    Will Earth still exist 5 billion years from now? Old star offers sneak preview of the future – News
    http://www.kuleuven.be/...exist-5-billion-years-from-now-old-star-offers-sneak-preview-of-the-future

    What will happen to Earth when, in a few billion years’ time, the Sun is a hundred times bigger than it is today? Using the most powerful
    radio telescope in the world, an international team of astronomers has set out to look for answers in the star L2 Puppis. Five billion years
    ago, this star was very similar to the Sun as it is today.

    Third-ever natural quasicrystal found in Siberian meteorite | New Scientist
    https://www.newscientist.com/...2115570-third-ever-natural-quasicrystal-found-in-siberian-meteorite/

    There’s more than one way to cook a quasicrystal. For the first time, a new kind of this weird,
    rule-breaking solid has been found in nature without an identical compound having first been made in the lab.

    Paul Steinhardt at Princeton University has doggedly hunted for quasicrystals since he predicted their existence in the early 1980s.
    Before then, we only knew of two types of solids: crystals, in which every atom is arranged neatly in a repeating lattice, and amorphous
    solids, which have no such order. Quasicrystals are almost crystals, but they break the rules: their neat patterns never exactly repeat.

    A professional astrophysicist and an amateur astronomer have teamed up to reveal surprising details about an unusual millisecond
    pulsar (MSP) binary system comprising one of the fastest-spinning pulsars in our Galaxy and its unique companion star.

    The Universe Is Flat — Now What?
    http://www.space.com/34928-the-universe-is-flat-now-what.html

    The universe is flat. But there's a lot of subtlety packed into that innocent-looking statement.
    What does it mean for a 3D object to be "flat"? How do we measure the shape of the universe anyway?
    Since the universe is flat, is that…it? Is there anything else interesting to say?

    Galaxy's rapid growth spurt may have spawned 3000 suns per year | New Scientist
    https://www.newscientist.com/...5501-galaxys-rapid-growth-spurt-may-have-spawned-3000-suns-per-year/

    Great galaxies can grow up fast. Extreme quantities of magnesium in a quiet specimen far away reveal it was once
    one of the wildest star creators in the universe.

    The galaxy, named COSMOS 11494, is 10.7 billion light years away, so we see it when the universe was just 3.1 billion
    years old. It’s the most distant galaxy in which astronomers have measured the abundances of both magnesium and iron.

    United Nations General Assembly proclaims 30 June as International Asteroid Day
    http://www.unoosa.org/oosa/en/informationfor/media/2016-unis-os-478.html

    “The United Nations General Assembly proclaims June 30 as International Asteroid Day. We founded the annual event to raise awareness of the asteroid threat
    and opportunity to unite the human species behind a simple goal: Protect our planet from asteroid impacts. It is the only natural disaster we know how to
    prevent if we work together towards a global solution. We are all crew of Spaceship Earth.”

    Giant radio flare of Cygnus X-3 detected by astronomers
    http://phys.org/news/2016-12-giant-radio-flare-cygnus-x-.html

    Russian astronomers have recently observed a giant radio flare from a strong X-ray binary source known as Cygnus X-3
    (Cyg X-3 for short). The flare occurred after more than five years of quiescence of this source. The discovery was
    presented in a paper published Dec. 2 on the arXiv pre-print server.

    Temná hmota může být ve vesmíru rozložena rovnoměrněji | ESO Česko

    Pečlivá analýza snímků rozsáhlých oblastí oblohy pořízených dalekohledem VST přinesla překvapivý výsledek

    Analýza dat získaných v rámci rozsáhlé přehlídky galaxií, kterou v uplynulých letech prováděl dalekohled ESO/VST pracující na observatoři Paranal v Chile, naznačuje,
    že hustota temné hmoty ve vesmíru by mohla být nižší a její rozložení rovnoměrnější, než se dosud myslelo. Mezinárodní tým vědců využil snímky získané v rámci přehlídky
    KiDS (Kilo Degree Survey) k výzkumu vlivu gravitačního působení nejrozsáhlejších struktur hmoty ve vesmíru na světlo přicházející od patnácti milionů sledovaných
    vzdálených galaxií. Zdá se, že výsledky získané tímto způsobem jsou v rozporu se staršími závěry učiněnými na základě údajů z družice Planck.

    Project Starshot: Visiting the Nearest Star Within Our Lifetime

    Up Close at Alpha Centauri
    http://www.centauri-dreams.org/?p=36734
    In early December the Harvard-Smithsonian Center for Astrophysics offered as part of its fall colloquium series a talk by Harvard’s Avi Loeb,
    fortunately captured on YouTube as Project Starshot: Visiting the Nearest Star Within Our Lifetime. We’ve looked at Breakthrough Starshot in
    many posts on Centauri Dreams, including my reports from the last set of meetings in Palo Alto, but for those new to the concept of using
    a laser array to send small, instrumented sails to the Alpha Centauri stars, this video is a fine introduction.

    New telescope chip offers clear view of alien planets | ANU
    http://www.anu.edu.au/news/all-news/new-telescope-chip-offers-clear-view-of-alien-planets

    Scientists have developed a new optical chip for a telescope that enables astronomers to have a clear view of alien planets that may support life.

    Seeing a planet outside the solar system which is close to its host sun, similar to Earth, is very difficult with today's standard astronomical
    instruments due to the brightness of the sun. Associate Professor Steve Madden from The Australian National University (ANU) said the new chip
    removes light from the host sun, allowing astronomers for the first time to take a clear image of the planet.
