    Now in HD: the Earth’s Turbulent Core | CNRS News
    https://news.cnrs.fr/articles/now-in-hd-the-earths-turbulent-core

    Taking a deep dive into our planet’s turbulent core 3000 kilometers below surface level, geophysicists have
    emerged with high-definition 3D simulations showing the hidden mechanisms that govern the Earth’s magnetic field.

    Fastest stars in the Milky Way are ‘runaways’ from another galaxy | University of Cambridge
    http://www.cam.ac.uk/research/news/fastest-stars-in-the-milky-way-are-runaways-from-another-galaxy

    A group of astronomers have shown that the fastest-moving stars in our galaxy – which are travelling so fast
    that they can escape the Milky Way – are in fact runaways from a much smaller galaxy in orbit around our own.

    The researchers, from the University of Cambridge, used data from the Sloan Digital Sky Survey and computer simulations to demonstrate
    that these stellar sprinters originated in the Large Magellanic Cloud (LMC), a dwarf galaxy in orbit around the Milky Way.

    These fast-moving stars, known as hypervelocity stars, were able to escape their original home when the explosion of one star in a binary
    system caused the other to fly off with such speed that it was able to escape the gravity of the LMC and get absorbed into the Milky Way.
    The results are published in the Monthly Notices of the Royal Astronomical Society, and will be presented today (5 July) at the National
    Astronomy Meeting in Hull.

    Astronomers first thought that the hypervelocity stars, which are large blue stars, may have been expelled from the centre of the Milky Way
    by a supermassive black hole. Other scenarios involving disintegrating dwarf galaxies or chaotic star clusters can also account for the speeds
    of these stars but all three mechanisms fail to explain why they are only found in a certain part of the sky.

    To date, roughly 20 hypervelocity stars have been observed, mostly in the northern hemisphere, although it’s possible that there are many more
    that can only be observed in the southern hemisphere.

    Shocking case of indigestion in supermassive black hole
    http://www.ras.org.uk/news-and-press/3010-shocking-case-of-indigestion-in-supermassive-black-hole

    A multi-wavelength study of a pair of colliding galaxies has revealed the cause of a supermassive black hole's case of 'indigestion'. Results will be presented
    by Dr Hayden Rampadarath at the National Astronomy Meeting at the University of Hull. Once every couple of hundred million years, the small galaxy NGC 5195 falls
    into the outer arms of its larger companion, NGC 5194, also known as the Whirlpool galaxy. Both galaxies are locked in a gravitational dance that will result –
    billions of years in the future – in the formation of a single galaxy.

    As NGC 5195 plunges into the Whirlpool, matter streams onto the supermassive black hole at NGC 5195's centre and forms an accretion disc. The disc grows to a point
    where the supermassive black hole can no longer accrete or 'digest' efficiently and matter is blasted out into the surrounding interstellar medium. Last year, NASA's
    Chandra X-Ray observatory spotted arcs of X-ray emission that appeared to result from this 'force-feeding'.

    Now, new high-resolution images of the core of NGC 5195, taken with the e-MERLIN radio array, and archive images of the surrounding area from the Very Large Array
    (VLA), Chandra and the Hubble Space Telescope, reveal in detail how these blasts occur and spread. The study was led by astronomers at the University of Manchester's
    Jodrell Bank Centre for Astrophysics.

    'Little Cub' gives astronomers rare chance to see galaxy demise
    https://news.ucsc.edu/2017/07/little-cub-galaxy.html

    A primitive galaxy that could provide clues about the early universe has been spotted by astronomers as it begins to be consumed by a gigantic neighboring galaxy.

    The Little Cub galaxy--so called because it sits in the Ursa Major or Great Bear constellation--is being stripped of the gas needed to continue forming stars by
    its larger companion. The find means scientists now have a rare opportunity to observe a dwarf galaxy as its gas is removed by the effects of a nearby giant galaxy
    to learn more about how this process happens. As the Little Cub has remained almost pristine since its formation, scientists also hope its elements will reveal more
    about the chemical signature of the universe just minutes after the Big Bang. The research, carried out by UC Santa Cruz and Durham University, UK, is being presented
    on Tuesday, July 4, at the Royal Astronomical Society's National Astronomy Meeting.

    The Little Cub and its larger neighbor, a spiral galaxy called NGC 3359, are about 200 to 300 thousand light years apart, and approximately 50 million light years
    from Earth. Gas from the Little Cub is being stripped away by its interaction with NGC 3359, which has up to 10,000 times as many stars as the Little Cub and is
    similar to our Milky Way. By observing this cosmic feast, scientists hope to understand more about how and when gas is lost from smaller galaxies.

    Hidden red dwarf discovered in dust of giant star | University of Hertfordshire
    http://www.herts.ac.uk/about-us/news/2017/july/hidden-red-dwarf-discovered-in-dust-of-giant-star

    Observations of the brightest star in the infrared sky by a team of astronomers, including researchers
    from the University of Hertfordshire, have revealed that the dust surrounding it hides a small red dwarf star.

    CW Leonis, a red giant star 500 times the size of the Sun is located in the Leo constellation 300 light years away.
    This is an evolving star that is ejecting significant amounts of dust forming an enveloping cloud many times the size
    of our solar system. It has been the subject of hundreds of studies over the years, but only now has the existence
    of a smaller red dwarf star been found within the dust cloud.

    From 1994 to 2000, using a one meter telescope at the Observatory of Torino, Professor Richard Smart at the University
    of Hertfordshire observed a minute wobble in the motion of CW Leonis that defied explanation. This wobble was very small -
    equivalent to the side of a 10p coin on the Moon as seen from the Earth - but it was detectable.

    A recent study of the dust around CW Leonis revealed a swirl pattern that was hypothesised to be due to the presence of
    an unseen companion star. Introducing the companion resolved the 17-year-old mystery of the wobble. The research has
    been accepted for publication in Monthly Notices of the Royal Astronomical Society (MNRAS).

    Pulsar Candidate in Andromeda

    NASA's Nuclear Spectroscope Telescope Array, or NuSTAR, has identified a candidate pulsar in Andromeda - the nearest large galaxy to the Milky Way.
    This likely pulsar is brighter at high energies than the Andromeda galaxy's entire black hole population. The inset image shows the pulsar candidate
    in blue, as seen in X-ray light by NuSTAR. The background image of Andromeda was taken by NASA's Galaxy Evolution Explorer in ultraviolet light.

    Andromeda is a spiral galaxy like our Milky Way but larger in size. It lies 2.5 million light-years away in the Andromeda constellation.
