    Cassini: The Grand Finale: Cloud Bands Streak Across Titan
    https://saturn.jpl.nasa.gov/resources/7673/

    NASA's Cassini spacecraft captured this view of bands of bright, feathery methane clouds drifting across Saturn's moon Titan on May 7, 2017.

    The view was obtained during a distant (non-targeted) flyby, during which Cassini passed 488 000 kilometers above the moon's surface. Although
    Cassini will have no further close, targeted flybys of Titan, the spacecraft continues to observe the giant moon and its atmosphere from a distance.

    The dark regions at top are Titan's hydrocarbon lakes and seas.

    The image was taken on May 7, 2017, at a distance of 508 000 kilometers. The view is an orthographic projection centered on 57 degrees north latitude,
    48 degrees west longitude. An orthographic view is most like the view seen by a distant observer. Image scale is about 3 kilometers per pixel.

    Beyond the stars Green Bank telescopes search for signs of life - West Virginia Press Association : West Virginia Press Association
    http://wvpress.org/breaking-news/beyond-stars-green-bank-telescopes-search-signs-life/

    The GBT, completed in 2000, is taller than the Statue of Liberty, the Great Pyramids of Giza and just smaller than the Washington Monument.
    The surface area of the dish itself is 2.3 acres. The entire telescope is on wheels — 16 to be exact — and weighs almost 17 million pounds.

    That makes it the heaviest wheel and track system in the world. And unlike the other telescopes, the dish of the GBT moves. In fact, it always moves.

    “It can move 360 degrees all the way around,” Holstine said. “But we generally only move it 270 degrees because in the center of this is a cable wrap,
    but it can see the whole sky.” The part of the dish that doesn’t move side-to-side moves up and down, going from 95 degrees all the way to 4 degrees.

    “It can see 85 percent of the celestial sphere,” Holstine said. “Almost everything there is to see in the universe.”

    The Scientific Truth About Planet Nine, So Far
    https://www.forbes.com/...rtswithabang/2017/05/09/the-scientific-truth-about-planet-nine-so-far/amp/

    ...The full suite of data allows us to place better restrictions on where we think Planet Nine ought to be, and the most likely scenarios place it somewhere
    in the constellation of Taurus. As we approach the June solstice, that constellation becomes more visible, meaning that the coming months will be the best time
    for potential Planet Nine-hunters, both amateur and professional, to get to work. Mike Brown is also keeping a blog, himself, about the current status of
    the efforts to find Planet Nine; despite his wild optimism about the scenario, his reporting thus far is accurate and not overhyped.

    News | NASA Delivers Detectors for ESA's Euclid Spacecraft
    https://www.jpl.nasa.gov/news/news.php?feature=6840

    Three detector systems for the Euclid mission, led by ESA (European Space Agency), have been delivered to Europe for the spacecraft's near-infrared instrument.
    The detector systems are key components of NASA's contribution to this upcoming mission to study some of the biggest questions about the universe, including
    those related to the properties and effects of dark matter and dark energy -- two critical, but invisible phenomena that scientists think make up the vast
    majority of our universe.

    News | Merging Galaxies Have Enshrouded Black Holes
    https://www.jpl.nasa.gov/news/news.php?feature=6841

    Black holes get a bad rap in popular culture for swallowing everything in their environments. In reality, stars,
    gas and dust can orbit black holes for long periods of time, until a major disruption pushes the material in.

    A merger of two galaxies is one such disruption. As the galaxies combine and their central black holes approach
    each other, gas and dust in the vicinity are pushed onto their respective black holes. An enormous amount of high-
    energy radiation is released as material spirals rapidly toward the hungry black hole, which becomes what
    astronomers call an active galactic nucleus (AGN).

    A study using NASA's NuSTAR telescope shows that in the late stages of galaxy mergers, so much gas and dust falls
    toward a black hole that the extremely bright AGN is enshrouded. The combined effect of the gravity of the two
    galaxies slows the rotational speeds of gas and dust that would otherwise be orbiting freely. This loss of energy
    makes the material fall onto the black hole.

    Surprise! When a brown dwarf is actually a planetary mass object | Carnegie Institution for Science
    https://carnegiescience.edu/news/surprise-when-brown-dwarf-actually-planetary-mass-object

    Sometimes a brown dwarf is actually a planet—or planet-like anyway. A team led by Carnegie’s Jonathan Gagné,
    and including researchers from the Institute for Research on Exoplanets (iREx) at Université de Montréal,
    the American Museum of Natural History, and University of California San Diego, discovered that what astronomers
    had previously thought was one of the closest brown dwarfs to our own Sun is in fact a planetary mass object.
    Their results are published by The Astrophysical Journal Letters.

    http://www.almaobservatory.org/en/visuals/images/astronomy?g2_itemId=3656

    This view shows a new picture of the dust ring around the bright star Fomalhaut from ALMA.
    The underlying blue picture shows an earlier picture obtained by the NASA/ESA Hubble Space
    Telescope. The new ALMA image has given astronomers a major breakthrough in understanding
    a nearby planetary system and provided valuable clues about how such systems form and evolve.
    Note that ALMA has so far only observed a part of the ring.

    UCLA GCG data for stars around the Supermassive Black Hole at the Center of the Milky Way

    This demo shows the observed and predicted orbits of thirteen stars that were used by astronomers at the Keck/UCLA Galactic Center Group
    to predict the position of a huge black hole at the center of the Milky Way. This data was provided by Andrea Ghez and Jessica Lu.

    At a ceremony today, CERN inaugurated its linear accelerator, Linac 4, the newest accelerator acquisition since the Large Hadron Collider (LHC).
    Linac 4 is due to feed the CERN accelerator complex with particle beams of higher energy, which will allow the LHC to reach higher luminosity by 2021.
    After an extensive testing period, Linac 4 will be connected to CERN’s accelerator complex during the upcoming long technical shut down in 2019-20.
    Linac 4 will replace Linac 2, which has been in service since 1978. It will become the first step in CERN’s accelerator chain, delivering proton
    beams to a wide range of experiments.

    ANU scientists say the early Earth was likely to be barren, mountainless and almost entirely under water with a few small islands,
    following their analysis of tiny mineral grains as old as 4.4 billion years. Lead researcher Dr Antony Burnham said the team studied
    zircon mineral grains that were preserved in sandstone rocks in the Jack Hills of Western Australia and which were the oldest
    fragments of the Earth ever found.

    Scientists Think These Ancient Carvings Depict an Apocalyptic Comet Impact - Motherboard

    Deciphering the mysterious “Vulture Stone” at the 11,500-year-old ruins of Göbekli Tepe.

    The harrowing tale of an apocalyptic comet impact may be etched into the pillars of the earliest known temple,
    Göbekli Tepe in southern Turkey, erected by humans some 11,500 years ago.

    Excavation of this site over the last two decades has uncovered megaliths carved with depictions of animals
    and humans, pushing back the timeline of human civilization, and attracting researchers hoping to decode
    the meaning of these perplexing pictograms.
