    Hi-C to Show the Sun’s Corona in Sharp Detail | NASA
    http://www.nasa.gov/...ll/news/news/releases/2016/hi-c-to-show-the-sun-s-corona-in-sharp-detail.html
    Update ( 3 p.m. EDT, July 19, 2016) – The launch of the Hi-C payload on a NASA Black Brant IX suborbital sounding rocket has been postponed. A new launch
    date has not been determined. The team discovered a potential payload system issue during pre-launch testing. The team is currently assessing the problem.

    NASA and its partners are getting ready to launch a rocket-borne camera to the edge of space at 12:36 p.m. Mountain time on July 19, 2016, on its second
    flight to study the sun. The clarity of images returned will provide scientists around the world with clues to one of the biggest questions in heliophysics
    – why the sun’s atmosphere, or corona, is so much hotter than its surface.

    Planet Nine may have tilted entire solar system except the sun | New Scientist
    https://www.newscientist.com/...8029-planet-nine-may-have-tilted-entire-solar-system-except-the-sun/
    A jealous Planet Nine may have shoved its siblings for attention. If a massive ninth planet
    exists in our solar system, it might explain why the planets are out of line with the sun.

    The eight major planets still circle the sun in the original plane of their birth. The sun
    rotates on its own axis, but surprisingly, that spin is tilted: the axis lies at an angle of
    6 degrees relative to a line perpendicular to the plane of the planets.

    The inclination of the planetary system relative to the solar equator may be explained by the presence of Planet 9

    https://www.scientificamerican.com/...-in-space-could-explain-mysterious-cold-spot-in-the-universe/
    To glimpse the oldest light in the universe, simply tune an old television between channels: the tiny specs dancing on the screen result from the antenna
    being bombarded relentlessly by photons that were emitted shortly after the big bang, some 13.8 billion years ago. These photons fly uniformly through space
    from all directions, with an average temperature of 2.7 kelvins (°455 degrees Fahrenheit), composing a cloud of radiation called the cosmic microwave background
    (CMB). Because these photons are so old, the familiar two-dimensional map of the CMB is often called a “baby picture” of the universe, providing a window back
    into the primordial conditions that created the cosmos we see around us today.

    Attempt to explain away ‘dark energy’ takes a hit | Science | AAAS
    http://www.sciencemag.org/news/2016/07/attempt-explain-away-dark-energy-takes-hit
    For nearly 20 years, physicists have known that the expansion of the universe has begun to speed up.
    This bizarre acceleration could arise because some form of mysterious dark energy is stretching space.
    Or, it could signal that physicists' understanding of gravity isn't quite right. But a new study puts
    the screws on a broad class of alternative theories of gravity, making it that much harder to explain
    away dark energy.

    The study is also path setting because it exploits an effect called weak lensing in which the gravity
    from closer galaxies distorts the images of more distant ones. "That's the future," says Bob Nichol,
    an observational cosmologist at the University of Portsmouth in the United Kingdom who was not involved
    in the study. "If you look to the next decade, there's going to be an explosion of this data."

    In 1968, husband and wife team Charles and Ray Eames created “Powers of Ten”,
    an educational short film influenced by the 1957 book by Kees Boeke, Cosmic View:
    The Universe in Forty Jumps. This famous film was one the first video’s, if not
    the very first, to put the observable universe into perspective.

    U.S. and Russian Scientists Are Making Plans to Go Back to the Moon Together
    What U.S.-Russian cooperation in space might look like in ten years: a moon base.

    American and Russian engineers are getting closer to a new plan for cooperating in space, one that would go beyond low Earth orbit
    and preserve the multinational alliance forged at the dawn of the International Space Station program in 1993. Organizations on
    both sides are quietly toying with the idea of going back to the moon together. That is, if politics don't get in the way.

    With the ISS scheduled to make a controlled plunge into the ocean in 2024, the partners have been preparing to go their own ways.
    NASA, while funding companies like SpaceX to go to orbit, is developing the Orion spacecraft and the super-heavy rocket called Space
    Launch System (SLS) for manned missions into deep space and potentially as far as Mars. The European Space Agency (ESA) jumped on
    NASA's bandwagon few years ago, agreeing to contribute the service and propulsion module for the Orion. But the second-largest ISS
    contributor, Russia, has so far remained uncommitted to any joint venture beyond the station.

    X marks the spot at the center of the Milky Way galaxy
    http://phys.org/news/2016-07-center-milky-galaxy.html
    Two astronomers—with the help of Twitter—have uncovered the strongest evidence yet that an enormous X-shaped structure
    made of stars lies within the central bulge of the Milky Way Galaxy.

    Previous computer models, observations of other galaxies, and observations of our own galaxy have suggested that the X-shaped structure existed.
    But no one had observed it directly; and some astronomers argued that previous research that pointed indirectly to the existence of the X could
    be explained in other ways.
    "There was controversy about whether the X-shaped structure existed," says Dustin Lang, a Research Associate at the Dunlap Institute for Astronomy
    & Astrophysics, University of Toronto, and co-author of the paper describing the discovery. "But our paper gives a good view of the core of our
    own galaxy. I think it has provided pretty good evidence for the existence of the X-shaped structure."
    The results appear in the July issue of the Astronomical Journal. The lead author is Melissa Ness, a postdoctoral researcher at the Max Planck
    Institute for Astronomy in Heidelberg.

    Ancient rocks reveal how Earth recovered from mass extinction
    http://phys.org/news/2016-07-ancient-reveal-earth-recovered-mass.html
    Scientists have shed light on why life on Earth took millions of years to recover from the greatest mass extinction of all time.

    The study provides fresh insight into how Earth's oceans became starved of oxygen in the wake of the event 252 million years ago,
    delaying the recovery of life by five million years.
    Findings from the study are helping scientists to better understand how environmental change can have disastrous consequences for
    life on Earth. The Permian-Triassic Boundary extinction wiped out more than 90 per cent of marine life and around two thirds of
    animals living on land. During the recovery period, Earth's oceans became starved of oxygen - conditions known as anoxia.
    Previous research suggested the mass extinction and delayed recovery were linked to the presence of anoxic waters that also
    contained high levels of harmful compounds known as sulphides.

    Hot Jupiter-esque Discovery Hints at Planet Formation W. M. Keck Observatory
    http://www.keckobservatory.org/recent/entry/hot_jupiter_esque_discovery_hints_at_planet_formation
    A team of astronomers discovered a Jupiter-like planet within a young system that could serve as a decoder ring for understanding
    how planets formed around our sun. The W. M. Keck Observatory on Maunakea, Hawaii confirmed the discovery. The findings were headed
    by Bruce Macintosh, a professor of physics at Stanford University, and show the new planet, 51 Eridani b, is one million times fainter
    than its parent star and shows the strongest methane signature ever detected on an alien planet, which should yield additional clues
    as to how the planet formed. The results are published in the current issue of Science.
