Ta ett dopp i Lagunnebulosan
GigaGalaxy Zoom del 3
28 september 2009
ESO-projektet GigaGalaxy Zooms tredje och sista bild har precis släppts. Nu blir det en djupdykning in i 370 megapixlar av interstellär skönhet då Lagunnebulosan står i fokus. Den nya bilden återfinns tillsammans med två tidigare bilder, på hela natthimlen och Vintergatans centrum, på GigaGalaxy Zooms hemsida www.gigagalaxyzoom.org.
Lagunnebulosan ligger fyra till fem tusen ljusår bort i Skyttens stjärnbild. Nebulosan är ett gigantiskt 100 ljusår brett moln där stjärnor håller på att bildas. De mörka fläckar utspridda över hela nebulosan är i själva verket moln av gas och stoft där det snart kommer att födas hopar av nya, glödande, unga stjärnor. Några av de minsta molnen kallas 'globuler' och de har katalogiserats av astronomen Edward Emerson Barnard.
Bilden, som täcker ett område på natthimlen åtta gånger månens storlek, är tagen med MPG/ESO 2,2 meters teleskopet vid La Silla-observatoriet i Chile. Teleskopets 67-megapixel kamera WFI (Wide Field Imager) ligger bakom många minnesvärda astronomiska bilder.
Lagunen är också värd för en ung stjärnhop med katalognamnet NGC 6530. Stjärnhopen är hem för mellan 50 och 100 stjärnor som gnistrar i en tät klunga nedan till vänster på bilden. Troligen ligger denna stjärnhop en bit framför Lagunnebulosans färgglada gasmoln.
The name of the Lagoon Nebula derives from the wide lagoon-shaped dark lane located in the middle of the nebula that divides it into two glowing sections.
Detta magnifika stjärnlandskap är den sista av de tre riktigt stora bilderna som utgör projektet GigaGalaxy Zoom, som lanseras av ESO för att markera Internationella astronomiåret 2009. Med de här tre bilderna visar GigaGalaxy Zoom upp hela natthimlen som den ser ut för människoögat från jordens mörkaste öknen, för att sedan zooma in mot Vintergatans praktfulla centrum med ett amatörteleskop, och till slut rikta ett proffsteleskop mot en välkänd nebulosas detaljrika molnslöjor. Projektet länkar samman stjärnhimlen som alla kan se om natten med det djupa, dolda kosmos som astronomer forskar om. Bildernas skönhet njuter vi av tack vare den praktfulla natthimmel ovan ESO:s observatorier i Chile, som är de mest produktiva i världen.
-GigaGalaxy Zoom har varit mycket framgångsrikt och lockat hundratusentals besökare från hela världen, säger projektsamordnaren Henri Boffin. Nu när trilogin är fulländad kan besökarna på hemsidan utforska en underbart detaljerad kosmisk miljö på många olika skalor och göra en hisnande djupdykningen in i Vintergatan.
