Hubble-avaruusteleskooppi on ottanut t\u00e4m\u00e4n upean kuvan j\u00e4ttim\u00e4isest\u00e4 kaasupilvest\u00e4, jota kirkas nuori t\u00e4hti valaisee. Kuva osoittaa, kuinka rajua t\u00e4htien muodostumisprosessin loppuvaihe voi olla, kun nuori t\u00e4hti ravistelee ymp\u00e4rist\u00f6\u00e4\u00e4n.<\/p>\n<\/div>\n

Vesiper\u00e4inen nuori t\u00e4hti, nimelt\u00e4\u00e4n S106 IR, sijaitsee vetykaasupilven sis\u00e4ll\u00e4 ja heitt\u00e4\u00e4 ainetta ulos suurella nopeudella, mik\u00e4 h\u00e4iritsee sit\u00e4 ymp\u00e4r\u00f6iv\u00e4\u00e4 kaasua ja p\u00f6ly\u00e4. T\u00e4hden massa on noin 15 kertaa Auringon massa, ja se on muodostumisensa loppuvaiheessa. Se rauhoittuu pian, kun se siirtyy p\u00e4\u00e4sarjaan, joka on t\u00e4htien el\u00e4m\u00e4n aikuisvaihe.<\/p>\n

Toistaiseksi S106 IR pysyy emopilvess\u00e4\u00e4n, mutta se kapinoi sit\u00e4 vastaan. T\u00e4hdest\u00e4 irtoava aine ei ainoastaan anna pilvelle sen tiimalasin muotoa, vaan my\u00f6s kuumentaa ja levottomuuttaa sen sis\u00e4lt\u00e4m\u00e4\u00e4 vetykaasua. Sen muodostamat monimutkaiset kuviot n\u00e4kyv\u00e4t selv\u00e4sti t\u00e4ss\u00e4 Hubble-kuvassa.<\/p>\n

Nuori t\u00e4hti l\u00e4mmitt\u00e4\u00e4 my\u00f6s ymp\u00e4r\u00f6iv\u00e4\u00e4 kaasua, jolloin sen l\u00e4mp\u00f6tila nousee jopa 10 000 celsiusasteeseen! T\u00e4hden s\u00e4teily saa kaasun hehkumaan, mik\u00e4 n\u00e4kyy kuvassa sinisen\u00e4 alueena.<\/p>\n

N\u00e4it\u00e4 hehkuvan kaasun alueita erottaa toisistaan viile\u00e4mpi, paksu p\u00f6lykaistale, joka n\u00e4kyy punaisena. T\u00e4m\u00e4 tumma aine peitt\u00e4\u00e4 nuoren t\u00e4hden l\u00e4hes kokonaan n\u00e4kyvist\u00e4, mutta se n\u00e4kyy silti pilkottavan p\u00f6lykaistaleen leveimm\u00e4st\u00e4 kohdasta.<\/p>","protected":false},"excerpt":{"rendered":"
