    ALMA odhalila tajemství obří kosmické kaňky | ESO Česko
    http://www.eso.org/public/czechrepublic/news/eso1632/?lang

    Mezinárodnímu týmu astronomů pracujícímu s radioteleskopem ALMA a s dalšími přístroji se podařilo odhalit skutečnou povahu neobvyklého typu kosmických objektů
    ve vzdáleném vesmíru, které vědci označují jako Lyman-alpha Blob. Až dosud výzkumníci nechápali, co nutí tyto obří oblaky plynu tak intenzivně zářit. Pomocí ALMA
    se však nyní podařilo v srdci jednoho takového objektu nalézt dvojici galaxií, ve kterých překotnou rychlostí probíhá formování nových hvězd. A právě tento proces
    je zodpovědný za intenzivní vyzařování plynu v celém okolí. Dvě mohutné galaxie jsou navíc obklopeny celou skupinou menších. Zdá se tedy, že sledujeme ranou fázi
    vývoje velké galaktické kupy. Vědci předpokládají, že centrální dvojice galaxií se postupně vyvine v jednu obří eliptickou galaxii.

    Nasa scientists find 'impossible' cloud on Titan—again
    http://phys.org/news/2016-09-nasa-scientists-impossible-cloud-titanagain.html
    The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different
    process than previously thought—possibly similar to one seen over Earth's poles—could be forming clouds on Saturn's moon Titan.

    Located in Titan's stratosphere, the cloud is made of a compound of carbon and nitrogen known as dicyanoacetylene (C4N2),
    an ingredient in the chemical cocktail that colors the giant moon's hazy, brownish-orange atmosphere.

    NASA extends science operations of IRIS solar observation spacecraft - SpaceFlight Insider
    http://www.spaceflightinsider.com/...a-extends-science-operations-iris-solar-observation-spacecraft/
    NASA has decided to extend science operations of its IRIS space observatory dedicated to studying the Sun’s lower atmosphere.
    The $19.4 million extension contract awarded by the agency secures the manufacturer’s support for the mission through September
    2018 and provides additional cooperation with ground observatories worldwide.

    Quantum Mechanics Revisited: Physicists Propose New Structure of Time
    http://futurism.com/...ly-a-crystal-physicists-upend-quantum-mechanics-and-philosophy-with-new-idea/
    Physicists propose that time may not be continuous at all, but instead represent a “crystal,” a rigid structure composed of
    discrete snapshots in time. They also suggest that the smallest interval of time may be much greater than formerly supposed.

    Building an Unusual White-Dwarf Duo
    http://aasnova.org/2016/09/19/building-an-unusual-white-dwarf-duo/

    A new study has examined how the puzzling wide binary system HS 2220+2146 — which consists of two white dwarfs orbiting
    each other — might have formed. This system may be an example of a new evolutionary pathway for wide white-dwarf binaries.

    method to identify large filaments of gas and dust hiding between stars in the galactic plane.

    Quantum teleportation was just achieved over more than 7 km of city fibre - ScienceAlert
    http://www.sciencealert.com/quantum-teleportation-was-just-achieved-over-7-km-of-cable

    Quantum teleportation just moved out of the lab and into the real world, with two independent teams of scientists successfully
    sending quantum information across several kilometres of optical fibre networks in Calgary, Canada, and Hefei, China.

    The experiments show that not only is quantum teleportation very much real, it's also feasible technology that could one day
    help us build unhackable quantum communication systems that stretch across cities and maybe even continents.

    Astronomers discover five new Neptune trojans
    http://phys.org/news/2016-09-astronomers-neptune-trojans.html

    An international team of astronomers led by Hsing-Wen Lin of the National Central University in Taiwan has detected
    five new so-called "Neptune trojans" – minor bodies sharing the same orbit as the planet Neptune. The discovery was
    made by the Pan-STARRS 1 (PS1) survey and is described in a paper published Sept. 15 on arXiv.org.

    The PS1 survey, which utilizes the first Pan-STARRS (Panoramic Survey Telescope and Rapid Response System) telescope
    in Hawaii, designated PS1, is one of the best tools to search for Neptune trojans. The survey, lasting from May 2010
    to May 2014, has made a strong contribution to knowledge of the solar system's minor bodies due to its very wide
    survey area and its optimized cadence for searching moving objects.

    [1609.05089] SIOUX project: a simultaneous multiband camera for exoplanet atmospheres studies
    http://arxiv.org/abs/1609.05089

    The exoplanet revolution is well underway. The last decade has seen order-of-magnitude increases in the number
    of known planets beyond the Solar system. Detailed characterization of exoplanetary atmospheres provide the
    best means for distinguishing the makeup of their outer layers, and the only hope for understanding the interplay
    between initial composition chemistry, temperature-pressure atmospheric profiles, dynamics and circulation.

    While pioneering work on the observational side has produced the first important detections of atmospheric
    molecules for the class of transiting exoplanets, important limitations are still present due to the lack of systematic,
    repeated measurements with optimized instrumentation at both visible (VIS) and near-infrared (NIR)
    wavelengths. It is thus of fundamental importance to explore quantitatively possible avenues for improvements.
    In this paper we report initial results of a feasibility study for the prototype of a versatile multi-band imaging
    system for very high-precision differential photometry that exploits the choice of specifically selected narrow-band
    filters and novel ideas for the execution of simultaneous VIS and NIR measurements.

    Lightning on the moon? Yes, it might really happen.
    Tiny lightning bolt explosions can vaporise the moon’s thin soil | New Scientist
    https://www.newscientist.com/...423-tiny-lightning-bolt-explosions-can-vaporise-the-moons-thin-soil/

    Mini-lightning may flash in the coldest craters on the moon, melting and vapourising soil. All that sparking
    could have altered the surface as much as impacts from incoming rocks and dust. Andrew Jordan at the University
    of New Hampshire in Durham and his colleagues suggest we keep an eye out for another cause: electrical sparks.

    The lunar dust is normally an electrical insulator that can’t conduct much current. But high-energy particles
    thrown off by the sun during solar storms might be able to collect in cold patches of lunar soil.

    ‘Alien megastructure’ star may be explained by interstellar junk | New Scientist
    https://www.newscientist.com/...6335-alien-megastructure-star-may-be-explained-by-interstellar-junk/

    Step aside, alien megastructure. It seems that the behaviour of an oddity known as Tabby’s star – which some have speculated
    may be caused by a massive extraterrestrial construction project – might in reality be explained by interstellar junk.

    Now Valeri Makarov at the US Naval Observatory in Washington DC and Alexey Goldin at Teza Technologies in Chicago, Illinois, have taken a closer look
    at the smallest of the star’s dips in light – only to find that Tabby’s star isn’t responsible for them. Whenever the small dips occur, there is also
    a slight jump in the position of the light, leading them to conclude that it is actually a different star along the line of sight that is dimming.

    Tabby’s star is still responsible for the largest dips in light, however. If more than one star is dimming, say Makarov and Goldin, then the culprit
    for the erratic behaviour can’t be an asteroid belt, debris from a smash-up between two larger bodies, or an alien megastructure around Tabby’s star.
    In fact, it can’t be anything around Tabby’s star alone. Instead, it has to be something lying between us and them.
