    DRAGONFotografie z vesmíru a kosmonautiky +videa

    Explanation: It was an astronomical triple play. Setting on the left, just after sunset near the end of last month, was our Moon -- showing a bright crescent phase. Setting on the right was Venus, the brightest planet in the evening sky last month -- and this month, too. With a small telescope, you could tell that Venus' phase was half, meaning that only half of the planet, as visible from Earth, was exposed to direct sunlight and brightly lit. High above and much further in the distance was the Pleiades star cluster. Although the Moon and Venus move with respect to the background stars, the Pleiades do not -- because they are background stars. In the beginning of this month, Venus appeared to move right in front of the Pleiades, a rare event that happens only once every eight years. The featured image captured this cosmic triangle with a series of exposures taken from the same camera over 70 minutes near Avonlea, Saskatchewan, Canada. The positions of the celestial objects was predicted. The only thing unpredicted was the existence of the foreground tree -- and the astrophotographer is still unsure what type of tree that is.

    Evropsko-japonská sonda BepiColombo zdraví pozemšťany.
    Dnes v 6:25 SELČ se sonda prosmýkla kolem Země ve vzdálenosti 12 700 km a tím ohla svoji trajektorii ke středu sluneční soustavy. Dnes to bylo naposledy, co se BepiColombo podívala k Zemi. :)
    Sondy (jsou to dvě spojené sondy a přeletový modul) mají za úkol později zkoumat Merkur.

    A tady pěkné video ukazující snímky z průletu: https://mobile.twitter.com/ESA_Bepi/status/1248590737912070144

    Probably the best sprite of 2018 for me.
    A beautiful big jellyfish sprite over Kaw Lake, Oklahoma. They are the largest, fastest and most intricate of the sprites. So quick in fact only one of the three cameras caught it.
    Amazing just how much goes unseen out there unless we have a camera pointed at it

    The Murchison meteorite fell to earth near Murchison, Victoria, in Australia, in 1969. It's 4.6 billion years old and likely existed before the Earth itself had completely formed. It contains common amino acids sas well as unusual ones

    WERT: Srandičky, ale skutečně ty integrovaný obvody vyráběla ta firma Singer, která dneska dělá hlavně šicí stroje :-) V 60. letech pohltili firmu Friden Inc., která do té doby dělala elektromechanický a elektronický kalkulačky, a pokračovali v tom.
