    DRAGON: na cteni psanyho textu jsem odbornik:

    In contrast to our sun, the TRAPPIST-1 star–classified as an ultra-cool dwarf–is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system.

    Dragon Cargo Craft aborts ISS Rendezvous, New Attempt Thursday – Dragon SpX-10 | Spaceflight101
    http://spaceflight101.com/...on-spx10/dragon-cargo-craft-aborts-iss-rendezvous-new-attempt-thursday/

    The Dragon SpX-10 cargo spacecraft aborted its rendezvous with the International Space Station on Wednesday after encountering a problem
    with the Relative GPS navigation feature used by the approaching craft during the far-field rendezvous phase. Mission Controllers are planning
    to re-attempt the rendezvous on Thursday if the problem can be diagnosed in time.

    Fermi finds possible dark matter ties in Andromeda galaxy
    https://phys.org/news/2017-02-fermi-dark-ties-andromeda-galaxy.html

    NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence
    of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

    Surprisingly, the latest Fermi data shows the gamma rays in Andromeda—also known as M31—are confined to the galaxy's center instead of spread
    throughout. To explain this unusual distribution, scientists are proposing that the emission may come from several undetermined sources. One
    of them could be dark matter, an unknown substance that makes up most of the universe.

    "We expect dark matter to accumulate in the innermost regions of the Milky Way and other galaxies, which is why finding such a compact signal
    is very exciting," said lead scientist Pierrick Martin, an astrophysicist at the National Center for Scientific Research and the Research
    Institute in Astrophysics and Planetology in Toulouse, France. "M31 will be a key to understanding what this means for both Andromeda and
    the Milky Way."

    Experiments call origin of Earth's iron into question
    https://phys.org/news/2017-02-earth-iron.html

    New research from The University of Texas at Austin reveals that the Earth's unique iron composition isn't linked to the formation
    of the planet's core, calling into question a prevailing theory about the events that shaped our planet during its earliest years.

    The research, published in Nature Communications on Feb. 20, opens the door for other competing theories about why the Earth,
    relative to other planets, has higher levels of heavy iron isotopes. Among them: light iron isotopes may have been vaporized into
    space by a large impact with another planet that formed the moon; the slow churning of the mantle as it makes and recycles the Earth's
    crust may preferentially incorporate heavy iron into rock; or, the composition of the raw material that formed the planet in its earliest
    days may have been enriched with heavy iron.

    An isotope is a variety of atom that has a different weight from other atoms of the same element because it has a different numbers of neutrons.

    New data about two distant asteroids give a clue to the possible 'Planet Nine'
    https://phys.org/news/2017-02-distant-asteroids-clue-planet.html

    The dynamical properties of these asteroids, observed spectroscopiccally for the first time using the Gran Telescopio CANARIAS,
    suggest a possible common origin and give a clue to the existence of a planet beyond Pluto, the so-called 'Planet Nine.'

    Prediction: More gas-giants will be found orbiting Sun-like stars | Carnegie Institution for Science
    https://carnegiescience.edu/node/2147

    New planetary formation models from Carnegie’s Alan Boss indicate that there may be an undiscovered population of gas giant planets
    orbiting around Sun-like stars at distances similar to those of Jupiter and Saturn. His work is published by The Astrophysical Journal.

    The population of exoplanets discovered by ongoing planet-hunting projects continues to increase. These discoveries can improve models
    that predict where to look for more of them.

    The planets predicted by Boss in this study could hold the key to solving a longstanding debate about the formation of our Solar System’s
    giant planets out of the disk of gas and dust that surrounded the Sun in its youth.

    New insights on the nature of the star V501 Aurigae revealed
    https://phys.org/news/2017-02-insights-nature-star-v501-aurigae.html

    Astronomers have presented the results of new photometric and spectroscopic observations of the star V501 Aurigae
    (V501 Aur for short), providing new insights into the nature of this object. The findings show that V501 Aur,
    previously considered to be T-Tauri star, is most probably a field binary. The study was published Feb. 15
    in a paper available on arXiv.org.

    In the latest study, a team of astronomers led by Martin Vaňko of the Astronomical Institute of Slovak Academy
    of Sciences in Tatranská Lomnica, Slovakia, has found that V501 Aur is a single-lined spectroscopic binary star.
