    Why Does Time Seem to Fly as We Get Older? - The Crux
    http://blogs.discovermagazine.com/crux/2016/08/11/why-time-flies-older-you-get/
    There are several theories which attempt to explain why our perception of time speeds up as we get older. One idea is a gradual alteration of our internal
    biological clocks. The slowing of our metabolism as we get older matches the slowing of our heartbeat and our breathing. Children’s biological pacemakers beat
    more quickly, meaning that they experience more biological markers (heartbeats, breaths) in a fixed period of time, making it feel like more time has passed.

    Another theory suggests that the passage of time we perceive is related to the amount of new perceptual information we absorb. With lots of new stimuli our
    brains take longer to process the information so that the period of time feels longer. This would help to explain the “slow motion perception” often reported
    in the moments before an accident. The unfamiliar circumstances mean there is so much new information to take in.

    Tak jsem se byl na chvíli mrknout na oblohu, než půjdu spát a lítá to pěkně. Až zapadne po půlnoci Měsíc, tak to bude parádní, škoda, že musím ráno vstávat.
    Ale měl jsem štěstí na jeden velký, který v maximu byl jasnější než všecky hvězdy a pár sekund po tom bylo krásně vidět, jak dohasínal a rudnul.
    Přeju všem krásné pozorování, jasnou oblohu a Měsíc pod obzorem ;)

    NASA to Map Asteroid Bennu from the Ground Up
    https://www.nasa.gov/feature/goddard/2016/nasa-to-map-asteroid-bennu-from-the-ground-up
    The OSIRIS-REx Laser Altimeter, or OLA, is provided by the Canadian Space Agency and will be used
    to create three-dimensional global topographic maps of Bennu and local maps of candidate sample sites.

    “OLA will measure the asteroid’s topography and shape in a detail that is unprecedented compared to other
    asteroid missions," said Michael Daly, OLA instrument scientist at York University in Toronto, Canada.
    "This 3-D shape will be the foundational dataset for the other instruments.”

    The Infinity Paradox - One Universe at a Time
    https://briankoberlein.com/2016/08/11/the-infinity-paradox/
    No matter what direction you look in the night sky, it looks basically the same. In astronomy terms we say the Universe is homogeneous and isotropic.
    Sure there are areas where galaxies cluster together, and other areas where galaxies are rare, but on average the distribution of stars is pretty even.
    Because of this, an early idea for the cosmos is that it is the same everywhere forever. It seems both ageless and infinite in expanse. But if that’s
    the case it raises a few troubling paradoxes.

    The Predictor of Pulsar Timing | astrobites
    https://astrobites.org/2016/08/10/the-predictor-of-pulsar-timing/
    The gravitational-wave Universe has at long last been unlocked: LIGO’s recent observations of gravitational radiation from binary black hole mergers
    have given astronomers a new means to observe the cosmos. With the influx of papers that pursued these detections over the past half year, it is easy
    to assume that gravitational-wave physics is a research topic exclusive to recent times. In reality, this research field has a rich history, and the
    methods used to detect gravitational waves were developed over many decades. For example, the idea of using interferometers like LIGO for gravitational-
    wave detection got its roots in the 1960s, and took nearly half a century to evolve from an idea to an observation. Today’s Astrobite will take us back
    to a classic astrophysical paper that delivered a crucial result for the future of gravitational-wave astronomy.

    Moons orbiting the exoplanet Beta Pic b may be visible in 2017.
    http://www.slate.com/...16/08/11/moons_orbiting_the_exoplanet_beta_pic_b_may_be_visible_in_2017.html
    The star in question is Beta Pictoris, which is about 60 light years away (that’s relatively close). It’s more massive, hotter, and
    brighter than the Sun. It’s also considerably younger: It’s about 25 million years old, while our star is over 4.5 billion years in age.

    Spotting the Solar eclipse on the Space Station | Outpost 42
    http://outpost42.esa.int/blog/spotting-the-solar-eclipse-on-the-space-station/
    This Friday, parts of the northern hemisphere will be shrouded in darkness as the Moon moves in between the Sun and the Earth.

    For ESA astronaut Samantha Cristoforetti and her crewmates on the International Space Station don’t have to worry about clouds
    getting in the way of their view. From their orbit above Earth 400 km high they will have a great view of the eclipse.
