    Hubble rounds up the first worlds we’ll check for alien life | New Scientist
    https://www.newscientist.com/...2113843-hubble-rounds-up-the-first-worlds-well-check-for-alien-life/

    The search for alien life is taking a shortcut. The Hubble Space Telescope is set to spend hundreds of hours
    over the next year running reconnaissance on a shortlist of worlds to identify those we should scour for life first.

    This latest effort aims to take advantage of Hubble’s successor, the James Webb Space Telescope. Set to launch in 2018,
    JWST will have unprecedented power to detect the atmospheres of faraway planets for biosignature gases that would suggest
    they host living, breathing organisms.

    Did comets kick-start life on Earth? (video) | EurekAlert! Science News
    https://www.eurekalert.org/pub_releases/2016-11/acs-dck112316.php

    The origins of life on Earth are still shrouded in mystery. One compelling possibility is
    that comets delivered the building blocks for life eons ago. This week, Speaking of Chemistry
    explains the chemistry behind how these icy, lumpy space rocks might have seeded life on Earth.

    Úžasné výsledky Sentinelů..

    Satellites confirm sinking of San Francisco tower / Sentinel-1 / Copernicus / Observing the Earth / Our Activities / ESA
    http://www.esa.int/..._Earth/Copernicus/Sentinel-1/Satellites_confirm_sinking_of_San_Francisco_tower
    The Sentinel-1 satellites have shown that the Millennium Tower skyscraper in the centre of San Francisco is sinking by a few centimetres a year.
    Studying the city is helping scientists to improve the monitoring of urban ground movements, particularly for subsidence hotspots in Europe.

    Completed in 2009, the 58-storey Millennium Tower has recently been showing signs of sinking and tilting. Although the cause has not been
    pinpointed, it is believed that the movements are connected to the supporting piles not firmly resting on bedrock.

    A new study says that the dinosaur-killing asteroid not only killed the breed but also punched a hole in Earth's crust
    that remains visible until today. Reports say that a six-mile wide asteroid that impacted the Earth about 65 million
    years ago created an 18-mile deep hole in the Earth's crust. This mark still bore evidence of the impact until today.

    X-Ray Background from Early Binaries
    http://aasnova.org/2016/11/23/x-ray-background-from-early-binaries/

    What impact did X-rays from the first binary star systems have on the universe around them?
    A new study suggests this radiation may have played an important role during the reionization of our universe.

    Is the universe a sponge? - physicsworld.com
    http://physicsworld.com/cws/article/indepth/2016/nov/24/is-the-universe-a-sponge

    Does the large-scale universe look more like meatballs, like Swiss cheese or like a sponge? A meatball universe would be composed of isolated,
    disconnected regions of high density embedded in a connected low-density background. The Swiss cheese universe would be precisely the opposite:
    low-density isolated voids embedded in a high-density connected background. A sponge is neither of the above or, if you prefer, a compromise
    between the two. In a sponge both the low-density and high-density regions are each connected, and ideally both the sponge and its “complement”
    (the network of holes) are identical in character, at least from a topological point of view.

    Shear brilliance: Computing tackles the mystery of the dark universe
    http://phys.org/news/2016-11-brilliance-tackles-mystery-dark-universe.html

    Scientists from The University of Manchester working on a revolutionary telescope project have harnessed the power of distributed computing
    from the UK's GridPP collaboration to tackle one of the Universe's biggest mysteries – the nature of dark matter and dark energy.

    Researchers at The University of Manchester have used resources provided by GridPP – who represent the UK's contribution to the computing grid
    used to find the Higgs boson at CERN – to run image processing and machine learning algorithms on thousands of images of galaxies from
    the international Dark Energy Survey.

    The Manchester team are part of the collaborative project to build the Large Synoptic Survey Telescope (LSST), a new kind of telescope currently
    under construction in Chile and designed to conduct a 10-year survey of the dynamic Universe. LSST will be able to map the entire visible sky.

    N4RC0T1C: Zdravím, díky moc. :)

    K odstavci 1: je to možné, koneckonců naše civilizace také využívá fyzikálních zákonů,
    viz třeba gravitační manévry sond v blízkosti planet (taková mládežnická verze
    benefitů díky gravitaci hmotných těles). Otázkou je, jak by se daná civilizace
    vypořádala s turbulentním prostředím, zářením, teplotama...
    Ale podstatné je, že žádné fyz. zákony využití dilatace nezakazují.

    U odstavce 2 je už vše "vachrlatější", protože jde o čiré dohady, navíc týkající se i ""psychologie""
    dané civilizace. A tady bohužel neznáme nic jiného, než tu naši, a ta nás přesvědčuje o opaku.
    Navíc "vyčůraně čekat" se nemusí vyplácet, protože dřív než shrábneme technol. vychytávky, můžeme
    schytat nějakou hodně nepříjemnou událost (výbuch blízké supernovy, asteroid, kolize těles
    u vícečetných hvězdných/planetárních systémů atp...)

    Jenže při těchto úvahách zase vycházíme jen a jen z našich zkušeností, což nemusí být směrodatné.

    štítu nastal problém s gyroskopem. Palubní počítač zpracoval jeho výstup tak, že sonda je už na povrchu..
