    Bad News for Life: TRAPPIST-1 Planets' Atmospheres May Have Been Destroyed
    https://www.space.com/37530-trappist-1-planets-atmospheres-stripped.html

    The potentially Earth-like planets in the TRAPPIST-1 system may not be so conducive to life after all, two new studies report.

    Intense radiation and particles streaming from their host star have likely taken a huge toll on all seven of these worlds, even the three that
    apparently lie within the "habitable zone," where liquid water could theoretically exist on a planet's surface, according to the new research.

    "Because of the onslaught by the star's radiation, our results suggest the atmosphere on planets in the TRAPPIST-1 system would largely be destroyed,"
    Avi Loeb, co-author of one of the studies, said in a statement. "This would hurt the chances of life forming or persisting," added Loeb, who chairs
    Harvard's astronomy department and who also works at the Harvard-Smithsonian Center for Astrophysics (CfA).

    Exciting New Images | Lunar Reconnaissance Orbiter Camera
    http://www.lroc.asu.edu/posts/978

    Twenty new shapefiles created by the Lunar Reconnaissance Orbiter Camera (LROC) team are now available. A shapefile is a common format for vector data:
    points, lines, or polygons that represent features such as the locations of the Apollo landers, the linear lobate scarps, and the footprints of Narrow
    Angle Camera digital terrain models.

    MASCARA
    ESOcast 117 Light: Eyes Wide Open for New Exoplanet Hunter (4K UHD) | ESO United States
    http://www.eso.org/public/usa/videos/eso1722a/

    The MASCARA (Multi-site All-Sky CAmeRA) station at ESO’s La Silla Observatory in Chile has achieved first light.
    This new facility will seek out transiting exoplanets as they pass in front of their bright parent stars and
    create a catalogue of targets for future exoplanet characterisation observations.

    Exoplanet hunter sees first light at ESO’s La Silla Observatory

    In June 2016, ESO reached an agreement with Leiden University to site a station of MASCARA at ESO’s La Silla Observatory
    in Chile, taking advantage of the excellent observing conditions of the southern hemisphere skies. This station is now
    made its first successful test observations.

    Gamma-ray Telescopes Reveal a High-energy Trap in Our Galaxy's Center
    https://www.nasa.gov/...rd/2017/gamma-ray-telescopes-reveal-a-high-energy-trap-in-our-galaxys-center

    A combined analysis of data from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System (H.E.S.S.),
    a ground-based observatory in Namibia, suggests the center of our Milky Way contains a "trap" that concentrates some of the
    highest-energy cosmic rays, among the fastest particles in the galaxy.

    "Our results suggest that most of the cosmic rays populating the innermost region of our galaxy, and especially the most
    energetic ones, are produced in active regions beyond the galactic center and later slowed there through interactions with
    gas clouds," said lead author Daniele Gaggero at the University of Amsterdam. "Those interactions produce much of the gamma-
    ray emission observed by Fermi and H.E.S.S."

    Pozorovatelé z týmu New Horizons hlásí úspěch:

    Stín uloven!

    Vzdálená planetka 2014 MU69 již potřetí zmobilizovala mezinárodní tým astronomů, kteří 17. července v Argentině rozmístili síť svých přenosných dalekohledů. Do usilí zpozorovat, jak planetka na okamžik zakryje vzdálenou hvězdu, se zapojila také místní vláda, která astronomům poskytla nemalou podporu. I díky tomu přináší jedna z nejambicióznějších pozorovacích kampaní v historii své ovoce!

    https://www.nasa.gov/feature/nasa-s-new-horizons-team-strikes-gold-in-argentina

    A primitive solar system object that’s more four billion miles (6.5 billion kilometers) away passed in front of a distant star as seen from Earth.
    Just before midnight Eastern Time Sunday (12:50 a.m. local time July 17), several telescopes deployed by the New Horizons team in a remote part of
    Argentina were in precisely the right place at the right time to catch its fleeting shadow — an event that’s known as an occultation.

    In a matter of seconds, NASA’s New Horizons team captured new data on its elusive target, an ancient Kuiper Belt object known as 2014 MU69. Weary
    but excited team members succeeded in detecting the spacecraft’s next destination, in what’s being called the most ambitious and challenging ground
    occultation observation campaign in history.

    Astronomers discover Earth-sized exoplanet with very short orbital period
    https://phys.org/news/2017-07-astronomers-earth-sized-exoplanet-short-orbital.html

    An international team of astronomers has detected a new Earth-sized exoplanet in an ultra-short period around its parent star.
    The alien world, designated EPIC 228813918 b, circles its host every four hours and 20 minutes, which makes it the second-shortest
    orbital period of a planet known to date. The finding was presented in a paper published July 14 on arXiv.org.

    EPIC 228813918 b was identified by a group of researchers led by Alexis Smith of German Aerospace Center's (DLR) Institute
    of Planetary Research in Berlin, Germany. The transit signal was detected using NASA's prolonged Kepler mission, known as K2,
    during its Campaign 10, lasting from July 6 to September 20, 2016.

    11 Scientific Advances Of The Past 100 Years Gave Us Our Entire Universe
    https://www.forbes.com/...c-advances-of-the-past-100-years-gave-us-our-entire-universe/#6c72ecd04128

    Exactly 100 years ago, our conception of the Universe was far different from what it is today. The stars within the Milky Way were known,
    and were known to be at distances up to thousands of light years away, but nothing was thought to be further. The Universe was assumed to be static,
    as the spirals and ellipticals in the sky were assumed to be objects contained within our own galaxy. Newton's gravity still hadn't been overthrown
    by Einstein's new theory, and scientific ideas like the Big Bang, dark matter, and dark energy hadn't even been thought up yet. But during each decade,
    huge advances were made, all the way up to the present day. Here's a highlight of how each one moved our scientific understanding of the Universe forward.

    A medium-sized (M2) solar flare and a coronal mass ejection (CME) erupted from the same, large active region of the sun on July 14, 2017. The flare
    lasted almost two hours, quite a long duration. The coils arcing over this active region are particles spiraling along magnetic field lines, which
    were reorganizing themselves after the magnetic field was disrupted by the blast. Images were taken in a wavelength of extreme ultraviolet light.

    Asteroid 2012 TC4 to Safely Pass Earth This October
    https://cneos.jpl.nasa.gov/news/news197.html

    A small asteroid designated 2012 TC4 will pass very close to Earth on Oct. 12, and even though scientists cannot yet predict exactly
    how close it will approach, they are certain that the asteroid will fly by at a safe distance from our planet. This asteroid has not
    been seen since the week it was discovered in October 2012, when it sped past Earth at about one-fourth the distance from Earth to
    the moon. Estimated to be only 30 to 100 feet (10 to 30 meters) in size, the asteroid has been too distant and too faint to be detected
    over the last five years. As it starts to approach Earth this summer, large telescopes will be used to re-establish its precise trajectory.
    The new observations are expected to help refine knowledge about its orbit, narrowing the uncertainty about how far it will be from Earth
    at its closest approach in October.

    From brightness measurements made during the week it was observed in 2012, the size of this asteroid is estimated to be in the range of 30
    to 100 feet (10 meters to 30 meters). For comparison, the asteroid that hit Earth’s atmosphere near Chelyabinsk, Russia, in February 2013
    was roughly 70 feet (20 meters) across.
