Upphittat: Ett nytt kosmiskt objekt<\/h2>\n\n\n\n

En bra b\u00f6rjan p\u00e5 det nya \u00e5ret \u00e4r att ett forskarteam har hittat en helt ny typ av astronomiska objekt: ett stj\u00e4rnl\u00f6st, gasrikt, m\u00f6rk materia-rikt moln som ses som en relik fr\u00e5n tidigt galaxskapande.<\/p>\n\n\n\n

Molnet kallas Cloud-9 eller mera tungt Reionization-Limited H I Cloud eller “RELHIC” best\u00e5r av neutralt v\u00e4te och \u00e4r verkligen ett moln fr\u00e5n universums allra tidigaste skede. Just detta moln \u00e4r mera sf\u00e4riskt \u00e4n andra liknande formationer. Molnet ligger i n\u00e4rheten av galaxen M94 och tycks v\u00e4xelverka med galaxen. Cloud-9 har samma r\u00f6df\u00f6rskjutning som M94 och befinner sig d\u00e4rf\u00f6r p\u00e5 samma avst\u00e5nd, \u223c4.4 Mpc.<\/p>\n\n\n\n

I pressrelisen fr\u00e5n ESA\/Hubble <\/a>ber\u00e4ttas att molnet \u00e4r 4900 ljus\u00e5r i diameter och att v\u00e4tets massa motsvarar ungef\u00e4r 1 miljoner ggr solens. Till molnets “ekvation” h\u00f6r n\u00e4rvaron av m\u00f6rk materia motsvarande ca 5 miljarder solmassor. <\/p>\n\n\n\n

Uppt\u00e4ckten \u00e4r ett resultat av ett stort internationellt samarbete senaste \u00e5r (500-metersradioteleskopet i Kina, Green Bank, amerikanska VLA). Med Hubble-teleskopet kunde bekr\u00e4ftas att molnet, en galax som aldrig bildades men kanske blir till n\u00e5n g\u00e5ng i en avl\u00e4gsen framtid, inte inneh\u00e5ller n\u00e5gra stj\u00e4rnor. <\/p>\n\n\n\n
