    News | Test for Damp Ground at Mars' Seasonal Streaks Finds None
    http://www.jpl.nasa.gov/news/news.php?release=2016-215&rn=news.xml&rst=6597
    Seasonal dark streaks on Mars that have become one of the hottest topics in interplanetary research don't hold much water,
    according to the latest findings from a NASA spacecraft orbiting Mars.

    The new results from NASA's Mars Odyssey mission rely on ground temperature, measured by infrared imaging using the spacecraft's Thermal Emission Imaging System (THEMIS).
    They do not contradict last year's identification of hydrated salt at these flows, which since their 2011 discovery have been regarded as possible markers for the presence
    of liquid water on modern Mars. However, the temperature measurements now identify an upper limit on how much water is present at these darkened streaks: about as much as
    in the driest desert sands on Earth.

    How the magnetic fields of galaxies may have been formed
    http://3tags.org/article/how-the-magnetic-fields-of-galaxies-may-have-been-formed
    Scientists are using powerful lasers to mimic the effects of supernovae, which are helping to reveal how the magnetic fields of galaxies may have been formed in the
    early universe. All galaxies have magnetic fields, ones that might affect how fast stars are born, but it hasn’t been discovered where these magnetic fields come from.

    The standard model explains that these fields form from tiny magnetic fields, which existed before galaxies appeared, serving as cosmic seeds that were amplified over
    billions of years by the turbulence in the intergalactic medium. It’s still unclear how these seeding magnetic fields initially arose.

    VIRGO: mno, na Europě (a možná i na Ganymedu - o tom se mluví méně, ale oceán tam může být taky) by mohl být život víceméně pozemského typu (toho hlubokomořského, ne fotosyntetizující). Na Enceladu by to asi byla výrazně větší exotika a na Titan už se předpokládá biochemie zcela nepodobná té na Zemi (a museli bychom pak zásadně přehodnotit naše představy o obyvatelnách zónach u exoplanet i "exoměsíců")

    Just how dangerous is it to travel at 20% the speed of light?
    Breakthrough Starshot has examined the impact of stray atoms, cosmic dust.
    Just how dangerous is it to travel at 20% the speed of light? | Ars Technica
    http://arstechnica.com/science/2016/08/could-breakthrough-starshots-ships-survive-the-trip/

    The space between here and the nearest star isn't completely empty. Earlier generations of stars have left a sparse collection of tiny dust particles,
    and various processes have left individual atoms scattered through the interstellar space. These particles pose very distinct risks, and the team worked
    through each separately.

    The main problem with running into an atom isn't the physical collision but rather the energy deposited in the spacecraft by the impact, which can cause
    local heating that damages the craft in two ways. When high enough, the heating causes the material the craft is made of to evaporate into space. Below
    that threshold, it can cause local melting, leading to a change in material properties as the area resolidifies.

    Globular clusters and halo assembly
    ATNF Daily Astronomy Picture

    Hierarchical accretion models for galaxy formation predict that the majority of stars in the halo of a spiral galaxy
    should have formed within dwarf galaxies that were later accreted by the larger galaxy. In 2010, we used a rough chemical
    tagging approach to identify stars in the Milky Way halo that had likely formed in globular clusters, using the light-element
    abundance anomalies that are well-studied in Galactic globular clusters.

    Fossilized rivers suggest warm, wet ancient Mars
    http://phys.org/news/2016-08-fossilized-rivers-ancient-mars.html
    Extensive systems of fossilised riverbeds have been discovered on an ancient region of the Martian surface, supporting the idea
    that the now cold and dry Red Planet had a warm and wet climate about 4 billion years ago, according to UCL-led research.
    The study, published in Geology and funded by the Science & Technology Facilities Council and the UK Space Agency, identified over
    17,000km of former river channels on a northern plain called Arabia Terra, providing further evidence of water once flowing on Mars.
