    No slušně takhle při pátku!! (a teď už víkendu)

    Scientists to unveil new Earth-like planet: report
    http://phys.org/news/2016-08-scientists-unveil-earth-like-planet.html

    Scientists are preparing to unveil a new planet in our galactic neighbourhood which is "believed to be Earth-like"
    and orbits its star at a distance that could favour life, German weekly Der Spiegel reported Friday.
    The exoplanet orbits a well-investigated star called Proxima Centauri, part of the Alpha Centauri star system,
    the magazine said, quoting anonymous sources.
    "The still nameless planet is believed to be Earth-like and orbits at a distance to Proxima Centauri that could
    allow it to have liquid water on its surface—an important requirement for the emergence of life," said the magazine.
    "Never before have scientists discovered a second Earth that is so close by," it said, adding that the European
    Southern Observatory (ESO) will announce the finding at the end of August.

    The report gave no further details.

    News | Cassini Finds Flooded Canyons on Titan
    http://www.jpl.nasa.gov/news/news.php?release=2016-207

    NASA's Cassini spacecraft has found deep, steep-sided canyons on Saturn's moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well as the first observation of canyons hundreds of meters deep.

    A new paper in the journal Geophysical Research Letters describes how scientists analyzed Cassini data from a close pass the spacecraft made over Titan in May 2013. During the flyby, Cassini's radar instrument focused on channels that branch out from the large, northern sea Ligeia Mare.

    Through exploration, NASA is broadening horizons, enhancing knowledge, and improving our way of life. Our efforts to explore and discover the universe
    are increasing in both scope and duration. The Space Launch System (SLS), the most powerful rocket in the world, soon will launch the Orion spacecraft
    and its crew deeper into space than ever before. Expanding humanity’s presence farther into the solar system also requires advancements in
    the development of habitats and the systems to keep astronauts safe as they live and work in deep space for long periods of time.

    Rozlišení Hubbleova dalekohledu je mezi 0,05-0,1 úhlové sekundy (podle přístroje a vlnové délky). Nejmodernější pozemní adaptivní optika funguje (s expoziční dobou o dost delší než u HST) dnes tak do 0,02 úhlové sekundy ve viditelném oboru. KIC 8462852 je od nás cca 450 parseků (1500 světelných let). Protože 1 parsek je určen tak, že z té vzdálenosti má úsečka o délce 1 astronomická jednotka zdánlivý rozměr 1 úhlová sekunda, je limit prostorového rozlišení ve viditelném oboru u HST pro KIC 8462852 cca 20-45 AU, pro nejlepší pozemskou adaptivní optiku cca 10 AU. To na rozměry "stíničů" (cca 0,001-0,01 AU, zřejmé z průběhů jasu a rozměrů hvězdy) nestačí ani omylem.
    V optické oblasti v rozlišení zatím pokud vím vede (pro dost jasné objekty) pokud vím VLTI interferometr na Evropské Jižní Observatoři. Při jeho cca 0,001 úhlové sekundě rozlišení to pro KIC 8462852 dává fyzické rozměry cca 0,5 AU. Sexy, ale pořád málo.
    Pro "superinterferometr" VLBA (základna=Země) v rádiovém oboru je pro vlnovou délku 3 mm limit cca 0,0001 úhlové sekundy, to by už bylo "jen" cca 10x nedostatečné, ale KIC 8462852 je v rádiových oborech zdá se celkem normální.
    Není zač.

    Most volcanic activity on Mercury stopped about 3.5 billion years ago – Astronomy Now
    http://astronomynow.com/...07/most-volcanic-activity-on-mercury-stopped-about-3-5-billion-years-ago/
    New research from North Carolina State University finds that major volcanic activity on the planet Mercury
    most likely ended about 3.5 billion years ago. These findings add insight into the geological evolution of
    Mercury in particular, and what happens when rocky planets cool and contract in general.
