    A new study may have found a link between dark energy and the Second Law of Thermodynamics—
    suggesting that the very expansion of the universe may impart a direction to time.

    The rise and fall of galaxy formation | Carnegie Institution for Science
    https://carnegiescience.edu/node/2083
    An international team of astronomers, including Carnegie’s Eric Persson, has charted the rise and fall of galaxies over 90 percent of cosmic history.
    Their work, which includes some of the most sensitive astronomical measurements made to date, is published by The Astrophysical Journal.
    The FourStar Galaxy Evolution Survey (ZFOURGE) has built a multicolored photo album of galaxies as they grow from their faint beginnings into mature
    and majestic giants. They did so by measuring distances and brightnesses for more than 70,000 galaxies spanning more than 12 billion years of cosmic
    time, revealing the breadth of galactic diversity.

    Three concentric supernova remnants found in nearby galaxy.
    http://www.slate.com/...y/2016/08/30/three_concentric_supernova_remnants_found_in_nearby_galaxy.html
    Astronomers have found the expanding debris from not one, but three previously unknown supernovae. Better yet: The spherical shells of gas hurled outward
    by these explosions are concentric, centered on the same point in space, which means all three stars were very close to each other when they let go.

    This weird triple supernova was found using a technique that specifically looks for rapidly moving gas. It involves a special kind of spectrograph that
    breaks the incoming light for the sky into very narrow slices of color. The resulting spectrum can reveal a lot of information about an object, including
    its composition, speed through space, and more.

    Chandra :: Photo Album :: CL J1001 :: August 30, 2016
    http://chandra.si.edu/photo/2016/clj1001/
    This image contains the most distant galaxy cluster, a discovery made using data from NASA's Chandra X-ray Observatory
    and several other telescopes. The galaxy cluster, known as CL J1001+0220, is located about 11.1 billion light years from
    Earth and may have been caught right after birth, a brief, but important stage of cluster evolution never seen before.

    Search for Planet Nine turns up three mini-worlds
    http://www.geekwire.com/2016/search-planet-nine-turns-three-mini-planets/
    The list includes these mini-worlds:

    2014 SR349, which is in the kind of extreme orbit that could hypothetically have been perturbed by Planet Nine.

    2013 FT28, which isn’t quite as much in the sweet spot for Planet Nine action, dynamically speaking.

    2014 FE72, which is said to be the first identified object from the faraway Oort Cloud with an orbit entirely beyond Neptune. The orbit
    is stretched out far enough to take it more than 3,000 times farther away from the sun than Earth is. The astronomers say its orbital
    path seems likely to be influenced by gravitational forces beyond the solar system, such as passing stars or the galactic tide.

    The map shows Cassini imaging coverage of Titan as of June 2015. This map was produced by the USGS Astrogeology Science Center

    For years, astronomers have puzzled over a massive star lodged deep in the Milky Way that shows conflicting signs of being extremely old and extremely young.
    Researchers initially classified the star as elderly, perhaps a red supergiant. But a new study by a NASA-led team of researchers suggests that the object,
    labeled IRAS 19312+1950, might be something quite different – a protostar, a star still in the making.

    SETI Investigating Signal From Sun-Like Star 95 Light-Years Away — NOVA Next | PBS
    http://www.pbs.org/...a/next/space/seti-investigating-signal-from-sun-like-star-95-light-years-away/
    Over the weekend, astronomers trained their telescopes a relatively close star, hoping
    for more evidence of a curious signal heard over a year ago by Russian radio telescope operators.

    First detected on May 15, 2015—but only just now reported to other SETI scientists—the 11 GHz signal
    appears to have originated from HD 164595, a star with 0.99 solar masses and known to have at least
    one planet orbiting it, a so-called “warm Neptune.”

    Hunt for ninth planet reveals new extremely distant solar system objects
    http://phys.org/news/2016-08-ninth-planet-reveals-extremely-distant.html
    In the race to discover a proposed ninth planet in our Solar System, Carnegie's Scott Sheppard and Chadwick Trujillo
    of Northern Arizona University have observed several never-before-seen objects at extreme distances from the Sun in
    our Solar System. Sheppard and Trujillo have now submitted their latest discoveries to the International Astronomical
    Union's Minor Planet Center for official designations. A paper about the discoveries has also been accepted to
    The Astronomical Journal.

    Featured Image: The Milky Way’s X
    http://aasnova.org/2016/08/29/featured-image-the-milky-ways-x/
    This contrast-enhanced image of the Milky Way, observed by the Wide-Field Infrared Survey Explorer (WISE),
    clearly reveals that the bulge of stars at the center of our galaxy is shaped like a large “X”. The boxy
    nature of the Milky Way’s bulge was revealed by satellite image in 1995, but in recent years, star counts
    along the line of sight toward the bulge have suggested that the bulge may be X-shaped.
