T\u00e4htitieteilij\u00e4t kertovat l\u00f6yt\u00e4neens\u00e4 t\u00e4ysin uudentyyppisen avaruuden kohteen. \u201dT\u00e4m\u00e4 on tarina ep\u00e4onnistuneesta galaksista\u201d, kertoo Alejandro Benitez-Llambay.\u00a0 <\/p>\n

Hubble-avaruusteleskooppi on tutkinut kaasupitoista pime\u00e4n aineen pilve\u00e4. Lempinimen Cloud-9 saanut kohde on todenn\u00e4k\u00f6isesti j\u00e4\u00e4nne varhaisesta galaksien muodostuksesta.\u00a0\n<\/p>\n

Kattavasta etsinn\u00e4st\u00e4 huolimatta Hubble ei l\u00f6yt\u00e4nyt pilvest\u00e4 t\u00e4hti\u00e4.\n<\/p>\n

\u201dTieteess\u00e4 opimme yleens\u00e4 enemm\u00e4n ep\u00e4onnistumisista kuin onnistumisista”, valaisee Alejandro Benitez-Llambay<\/strong> Milanon Bicocca-yliopistosta.\n<\/p>\n

”T\u00e4ss\u00e4 tapauksessa t\u00e4htien puuttuminen todistaa teorian oikeaksi. Se kertoo meille, ett\u00e4 olemme l\u00f6yt\u00e4neet muodostumatta j\u00e4\u00e4neen galaksin alkuper\u00e4isen rakennuspalikan.\u201d\n<\/p>\n

Cloud-9 on ensimm\u00e4inen varmistettu havainto t\u00e4m\u00e4nkaltaisesta kohteesta.\n<\/p>\n

Pilvess\u00e4 on vetykaasua noin miljoonan Auringon massan verran. Pime\u00e4\u00e4 ainetta on kuitenkin valtavasti enemm\u00e4n, arviolta viiden miljardin Auringon massan verran.\n<\/p>\n

Tulevaisuudessa Cloud-9 saattaa tuottaa t\u00e4hti\u00e4, jos se kasvaa paljon massiivisemmaksi. Jos pilvi toisaalta olisi ollut selv\u00e4sti kevyempi, se olisi luultavasti hajaantunut jo kauan sitten.\u00a0\n<\/p>\n
