    Solar System Exploration
    http://solarsystem.nasa.gov/news/2016/08/31/dawn-sets-course-for-higher-orbit
    After studying Ceres for more than eight months from its low-altitude science orbit,
    NASA's Dawn spacecraft will move higher up for different views of the dwarf planet.

    Dawn has delivered a wealth of images and other data from its current perch at 385 km
    above Ceres' surface, which is closer to the dwarf planet than the International Space
    Station is to Earth. Now, the mission team is pivoting to consider science questions
    that can be examined from higher up.

    Copernicus Sentinel-1A satellite hit by space particle / Sentinel-1 / Copernicus / Observing the Earth / Our Activities / ESA
    http://www.esa.int/...h/Copernicus/Sentinel-1/Copernicus_Sentinel-1A_satellite_hit_by_space_particle
    ESA engineers have discovered that a solar panel on the Copernicus Sentinel-1A satellite was hit by a millimetre-size particle in orbit on 23 August.
    Thanks to onboard cameras, ground controllers were able to identify the affected area. So far, there has been no effect on the satellite’s routine operations.

    A sudden small power reduction was observed in a solar array of Sentinel-1A, orbiting at 700 km altitude, at 17:07 GMT on 23 August. Slight changes in
    the orientation and the orbit of the satellite were also measured at the same time.

    UPDATE 8/29 at 8 PM EDT: The IMO has now reported that flow in the Múlakvísl River, which flows out from under Mýrdalsjökull,
    has increased and has high concentrations of sulfur dioxide and hydrogen sulfide. Both of these are common gases related to
    hydrothermal fluids (heated from magmatic sources). This is a common occurrence when earthquake swarms have disturbed the Katla
    caldera and is not likely directly linked to any change in eruption likelihood.

    Discovery one-ups Tatooine, finds twin stars hosting three giant exoplanets | Carnegie Institution for Science
    https://carnegiescience.edu/node/2084
    A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun.
    One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed.
    The findings, which may help explain the influence that giant planets like Jupiter have over a solar system’s architecture, have been accepted for publication in
    The Astronomical Journal.

    ESA Science & Technology: First stars formed even later than previously thought
    http://sci.esa.int/planck/58193-first-stars-formed-even-later-than-previously-thought/
    ESA's Planck satellite has revealed that the first stars in the Universe started forming later than previous observations
    of the Cosmic Microwave Background indicated. This new analysis also shows that these stars were the only sources needed
    to account for reionising atoms in the cosmos, having completed half of this process when the Universe had reached an age
    of 700 million years.

    Gaia Data Release set for 14 September | IEEC
    http://www.ieec.cat/uncategorized/gaia-data-release-set-for-14-september/
    The first Gaia data release, which will be available online on 14 September, will include the positions and
    G magnitude for about one billion stars using observations taken between 25 July 2014 and 16 September 2015.

    In addition, for a subset of data – about 2 million stars in common between the Tycho-2 Catalogue and Gaia –
    there will be a five-parameter astrometric solution, giving the positions, parallaxes, and proper motions for
    those objects. This is referred to as the Tycho-Gaia Astrometric Solution (TGAS).

    Photometric data for RR Lyrae and Cepheid variable stars that were observed frequently during a special scanning
    mode that repeatedly covered the ecliptic poles will also be made public.

    R.I.P.

    James W. Cronin, a physicist who shared a Nobel Prize for repudiating a fundamental principle of physics and
    explaining why the universe survived the Big Bang with anything in it, died on Thursday in St. Paul. He was 84.
