    Spitzer slavi 10 let ve vesmiru. CG :)
    Jde o posledni ze ctyr observatori, ktere NASA vypustila na obeznou drahu Zeme, a to 25/8/2003.
    (Predesle tri byly vicepasmovy HST, uz nefunkcni Compton [obor gamma zareni] a rentgenova
    Chandra). Teleskop se zrcadlem o prumeru 0.85m prosel slozitym procesem prejmenovavani:
    Puvodni oznaceni znelo SIRTF (Space Infrared Telescope Facility), pozdeji byl z duvodu lepsiho
    vyslovovani prejmenovan na SST (Spitzer Space Telescope), nese tedy jmeno astrofyzika Lymana
    Spitzera, ktery prisel s napadem tohoto druhu teleskopu uz v roce 1946.
    I pres ubytek chladiciho media jsou stale nektere jeho pristroje funkcni.

    U tohoto mi spadla celist...okoli marsovskeho krateru Gusev (misto, kde pristaval Spirit),
    snimany sondou Mars Express. Vpravo dole je krasne videt elipticky stin mesice Phobos.

    Update on the Bright Nova Delphini 2013; Plus a Gallery of Images from our Readers
    http://www.universetoday.com/...bright-nova-delphini-2013-plus-a-gallery-of-images-from-our-readers/





    BRIGHT NOVA: Nova Delphini, which exploded just four days ago in the northern constellation Delphinus,
    has continued to brighten. With a magnitude of +4.5, it is now easily visible in binoculars even from
    urban areas if you know where to look. This cactus in Tucson, Arizona, points the way:

    Good morning! Little-known space fact: Soyuz astronauts get 2 enemas prior to launch. Imagine if that was needed before every long drive...

    It's because the Soyuz toilet is ... basic. The human interface part is the apparatus on the left.

    Uzasna kratka video sekvence zakrytu Deimosu Phobosem (slozena ze 41 snimku MastCam)
    Martansky sol trva 24h + 40 min, Phobos ma delku obezne periody asi 7.5h, takze se pohybuje
    rychle ve smeru zapad-vychod, Deimosova doba orbity cini 30 hodin, takze se zdanlive pohybuje
    retrogradne. To je dobre viditelne na videu, ale ted mi poprve doklaplo, proc nektere zdroje
    uvadeli retrogradni pohyb Deimosu!!!! (resilo se to i nekde tu...)
