    http://www.nasa.gov/feature/new-research-reveals-fluctuating-atmosphere-of-jupiter-s-volcanic-moon
    Jupiter’s volcanic moon Io has a thin atmosphere that collapses in the shadow of Jupiter, condensing as ice, according to a new study by
    NASA-funded researchers. The study reveals the freezing effects of Jupiter’s shadow during daily eclipses on the moon’s volcanic gases.

    “This research is the first time scientists have observed this remarkable phenomenon directly, improving our understanding of this
    geologically active moon,” said Constantine Tsang, a scientist at the Southwest Research Institute in Boulder, Colorado. The study was
    published Aug. 2 in the Journal of Geophysical Research.

    Io is the most volcanically active object in the solar system. The volcanoes are caused by tidal heating, the result of gravitational
    forces from Jupiter and other moons. These forces result in geological activity, most notably volcanoes that emit umbrella-like plumes
    of sulfur dioxide gas that can extend up to 300 miles (480 kilometers) above Io and produce extensive basaltic lava fields that can
    flow for hundreds of miles.

    Finding Wolf-Rayet Stars in the Galaxy, their Environments and Implications for High-Mass Star Formation. » An Eye on the Universe
    https://blogs.stsci.edu/...-galaxy-their-environments-and-implications-for-high-mass-star-formation/
    Wolf-Rayet (WR) stars are believed to be evolved massive stars that initially started their lives with masses of more than 20 Msun. With such high masses,
    they evolve very quickly to the WR state from high-mass hydrogen burning O stars in 1-2Myr. Currently, evidence suggests that the majority of WR stars are
    either in or affected by having been in relative close binaries, that can affect their evolution.

    A giant stellar void in the Milky Way
    http://phys.org/news/2016-08-giant-stellar-void-milky.html
    A major revision is required in our understanding of our Milky Way Galaxy according to an international team led by Prof Noriyuki Matsunaga
    of the University of Tokyo. The Japanese, South African and Italian astronomers find that there is a huge region around the centre of our
    own Galaxy, which is devoid of young stars. The team publish their work in a paper in Monthly Notices of the Royal Astronomical Society.

    Optical and radio astrometry of the galaxy associated with FRB150418
    ATNF Daily Astronomy Picture
    http://www.atnf.csiro.au/ATNF-DailyImage/archive/2016/02-Aug-2016.html
    A fading radio source, coincident in time and position with the fast radio burst FRB 150418, has been associated with the galaxy WISE J071634.59-190039.2.
    Subsequent observations of this galaxy have revealed that it contains a persistent, but variable, radio source. Bassa et al. present e-MERLIN, VLBA, and
    ATCA radio observations and Subaru optical observations of WISE J071634.59-190039.2 and find that the persistent radio source is unresolved and must be
    compact (less than 0.01 kpc), and that its location is consistent with the optical centre of the galaxy. They conclude that it is likely that WISE J071634.59 190039.2
    contains a weak radio AGN.

    Explore LHC data on new ATLAS educational platform | CERN
    http://home.cern/about/updates/2016/08/explore-lhc-data-new-atlas-educational-platform
    On Friday, 29 July, the ATLAS experiment at CERN released the data from 100 trillion proton-proton collisions to the public.
    This is the world’s first open release of 8 TeV data, which was gathered using the Large Hadron Collider in 2012.
    In parallel with the data release, ATLAS has launched a comprehensive educational platform to guide university-level students
    and teachers on how to use the data and the corresponding analysis tools. With the extensive documentation provided, users
    can follow worked examples using the ATLAS open dataset and carry out analyses on their own.

    Faintest hisses from space reveal famous star's past life
    http://phys.org/news/2016-08-faintest-hisses-space-reveal-famous.html
    Astronomers have managed to peer into the past of a nearby star millions of years before its famous explosion,
    using a telescope in remote outback Australia at a site free from FM radio interference.
    Research by an international team including astronomers at the International Centre of Radio Astronomy Research (ICRAR)
    observing the region at the lowest-ever radio frequencies has helped fine-tune our understanding of stellar explosions.
    The research paints a picture of the star's life long before its death in what was the closest and brightest supernova
    seen from Earth, now known as supernova remnant 1987A, which collapsed spectacularly almost 30 years ago.

    Why Gamma Ray Bursts Are the Most Epic of All Apocalyptic Scenarios | Motherboard
    http://motherboard.vice.com/...d/why-gamma-ray-bursts-are-the-most-epic-of-all-apocalyptic-scenarios
    Asteroid impacts. Nuclear war. Unhinged climate change. These are all respectable, solid entries into the great pantheon
    of doomsday scenarios that could wipe out life on Earth.

    But when it comes to sheer destructive flair, gamma ray bursts (GRBs) take the apocalyptic cake. Forged in catastrophic
    cosmic disruptions like supernovae and neutron star mergers, GRBs are the brightest phenomena in the universe. Capable of
    releasing more energy in a single second than the Sun will in its entire lifetime of ten billion years, these bursts are
    essentially the universe’s unique riff on projectile barfing.

    Is Earthly Life Premature from a Cosmic Perspective?2016-17 | www.cfa.harvard.edu/
    https://www.cfa.harvard.edu/news/2016-17
    The universe is 13.8 billion years old, while our planet formed just 4.5 billion years ago. Some scientists think this time gap means that life on other
    planets could be billions of years older than ours. However, new theoretical work suggests that present-day life is actually premature from a cosmic perspective.

    "If you ask, 'When is life most likely to emerge?' you might naively say, 'Now,'" says lead author Avi Loeb of the Harvard-Smithsonian Center for Astrophysics.
    "But we find that the chance of life grows much higher in the distant future."

    Life as we know it first became possible about 30 million years after the Big Bang, when the first stars seeded the cosmos with the necessary elements like carbon
    and oxygen. Life will end 10 trillion years from now when the last stars fade away and die. Loeb and his colleagues considered the relative likelihood of life
    between those two boundaries.
