    K2’s First Five-Planet System
    http://aasnova.org/2016/08/08/k2s-first-five-planet-system/
    Led by Andrew Vanderburg (NSF Graduate Research Fellow at the Harvard-Smithsonian Center for Astrophysics), a team of scientists recently
    analyzed K2 observations of the bright star HIP 41378. The team found that this F-type star hosts five potential planetary candidates

    Asteroid-Bound Spacecraft and its Ride Take Strides Toward September Launch | OSIRIS-REx Mission
    http://blogs.nasa.gov/...steroid-bound-spacecraft-and-its-ride-take-strides-toward-september-launch/
    Inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida, technicians have installed thermal blankets
    around the spacecraft (pictured above), culminating with a solar array illumination test today. These activities set the stage for spacecraft
    closeouts, weighing and fueling, planned for next week.

    Kepler team restarts powered-down photometer
    http://phys.org/news/2016-08-kepler-team-restarts-powered-down-photometer.html
    During a scheduled contact with NASA's Kepler space telescope on Thursday, July 28, the team found the photometer—the camera onboard the spacecraft—powered off.
    The photometer was turned on again and the flight system returned to autonomous science operations on Monday, Aug. 1. They will confirm that science operations
    have been resumed within a week. The team is currently investigating the cause; the spacecraft is otherwise operating normally.

    A planet greeting from the danger zone | astrobites
    https://astrobites.org/2016/08/08/a-planet-greeting-from-the-danger-zone/
    “A new exoplanet has been detected.” While this message would have triggered tremendous excitement among astronomers a few years ago,
    it speaks for the huge success of exoplanetary detections that by today the message has become daily news. In this respect, the result
    of today’s article is nothing special: Yet another detection of an exoplanet. Nevertheless, this detection is worthy of being featured
    on astrobites because the detected exoplanet K2-39b seems to be exceptional. What makes it special is the fact that this planet orbits
    an old star on at the smallest distance ever observed so far.

    Small gas cloud caught blowing a huge bubble in the Milky Way | New Scientist
    https://www.newscientist.com/...00157-small-gas-cloud-caught-blowing-a-huge-bubble-in-the-milky-way/
    Halfway across the Milky Way, a gas cloud has punched a hole in the galaxy, leaving a blast wave and a gaping void 3000 light years across.

    Compared with our galaxy, this cloud, named CHVC040, is a lightweight: only 16,000 times the mass of the sun. It is moving at high velocity
    and should have disintegrated on impact with the galactic disc, according to simulations, so it’s a mystery how it created this hole.

    New methodology provides better size estimates of meteorite impact craters
    http://phys.org/news/2016-08-methodology-size-meteorite-impact-craters.html
    Using newly developed methodology, planetary scientists from Western University have re-estimated the diameter of eight well-known impact
    craters on Earth. The journal Science Advances published an explanation of the new technique and the improved estimations today.

    Astronomers offer a new bucket list for other worlds
    http://phys.org/news/2016-08-astronomers-bucket-worlds.html
    Lisa Kaltenegger, professor of astronomy and director of Cornell's Carl Sagan Institute, lead author Stephen Kane of San Francisco State University
    and other scientists have written "A Catalog of Kepler Habitable Zone Exoplanet Candidates," which will be published in a forthcoming Astrophysical
    Journal – listing more than two dozen possibly perfectly placed planets with potential to have liquid water or even life.
    Nearly 3,500 exoplanets have been found by NASA's Kepler mission – launched seven years ago to survey the Milky Way.
    "We're trying to make interstellar travel just a little bit easier," Kaltenegger quipped. "These exoplanets are the first ones we'd like to examine –
    with more to come – as every day we're finding more. These are the first few pages in our ever-expanding travel guide."

    Evidence mounts that neutrinos are the key to the universe's existence
    http://phys.org/news/2016-08-evidence-mounts-neutrinos-key-universe.html
    New experimental results show a difference in the way neutrinos and antineutrinos behave, which could explain why matter persists over antimatter.

    The universe lived through a prolonged "Dark Ages" until hydrogen reionized.
    Now, researchers are closer to figuring out when that happened.

    The changing length of the shadow marks the passing of the seasons on Saturn. As the planet nears its northern-hemisphere solstice in May 2017, the shadow will
    get even shorter. At solstice, the shadow's edge will be about 45 000 kilometers from the planet's surface, barely making it past the middle of the B ring.
