    Chandra :: Photo Album :: GJ 176 :: September 6, 2017
    http://chandra.harvard.edu/photo/2017/gj176/

    A new study using data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton suggests X-rays emitted by a planet's host star
    may provide critical clues to just how hospitable a star system could be. A team of researchers looked at 24 stars similar to the Sun,
    each at least one billion years old, and how their X-ray brightness changed over time.

    Since stellar X-rays mirror magnetic activity, X-ray observations can tell astronomers about the high-energy environment around the star.
    In the new study the X-ray data from Chandra and XMM-Newton revealed that stars like the Sun and their less massive cousins calm down
    surprisingly quickly after a turbulent youth.

    The Rosetta space probe discovered a large amount of organic material in the nucleus of comet “Chury.” In an article published by MNRAS on August 31,
    2017, two French researchers advance the theory that this matter has its origin in interstellar space and predates the birth of the Solar System.

    New Horizons Files Flight Plan for 2019 Flyby
    https://www.nasa.gov/feature/new-horizons-files-flight-plan-for-2019-flyby

    NASA’s New Horizons mission has set the distance for its New Year’s Day 2019 flyby of Kuiper Belt object 2014 MU69,
    aiming to come three times closer to MU69 than it famously flew past Pluto in 2015.

    That milestone will mark the farthest planetary encounter in history – some one billion miles (1.5 billion kilometers)
    beyond Pluto and more than four billion miles (6.5 billion kilometers) from Earth. If all goes as planned, New Horizons
    will come to within just 2,175 miles (3,500 kilometers) of MU69 at closest approach, peering down on it from celestial
    north. The alternate plan, to be employed in certain contingency situations such as the discovery of debris near MU69,
    would take New Horizons within 6,000 miles (10,000 kilometers)— still closer than the 7,800-mile (12,500-kilometer)
    flyby distance to Pluto.

    Accretion-powered pulsar reveals unique timing glitch
    http://www.ras.org.uk/news-and-press/3041-accretion-powered-pulsar-reveals-unique-timing-glitch

    A group of scientists from the Middle East Technical University and Başkent University in Turkey have discovered a sudden change in
    the rotation speed of the peculiar pulsar SXP 1062. These jumps in frequency, known as ‘glitches’, are commonly seen in isolated pulsars,
    but have so far never been observed in binary pulsars (pulsars orbiting with a companion white dwarf or neutron star) such as SXP 1062.

    SXP 1062 is located in the Small Magellanic Cloud, a satellite galaxy of our own Milky Way galaxy, and one of our nearest intergalactic
    neighbours at 200,000 light years away. Lead author of the study, Mr M. Miraç Serim, a senior PhD student working under the supervision
    of Prof Altan Baykal, said, “This pulsar is particularly interesting, since as well as orbiting its partner star as part of a binary pair,
    it is also still surrounded by the remnants of the supernova explosion which created it.”

    Study of Uranus suggests some of its moons are on a collision course
    https://phys.org/news/2017-09-uranus-moons-collision.html

    A trio of researchers, two with the University of Idaho, the other with Wellesley College,
    has found evidence suggesting that two pairs of Uranus's moons are on a collision course.
    Robert Chancia, Matthew Hedman and Richard French have uploaded a paper describing their
    observations to the arXiv preprint server.

    https://www.nasa.gov/feature/goddard/2017/two-significant-solar-flares-imaged-by-nasas-sdo

    The sun emitted two significant solar flares on the morning of Sept. 6, 2017. The first peaked at 5:10 a.m. EDT and the second, larger flare,
    peaked at 8:02 a.m. EDT. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured images of both events. Solar flares
    are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on
    the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel.

    Could TRAPPIST-1’s seven Earth-like planets have gas giant siblings? | Carnegie Institution for Science
    https://carnegiescience.edu/node/2230

    New work from a team of Carnegie scientists (and one Carnegie alumnus) asked whether any gas giant planets could potentially orbit
    TRAPPIST-1 at distances greater than that of the star’s seven known planets. If gas giant planets are found in this system’s outer
    edges, it could help scientists understand how our own Solar System’s gas giants like Jupiter and Saturn formed.

    Earlier this year, NASA’s Spitzer Space Telescope thrilled the world as it revealed that TRAPPIST-1, an ultra-cool dwarf star in
    the Aquarius constellation, was the first-known system of seven Earth-sized planets orbiting a single star. Three of these planets
    are in the so-called habitable zone—the distance from the central star at which liquid water is most likely to be found.

    But it’s possible that like our own Solar System, TRAPPIST-1 is also orbited by gas giant planets at a much-greater distance than
    the Earth-sized planets that we already know are part of the system.

    By following up on mysterious high-energy sources mapped out by NASA's Fermi Gamma-ray Space Telescope, the Netherlands-based Low Frequency
    Array (LOFAR) radio telescope has identified a pulsar spinning at more than 42,000 revolutions per minute, making it the second-fastest known.

    Shocking discovery explains powerful novae | MSUToday | Michigan State University
    http://msutoday.msu.edu/news/2017/shocking-discovery-explains-powerful-novae/

    In a typical year, there are around 50 novae, nuclear explosions on the surface of white dwarf stars, in our galaxy.
    Some of these explosions are so bright and powerful, they exceed the scale of scientific explanation.

    Employing two powerful telescopes, astronomers at Michigan State University have proven a theory that explains these
    super-luminous novae and other astronomical explosions. The results, published in the current issue of Nature Astronomy,
    indicate that powerful shockwaves amplify the explosions beyond any traditional scale for nuclear explosions.

    “Astronomers have long thought the energy from novae was dominated by the white dwarf, controlling how much light and
    energy are emitted,” said Laura Chomiuk, MSU astronomer and study co-author. “What we discovered, however, was a completely
    different source of energy – shockwaves that can dominate the entire explosion.”

    As the explosion begins, it ejects a cooler, slower wave of gaseous material, relatively speaking. Behind it, though, is a hot,
    fast wave speeding right behind it. The collision of the two ejections produces a shockwave, which results in a spectacular
    explosion of heat and light.

    Massive black hole discovered near heart of the Milky Way | Science | The Guardian

    Astronomers find evidence of enormous black hole one hundred thousand times more massive than the sun in a gas cloud near the galaxy’s centre

    An enormous black hole one hundred thousand times more massive than the sun has been found hiding in a toxic gas cloud wafting around near
    the heart of the Milky Way. If the discovery is confirmed, the invisible behemoth will rank as the second largest black hole ever seen in
    the Milky Way after the supermassive black hole known as Sagittarius A* that is anchored at the very centre of the galaxy.

    And West Aussie researchers are at the forefront of this search, as part of an Australian-wide project to detect a particle called the axion.

    The search for extraterrestrial intelligence (SETI) has been going for more than 50 years, with ever more sophisticated detection systems
    and creative ideas about how E.T. might come calling. Astronomers haven’t heard anything yet, but perhaps it’s only a matter of time.
    Check out what they’ve been looking for, how they would know if they found it and what the aftermath might be.
