    Galaxy's rapid growth spurt may have spawned 3000 suns per year | New Scientist
    https://www.newscientist.com/...5501-galaxys-rapid-growth-spurt-may-have-spawned-3000-suns-per-year/

    Great galaxies can grow up fast. Extreme quantities of magnesium in a quiet specimen far away reveal it was once
    one of the wildest star creators in the universe.

    The galaxy, named COSMOS 11494, is 10.7 billion light years away, so we see it when the universe was just 3.1 billion
    years old. It’s the most distant galaxy in which astronomers have measured the abundances of both magnesium and iron.

    United Nations General Assembly proclaims 30 June as International Asteroid Day
    http://www.unoosa.org/oosa/en/informationfor/media/2016-unis-os-478.html

    “The United Nations General Assembly proclaims June 30 as International Asteroid Day. We founded the annual event to raise awareness of the asteroid threat
    and opportunity to unite the human species behind a simple goal: Protect our planet from asteroid impacts. It is the only natural disaster we know how to
    prevent if we work together towards a global solution. We are all crew of Spaceship Earth.”

    Giant radio flare of Cygnus X-3 detected by astronomers
    http://phys.org/news/2016-12-giant-radio-flare-cygnus-x-.html

    Russian astronomers have recently observed a giant radio flare from a strong X-ray binary source known as Cygnus X-3
    (Cyg X-3 for short). The flare occurred after more than five years of quiescence of this source. The discovery was
    presented in a paper published Dec. 2 on the arXiv pre-print server.

    Temná hmota může být ve vesmíru rozložena rovnoměrněji | ESO Česko

    Pečlivá analýza snímků rozsáhlých oblastí oblohy pořízených dalekohledem VST přinesla překvapivý výsledek

    Analýza dat získaných v rámci rozsáhlé přehlídky galaxií, kterou v uplynulých letech prováděl dalekohled ESO/VST pracující na observatoři Paranal v Chile, naznačuje,
    že hustota temné hmoty ve vesmíru by mohla být nižší a její rozložení rovnoměrnější, než se dosud myslelo. Mezinárodní tým vědců využil snímky získané v rámci přehlídky
    KiDS (Kilo Degree Survey) k výzkumu vlivu gravitačního působení nejrozsáhlejších struktur hmoty ve vesmíru na světlo přicházející od patnácti milionů sledovaných
    vzdálených galaxií. Zdá se, že výsledky získané tímto způsobem jsou v rozporu se staršími závěry učiněnými na základě údajů z družice Planck.

    Project Starshot: Visiting the Nearest Star Within Our Lifetime

    Up Close at Alpha Centauri

    In early December the Harvard-Smithsonian Center for Astrophysics offered as part of its fall colloquium series a talk by Harvard’s Avi Loeb,
    fortunately captured on YouTube as Project Starshot: Visiting the Nearest Star Within Our Lifetime. We’ve looked at Breakthrough Starshot in
    many posts on Centauri Dreams, including my reports from the last set of meetings in Palo Alto, but for those new to the concept of using
    a laser array to send small, instrumented sails to the Alpha Centauri stars, this video is a fine introduction.

    New telescope chip offers clear view of alien planets | ANU
    http://www.anu.edu.au/news/all-news/new-telescope-chip-offers-clear-view-of-alien-planets

    Scientists have developed a new optical chip for a telescope that enables astronomers to have a clear view of alien planets that may support life.

    Seeing a planet outside the solar system which is close to its host sun, similar to Earth, is very difficult with today's standard astronomical
    instruments due to the brightness of the sun. Associate Professor Steve Madden from The Australian National University (ANU) said the new chip
    removes light from the host sun, allowing astronomers for the first time to take a clear image of the planet.

    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.

    his plan to write a historical biography, and “the world’s first working sundial tattoo.”

    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.
