    XCHAOS: To sis mě s někým zaměnil. Na twitteru samotném mám paradoxně
    jen pár zdrojů (asteroidy/komety a historie astronomie, kosmon. a věd vůbec) Největší twitt.
    databázi mám na cs, protože při větším množství (cca 400 účtů) už mi twitter příjde strašně
    nepřehledný, proto databázi spravuji jinde, ale jde asi jen o zvyk.

    Jinak přehled o "sledovaných" jsem ztratil dávno, to už je pro mně irelevantní.. :) Ani na hlavní
    stránce jsem dlouho nebyl. Hnedle po připojení jdu rovnou po krku největším bourákům, abych
    to vůbec stíhal, a hlavní strana dokáže hodně zdržovat zbytečnostmi.

    .. ale zatím v drtivě většině vedeš ty :-)

    News | Asteroid Resembles Dungeons and Dragons Dice
    http://www.jpl.nasa.gov/news/news.php?feature=6742

    Radar images of asteroid 2017 BQ6 were obtained on Feb. 6 and 7 with NASA's 70-meter (230-foot) antenna at the Goldstone Deep Space Communications
    Complex in California. They reveal an irregular, angular-appearing asteroid about 660 feet (200 meters) in size that rotates about once every three
    hours. The images have resolutions as fine as 12 feet (3.75 meters) per pixel.

    "The radar images show relatively sharp corners, flat regions, concavities, and small bright spots that may be boulders," said Lance Benner of NASA's
    Jet Propulsion Laboratory in Pasadena, California, who leads the agency's asteroid radar research program. "Asteroid 2017 BQ6 reminds me of the dice
    used when playing Dungeons and Dragons. It is certainly more angular than most near-Earth asteroids imaged by radar."

    Asteroid 2017 BQ6 safely passed Earth on Feb. 6 at 10:36 p.m. PST (1:36 a.m. EST, Feb. 7) at about 6.6 times the distance between Earth and the moon
    (about 1.6 million miles, or 2.5 million kilometers). It was discovered on Jan. 26 by the NASA-funded Lincoln Near Earth Asteroid Research (LINEAR)
    Project, operated by MIT Lincoln Laboratory on the Air Force Space Command's Space Surveillance Telescope at White Sands Missile Range, New Mexico.

    XCHAOS: Skvělé! Na tohle info napjatě čekám od středy, ale prostě někdy
    už není čas řešit všechno (to mně fakt sejří, ale nic s tím nenadělám), takže pátrání po výsledcích
    konference (údajně velmi intenzivní a zajímavé!) byla má priorita na sobotu. Dík!

    Za Plutem už taky dobrý! :)

    NASA’s New Horizons spacecraft is operating normally after just over 24 hours in a protective “safe mode,” the result of a command-loading error
    that occurred early Thursday. The spacecraft is designed to automatically transition to safe mode under certain anomalous conditions to protect
    itself from harm. In safe mode, the spacecraft suspends its timeline of activities and keeps its antenna pointed toward Earth to listen for
    instructions from the Mission Operations Center at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland.

    Scientists estimate solar nebula’s lifetime | MIT News
    http://news.mit.edu/2017/scientists-estimate-solar-nebulas-lifetime-0209
    Study finds the swirling gas disk disappeared within the solar system’s first 4 million years.

    About 4.6 billion years ago, an enormous cloud of hydrogen gas and dust collapsed under its own weight, eventually flattening
    into a disk called the solar nebula. Most of this interstellar material contracted at the disk’s center to form the sun, and
    part of the solar nebula’s remaining gas and dust condensed to form the planets and the rest of our solar system.

    Now scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much
    of the solar system evolution took shape.

    Hubble finds big brother of Halley’s Comet ripped apart by white dwarf | ESA/Hubble
    http://www.spacetelescope.org/news/heic1703/

    Scientists using the NASA/ESA Hubble Space Telescope have observed, for the first time, a massive, comet-like object that has been
    ripped apart and scattered in the atmosphere of a white dwarf. The destroyed object had a chemical composition similar to Halley’s Comet,
    but was 100 000 times more massive than its famous counterpart.

    The international team of astronomers observed the white dwarf WD 1425+540, about 170 light-years from Earth in the constellation Boötes
    (the Herdsman). While studying the white dwarf’s atmosphere using both the NASA/ESA Hubble Space Telescope and the W. M. Keck Observatory
    the team found evidence that an object rather like a massive comet was falling onto the star, getting tidally disrupted while doing so.
