    NEBULA: Noooo! :)

    To bude moc zajímavý, a pokud půjde o další (lepší) potvrzení výtrysků, bude to fajn.
    Ale možná půjde o definitivní povrzení oceánu pod silnou krustou. Napovídala by tomu
    celá "slavnostní" aranž tohoto telkonu...

    Mark Zuckerberg, Yuri Milner and Stephen Hawking to begin search for alien life | Daily Mail Online
    http://www.dailymail.co.uk/...king-begin-100-million-search-alien-life-nearby-Earth-like-planet.html

    Facebook CEO Mark Zuckerberg, Russian entrepreneur Yuri Milner and physicist Stephen Hawking have revealed exclusively to MailOnline that they will be listening to signals
    from 'Earth 2.0'. Officially named Proxima b, the rocky planet is believed to have the right conditions to harbour life and is just four light years from Earth. The trio are
    funding an ambitious $100 million (£76 million) project known as ‘Breakthrough Listen’, which will use the world's most powerful telescopes to listen to messages from ET.

    A Strange New Theory of How Space-Time is Emerging | Physics-Astronomy
    http://www.physics-astronomy.com/2014/09/a-strange-new-theory-of-how-space-time.html#.V-Vy0fl95hE

    "A metaphorical chip holding all the programming for our universe stores information like a quantum computer." This is the radical insight
    to the foundation of our Universe developed by Mark Van Raamsdonk, a professor of theoretical physics at the University of British Columbia,
    that says that the world we see around us is a projection from a set of rules written in simpler, lower-dimensional physics—just as the 2D
    code in a computer’s memory chip creates an entire virtual 3D world. "What Mark has done is put his finger on a key ingredient of how space-
    time is emerging: entanglement," says Gary Horowitz, who studies quantum gravity at the University of California Santa Barbara. Horowitz says
    this idea has changed how people think about quantum gravity, though it hasn’t yet been universally accepted. "You don’t come across this
    idea by following other ideas. It requires a strange insight," Horowitz adds. "He is one of the stars of the younger generation."

    Curiosity Rover drives away from the drill site at Quela

    Drive date Sol 1468 (September 22, 2016). Point-to-Point drive distance was 87.38 meters (286.69 feet),
    with a climb of ~4.2 meters (~13.78 feet), drive duration was ~136 minutes, drive direction was ~South
    Southeast (148º). Attached is a crop from the official JPL location map with a few added annotation to
    clarify selected details. A link to the full size map is included at the end of this post.

    World's tectonic plate movement mapped | Geology Page
    http://www.geologypage.com/2014/08/worlds-tectonic-plate-movement-mapped.html
    A group of geophysicists is testing the hypothesis that the rate of “supercontinent assembly” — or tectonic plate movement—changes over time.
    Study co-author Professor Sergei Pisarevskiy says plate tectonics is the study of the horizontal movement of tectonic plates over the Earth’s surface.
    “This is not uniform movement,” he says.

    New Research Suggest Andromeda And Milky Way Galaxies Are Already Touching, Might Collide Sooner Than We Think
    http://sci-techuniverse.blogspot.com/2016/06/new-research-suggest-andromeda-and.html

    The Milky Way and Andromeda galaxy won’t collide for next 4 billion years. But a recent discovery of a massive halo of hot gas close to Andromeda Galaxy
    may mean that our galaxies are already touching. Astrophysicist Nicholas Lehner from University of Notre Dame, led a group of scientists using the Hubble
    Space Telescope to detect an enormous halo of hot, ionized gas about 2 million light years in diameter around the galaxy.

    Incoming! New Warning System Tracks Potentially Dangerous Asteroids
    http://www.space.com/34149-asteroid-impact-warning-system-scout.html

    A new early warning system may help speed up calculations of when and where incoming asteroids could strike Earth.

    By monitoring observations of newly reported space objects, a computer program called Scout can quickly identify potentially
    dangerous asteroids, then automatically call for follow-ups to calculate a more precise path for these bodies, researchers said.

    "These are objects that observers have reported, and they suspect them to be asteroids," Paul Chodas, manager of NASA's Center
    for Near-Earth Object (NEO) Studies at the Jet Propulsion Laboratory (JPL) in California, told Space.com. "They are most likely
    asteroids, but they need to be confirmed by other observers.

    In exploring the ‘now,’ new book links flow of time with Big Bang | Berkeley News
    http://news.berkeley.edu/2016/09/20/new-book-links-flow-of-time-with-big-bang/

    Muller’s new idea: Time is expanding because space is expanding.

    “The new physics principle is that space and time are linked;
    when you create new space, you will create new time,” Muller said.

    “Every moment, the universe gets a little bigger, and there is a little more time, and it is this leading edge of time
    that we refer to as now,” he writes. “The future does not yet exist … it is being created. Now is at the boundary,
    the shock front, the new time that is coming from nothing, the leading edge of time.”

    Muller’s theory explaining the flow of time led to a collaboration with Caltech theoretician Shaun Maguire and a paper
    posted online June 25 that explains the theory in more detail – using mathematics – and proposes a way to test it using
    LIGO, an experiment that detects gravitational waves created by merging black holes.

    If Muller and Maguire are right, then when two black holes merge and create new space, they should also create new time,
    which would delay the gravitational wave signal LIGO observes from Earth.

    “The coalescing of two black holes creates millions of cubic miles of new space, which means a one-time creation of new time,”
    Muller said. The black hole merger first reported by LIGO in February 2016 involved two black holes weighing about 29 and 36
    times the mass of the sun, producing a final black hole weighing about 62 solar masses. The new space created in the merger
    would produce about 1 millisecond of new time, which is near the detection level of LIGO. A similar event at one-third
    the distance would allow LIGO to detect the newly created time.

    http://sci-techuniverse.blogspot.com/2016/04/an-earth-like-planet-only-16-light.html

    Earth may have a new neighbor, in the form of an Earth-like planet in a solar system only 16 light years away. The planet orbits a star named Gliese 832,
    and that solar system already hosts two other known exoplanets: Gliese 832B and Gliese 832C. The findings were reported in a new paper by Suman Satyal at
    the University of Texas, and colleagues J. Gri?th, and Z. E. Musielak.

    Gliese 832B is a gas giant similar to Jupiter, at 0.64 the mass of Jupiter, and it orbits its star at 3.5 AU. G832B probably plays a role similar to Jupiter
    in our Solar System, by setting gravitational equilibrium. Gliese 832C is a Super-Earth about 5 times as massive as Earth, and it orbits the star at a very
    close 0.16 AU. G832C is a rocky planet on the inner edge of the habitable zone, but is likely too close to its star for habitability. Gliese 832, the star
    at the center of it all, is a red dwarf about half the size of our Sun, in both mass and radius.

    Juno and Marble Movie update at Apojove 1 | The Planetary Society
    http://www.planetary.org/blogs/emily-lakdawalla/2016/09221047-juno-and-marble-movie-update.html
    Juno se při svém druhém oběhu dostal ve středu do apojovu (nejdál od planety), a vrací se zpět k joviánskému severnímu pólu,
    nad kterým proletí 19. října. V té době dojde k opětovnému zážehu, který změní jeho oběžnou dobu ze současných 55,5 dní na
    dva týdny. Sonda je v dobrém stavu, a je připravena na listopadový počátek vědeckého výzkumu.

    V pondělí 26/09 se Slunce dostane do dráhy Země-Jupiter, proto je od dnešního dne na týden pozastavena komunikace se sondou.
    To bude znamenat i pozastavení záznamu Junocamu, který nepřetržitě snímkuje polohy planety a galileovských měsíců už od 11.
    července. Záznam znovu začne 30.9. a skončí 18.10. Gerald Eichstädt editoval tříminutovou poslední veri, kterou Emily
    uveřejnila na Planetary v rámci tohoto krátkého reportu.
