Space_Science/ExoMars/ExoMars_orbiter_images_Phobos

    The ExoMars Trace Gas Orbiter has imaged the martian moon Phobos as part of a second set
    of test science measurements made since it arrived at the Red Planet on 19 October.

    The Trace Gas Orbiter (TGO), a joint endeavour between ESA and Roscosmos, made its first
    scientific calibration measurements during two orbits between 20 and 28 November.

    Example data from the first orbit were published last week, focusing on Mars itself. During
    the second orbit, the instruments made a number of measurements of Phobos, a 27×22×18 km
    moon that orbits Mars at a distance of only 6000 km.

    Ocean worlds in the outer solar system - Nimmo - 2016 - Journal of Geophysical Research: Planets - Wiley Online Library
    http://onlinelibrary.wiley.com/doi/10.1002/2016JE005081/full

    Many outer solar system bodies are thought to harbor liquid water oceans beneath their ice shells. This article first reviews how such oceans are detected.
    We then discuss how they are maintained, when they formed, and what the oceans' likely characteristics are. We focus in particular on Europa, Ganymede, Callisto,
    Titan, and Enceladus, bodies for which there is direct evidence of subsurface oceans. We also consider candidate ocean worlds such as Pluto and Triton.

    SETI Reconceived and Broadened; A Call for Community Proposals | News | Astrobiology
    https://astrobiology.nasa.gov/news/seti-reconceived-and-broadened-a-call-for-community-proposals/

    Earlier this summer, Natalie Cabrol, the director of the Carl Sagan Center of the SETI Institute, described a new
    direction for her organization in Astrobiology Magazine, and I wrote a Many World column about the changes to come.

    Cabrol’s “Alien Mindscapes – Perspective on the Search for Extraterrestrial Intelligence” laid out a plan for the new approach to SETI
    that would take advantage of the goldmine of new exoplanet discoveries in the past decade, as well as the data from fast-advancing
    technologies. These fresh angles and masses of information come, she wrote, from the worlds of astronomy and astrophysics, as well as
    astrobiology and the biological, geological, environmental, cognitive, mathematical, social, and computational sciences.

    A transformation in Virgo | ESA/Hubble
    https://www.spacetelescope.org/images/potw1649a/

    Located some 60 million light-years away, NGC 4388 is experiencing some of the less desirable effects that come with
    belonging to such a massive galaxy cluster. It is undergoing a transformation, and has taken on a somewhat confused identity.

    While the galaxy’s outskirts appear smooth and featureless, a classic feature of an elliptical galaxy, its centre displays remarkable dust lanes
    constrained within two symmetric spiral arms, which emerge from the galaxy’s glowing core — one of the obvious features of a spiral galaxy.
    Within the arms, speckles of bright blue mark the locations of young stars, indicating that NGC 4388 has hosted recent bursts of star formation.

    Wow, první runda úspěšná!

    NASA's Saturn-orbiting Cassini spacecraft has made its first close dive past the outer edges of Saturn's rings
    since beginning its penultimate mission phase on Nov. 30.

    Cassini crossed through the plane of Saturn's rings on Dec. 4 at 5:09 a.m. PST (8:09 a.m. EST) at a distance
    of approximately 57,000 miles (91,000 kilometers) above Saturn's cloud tops. This is the approximate location
    of a faint, dusty ring produced by the planet’s small moons Janus and Epimetheus, and just 6,800 miles (11,000
    kilometers) from the center of Saturn's F ring.

    ALMA measures size of seeds of planets
    http://phys.org/news/2016-12-alma-size-seeds-planets.html

    Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA), have for the first time, achieved a precise size measurement
    of small dust particles around a young star through radio-wave polarization. ALMA's high sensitivity for detecting polarized radio waves
    made possible this important step in tracing the formation of planets around young stars.

    Astronomers have found a new dwarf satellite of Messier 83 (M83, also known as the Southern Pinwheel Galaxy)
    located some 85,000 light years from its host. This satellite galaxy was designated dw1335-29 and could be
    an irregular or a transition dwarf. The findings were presented in a paper published Nov. 30 on arXiv.org.
