    Japan’s sixth HTV cargo mission slated for Sept. 30 launch – Spaceflight Now
    http://spaceflightnow.com/2016/07/27/japans-sixth-htv-cargo-mission-slated-for-sept-30-launch/
    Japan’s space agency has set Sept. 30 as the target launch date for the country’s sixth resupply mission to the International Space
    Station, carrying cargo, experiments and six lithium-ion batteries to kick off a major upgrade of the lab’s electrical system.

    The cylinder-shaped cargo craft is set for liftoff at 1716 GMT (1:16 p.m. EDT) Sept. 30 from the Tanegashima Space Center, a facility
    nestled on the southern coast of Tanegashima Island in southern Japan, the Japan Aerospace Exploration Agency announced Tuesday.

    The launch of the sixth H-2 Transfer Vehicle will occur in the predawn hours Oct. 1, Japanese time.

    Relation between Brown Dwarfs and Exoplanets
    http://arxiv.org/abs/1607.07922
    One of the most debated subjects in Astronomy since the discovery of exoplanets is how can we distinguish the most massive
    of such objects from very-low mass stars like Brown Dwarfs (BDs)? We have been looking for evidences of a difference in physical
    characteristics that could be related to different formation processes. Using a new diagnostic diagram that compares the baryonic
    gravitational potential (BGP) with the distances from their host stars, we have classified a sample of 355 well-studied exoplanets
    according to their possible structures.

    As NASA spacecraft explore deeper into space, onboard computer electronics must not only be smaller and faster, but also be prepared
    for extreme conditions. A prime example is shown in these images: a family of Application Specific Integrated Circuits, or ASICs, microchips
    specifically designed to measure the particles in space – the very stuff that can create radiation hazards for satellite computers.

    These tiny, radiation-resistant chips play a crucial role in one of the instruments nestled inside the radiation-shielded electronics vault
    on NASA’s Juno spacecraft – which entered Jupiter’s orbit on July 4. The microchips aboard Juno are part of the Jupiter Energetic Particle
    Detector Instrument, or JEDI, a cutting-edge instrument that will measure the composition of the immense magnetic system surrounding
    the planet, called a magnetosphere.

    Astronomers Gain New Insight into Magnetic Field Of Sun and Its Kin | NASA
    https://www.nasa.gov/...dra/astronomers-gain-new-insight-into-magnetic-field-of-sun-and-its-kin.html
    Astronomers have used data from NASA’s Chandra X-ray Observatory to make a discovery that may have profound implications
    for understanding how the magnetic field in the Sun and stars like it are generated.

    Researchers have discovered that four old red dwarf stars with masses less than half that of the Sun are emitting X-rays
    at a much lower rate than expected.

    X-ray emission is an excellent indicator of a star’s magnetic field strength so this discovery suggests that these stars
    have much weaker magnetic fields than previously thought.

    TESS:
    http://www.nasa.gov/feature/goddard/2016/nasas-tess-the-next-exoplanet-explorer
    As the search for life on distant planets heats up, NASA’s Transiting Exoplanet Survey Satellite (TESS) is bringing this hunt closer to home.
    Launching in 2017-2018, TESS will identify planets orbiting the brightest stars just outside our solar system using what’s known as the transit method.

    When a planet passes in front of, or transits, its parent star, it blocks some of the star's light. TESS searches for these telltale dips in brightness,
    which can reveal the planet's presence and provide additional information about it.

    TESS will be able to learn the sizes of the planets it sees and how long it takes them to complete an orbit. These two pieces of information are critical
    to understanding whether a planet is capable of supporting life. Nearly all other planet classifications will come from follow up observations, by both
    TESS team ground telescopes as well as ground- and space-based observations, including NASA's James Webb Space Telescope launching in 2018.

    White Dwarf Lashes Red Dwarf with Mystery Ray
    http://www.deepstuff.org/white-dwarf-lashes-red-dwarf-mystery-ray/
    Astronomers using the NASA/ESA Hubble Space Telescope, along with other telescopes on the ground and in space,
    have discovered a new type of exotic binary star: in the system AR Scorpii a rapidly spinning white dwarf star
    is powering electrons up to almost the speed of light. These high energy particles release blasts of radiation
    that lash the companion red dwarf star, and cause the entire system to pulse dramatically every 1.97 minutes
    with radiation ranging from the ultraviolet to radio.

    Isolated Young Star Seen by Spitzer and WISE - SpaceRef
    http://spaceref.com/astronomy/isolated-young-star-seen-by-spitzer-and-wise.html
    The unusual object, called CX330, was first detected as a source of X-ray light in 2009 by NASA's Chandra X-Ray Observatory
    while it was surveying the bulge in the central region of the Milky Way. Further observations indicated that this object was
    emitting optical light as well. With only these clues, scientists had no idea what this object was.

    But when Chris Britt, postdoctoral researcher at Texas Tech University in Lubbock, and colleagues were examining infrared
    images of the same area taken with NASA's Wide-field Infrared Survey Explorer (WISE), they realized this object has a lot
    of warm dust around it, which must have been heated by an outburst.

    Comparing WISE data from 2010 with Spitzer Space Telescope data from 2007, researchers determined that CX330 is likely a young
    star that had been outbursting for several years. In fact, in that three-year period its brightness had increased by a few hundred times.

    Old planets always get too hot or cold for life in the end | New Scientist
    https://www.newscientist.com/.../2099139-old-planets-always-get-too-hot-or-cold-for-life-in-the-end/
    Age matters. Searching for alien life on planets orbiting older stars may be fruitless because they always become prohibitively hot or cold.

    The search for life on other worlds has focused on planets in what’s known as the habitable zone – the ring around stars where it’s the right
    temperature for liquid water. That has led some to target planets orbiting red dwarf stars, as their smaller size and cooler temperatures mean
    planets in the habitable zone are closer in, and so easier to spot. But we should also look for planets whose stars are the right age,
    regardless of their size, say Shintaro Kadoya and Eiichi Tajika at the University of Tokyo, Japan.

    Torn-apart galaxy may be exacting revenge on the Milky Way | New Scientist
    https://www.newscientist.com/.../2099140-torn-apart-galaxy-may-be-exacting-revenge-on-the-milky-way/
    Simon Gibbons of the University of Cambridge and his colleagues have analysed the motion of stars in
    the Sagittarius streams to estimate that the galaxy originally possessed 60 billion solar masses.

    “This new more massive Sagittarius, if it’s right, could be the cause of the warp,” Gibbons says. Since
    the 1990s, astronomers have recognised that Sagittarius could warp the disc – if the satellite was massive
    enough.

    The Adaptive Optics Lucky Imager (AOLI) on the William Herschel Telescope (WHT) has obtained its first adaptive-optics closed-loop results,
    an important milestone in the development of this state-of-the-art instrument that aims at combining adaptive optics (AO) and lucky imaging
    (LI) to obtain the highest-ever resolution images at visible wavelengths from the ground.

    Astrobiologists debate which chemical signatures would hint at life on other worlds.
    Planet hunters seek new ways to detect alien life : Nature News & Comment
    http://www.nature.com/news/planet-hunters-seek-new-ways-to-detect-alien-life-1.20327
    In the search for life beyond Earth, false alarms abound. Researchers have generally considered, and rejected,
    claims ranging from a 1970s report of life on Mars to the 1990s ‘discovery’ of fossilized space microbes in a meteorite.

    Now, inspired by the detection of thousands of planets beyond the Solar System, NASA has started a fresh effort to learn
    how to recognize extraterrestrial life. The goal is to understand what gases alien life might produce — and how Earth-bound
    astronomers might detect such ‘biosignatures’ in light passing through the atmospheres of planets trillions of kilometres
    away (see ‘Searching for alien life’).
