    Particle physicists detect a mysterious void inside Egypt’s Great Pyramid – GeekWire
    https://www.geekwire.com/2017/muon-big-void-egypt-great-pyramid/

    An international team of researchers has detected a mysterious, previously unknown void
    deep inside Egypt’s Great Pyramid that may be as large as an art gallery space.

    The anomalous space, known as the ScanPyramids Big Void, showed up on imagery produced
    by tracking concentrations of subatomic particles called muons as they zoomed through
    the pyramid’s stones.

    RNAAS: A Unique Journal Joins the Family
    http://aasnova.org/2017/11/01/rnaas-a-unique-journal-joins-the-family/

    Enter Research Notes of the American Astronomical Society (RNAAS) — a new and unique journal that just joined the AAS journal family
    this week. RNAAS provides a means of sharing with the astronomical community work that may not fit into traditional publication outlets.

    RNAAS is a non-peer-reviewed, non-edited journal that is moderated by one of the AAS journals’ lead editors, Dr. Chris Lintott (University
    of Oxford). Communications published in RNAAS are brief — they are limited to l.t. 1000 words, with space for one table or figure.

    Did our cosmos emerge from a sea of inflating bubbles? | Aeon Essays

    Maybe we don’t have to speculate about what life is like inside a bubble. It might be the only cosmic reality we know.

    https://www.nasa.gov/feature/jpl/martian-ridge-brings-out-rovers-color-talents

    Color-discerning capabilities that NASA's Curiosity rover has been using on Mars since 2012 are proving particularly helpful on a mountainside
    ridge the rover is now climbing.

    One of these methods for discerning targets' colors uses the Mast Camera (Mastcam); the other uses the Chemistry and Camera instrument (ChemCam).

    Each of the Mastcam's two eyes -- one telephoto and one wider angle -- has several science filters that can be changed from one image to the next
    to assess how brightly a rock reflects light of specific colors. By design, some of the filters are for diagnostic wavelengths that certain minerals
    absorb, rather than reflect. Hematite, one iron-oxide mineral detectable with Mastcam's science filters, is a mineral of prime interest as the rover
    examines "Vera Rubin Ridge."

    DESHIMA sees first light: a step closer to mapping the most distant star systems
    https://www.tudelft.nl/...a-sees-first-light-a-step-closer-to-mapping-the-most-distant-star-systems/

    DESHIMA is a completely new type of astronomical instrument with which a 3D map of the early universe can be constructed. In early October,
    Dutch and Japanese researchers installed the DESHIMA measurement instrument under the ASTE telescope in Chile. Over the past few days,
    DESHIMA has recorded light from an astronomical source for the first time. The development represents a significant milestone in the process
    of making the instrument operational.

    DESHIMA has been developed by TU Delft, SRON Netherlands Institute for Space Research and the Leiden Observatory, working together with
    a consortium of Japanese universities led by The University of Tokyo, and the National Astronomical Observatory of Japan (NAOJ).

    Aliens may be more like us than we think | University of Oxford
    http://www.ox.ac.uk/news/2017-10-31-aliens-may-be-more-us-we-think

    In a new study published in the International Journal of Astrobiology scientists from the University of Oxford show for the first time how
    evolutionary theory can be used to support alien predictions and better understand their behaviour. They show that aliens are potentially
    shaped by the same processes and mechanisms that shaped humans, such as natural selection.

    The theory supports the argument that foreign life forms undergo natural selection, and are like us, evolving to be fitter and stronger over time.

    Sam Levin, a researcher in Oxford’s Department of Zoology, said: ‘A fundamental task for astrobiologists (those who study life in the cosmos) is
    thinking about what extra-terrestrial life might be like. But making predictions about aliens is hard. We only have one example of life - life on
    Earth -- to extrapolate from. Past approaches in the field of astrobiology have been largely mechanistic, taking what we see on Earth, and what
    we know about chemistry, geology, and physics to make predictions about aliens.

    Astronomers Spy Planet-Spawning Vortex around Young Star - Scientific American
    https://www.scientificamerican.com/...icle/astronomers-spy-planet-spawning-vortex-around-young-star/

    In some respects, making a solar system might seem childishly simple. A cloud of gas and dust collapses under its own gravity,
    forming a whirling “protoplanetary” disk of debris that has a star at its center. Despite its name, though, a protoplanetary disk
    is a challenging environment in which to form worlds—at least, according to theorists who model the process. Now, however, new
    observations are revealing surprising details of how planets emerge from disks: the first worlds to form can give rise to whirlpool-
    like vortices, which create subsequent generations of planets. The findings were reported this month in The Astrophysical Journal Letters.

    Minerals containing water are widespread on Ceres, suggesting the dwarf planet may have had a global ocean in the past.
    What became of that ocean? Could Ceres still have liquid today? Two new studies from NASA's Dawn mission shed light on these questions.

    Space in Images - 2017 - 10 - Cloudy with a chance of protons
    http://www.esa.int/spaceinimages/Images/2017/10/Cloudy_with_a_chance_of_protons

    In September, Gaia unexpectedly detected a large quantity of protons – subatomic particles – emitted by a solar flare.

    In this image, captured by Gaia’s Wave Front Sensor – a sort of ‘camera within a camera’ in its main star-sensing instrument –
    the streaks of ‘snow’ are trails of individual protons. During normal space weather conditions, the image would only include
    one or two proton trails. The long trail running horizontally across the image indicates a particularly energetic proton.

    This proton storm was also reported by NASA’s GOES weather satellite, which is equipped with a particle-sensing instrument.

    ESA Science & Technology: Rosetta finds comet plume powered from deep below
    http://sci.esa.int/rosetta/59702-rosetta-finds-comet-plume-powered-from-deep-below/

    The plume was seen by ESA's Rosetta spacecraft on 3 July 2016, just a few months before the end of the mission
    and as Comet 67P/Churyumov–Gerasimenko was heading away from the Sun at a distance of almost 500 million km.

    Comet Mission Reveals "Missing Link" in our Understanding of Planet Formation
    http://www.ras.org.uk/...comet-mission-reveals-missing-link-in-our-understanding-of-planet-formation

    The missing link in our understanding of planet formation has been revealed by the first ever spacecraft to orbit and land on a comet,
    say German scientists. The study is published in a recent edition of the journal Monthly Notices of the Royal Astronomical Society.

    Professor Blum explains the implications of the team's observations "Our results show that only a single model for the formation of
    larger solid bodies in the young solar system may be considered for Chury. According to this formation model, 'dust pebbles' are
    concentrated so strongly by an instability in the solar nebula that their joint gravitational force ultimately leads to a collapse."

    This process forms the missing link between the well-established formation of 'dust pebbles' ('planetary building blocks' formed in
    the solar nebula by sticking collisions between dust and ice particles) and the gravitational accretion of planetesimals into planets,
    which scientists have pondered over for years.
