Ilmaruumis on imelisi asju: on planeete oma kaaslastega, on t\u00e4hti, galaktikaid ja tolmupilvi, on musti auke ja tumedat ainetki.<\/p>\n

N\u00fc\u00fcd on astronoomid avastanud midagi, mida varem n\u00e4htud ei ole \u2014 suure laia tumeainepilve, milles leidub k\u00fcll rohkesti n\u00e4htavast ainest gaasi, kuid nii suure pilve kohta ennen\u00e4gematul kombel mitte ainsatki t\u00e4hte.<\/p>\n

Nii v\u00e4idavadki Alejandro Ben\u00edtez-Llambay Itaaliast Milano-Bicocca \u00dclikoolist ja ta kolleegid, et tegu on nii\u00f6elda luhta l\u00e4inud galaktikaga, millesuguseid on tegelikult arvatudki olemas olevat.<\/p>\n

Galaktikad, suured t\u00e4hekogumid nagu n\u00e4iteks meie Linnutee on praeguse arusaama j\u00e4rgi tekkinud umbes samasuguste hiigelsuurte tumeainepilvede asupaigus, kuhu tumeaine raskusv\u00e4lja abiga on kokku kogunenud suur hulk kosmilist gaasi, millest on hakanud tekkima t\u00e4hti.<\/p>\n

V\u00f5ib aga arvata, et m\u00f5nigi kord on v\u00f5inud juhtuda, et gaasi k\u00fcll koguneb, kuid siiski liiga v\u00e4he, et see hakkaks siin-seal veelgi tugevamalt kokku t\u00f5mbuma ja t\u00e4htedeks saama.<\/p>\n

<\/p>\n

N\u00fc\u00fcd avastatud pilv, millele teadlased on nimeks pannud Pilv-9 ehk Cloud-9, on t\u00f5en\u00e4oliselt just \u00fcks niisuguseid luhtunud galaktikaid.<\/p>\n

Pilve nimi v\u00f5ib tunduda keelem\u00e4nguline ja viitavat ingliskeelse s\u00f5na\u00fchendina suurele \u00f5nnetundele ja k\u00f5rgendatud meeleolule, kuid tegu on lihtsalt \u00fcheksanda gaasipilvega, mille astronoomid on spiraalgalaktika M94 l\u00e4histelt leidnud.<\/p>\n

Pilve vaadeldi Hubble’i kosmoseteleskoobiga. Maapealsete teleskoopidega vaadelduna v\u00f5inuks seda pidada ka eriti tuhmiks k\u00e4\u00e4busgalaktikaks, kuid Hubble v\u00f5imaldas t\u00e4htede olemasolu pilves kindlalt v\u00e4listada.<\/p>\n

Pilv-9 asub meist umbes 16 miljoni valgusaasta kaugusel. Selle l\u00e4bim\u00f5\u00f5t on ligi 5000 valgusaastat. Seal leidub vesinikku umbes miljoni P\u00e4ikese massi jagu, kuid tumeainet tundub seal olevat m\u00e4rksa rohkem, umbes viis miljardit P\u00e4ikese massi.<\/p>\n

Ben\u00edtez-Llambay ja kaasautorid t\u00e4hendavad ajakirjas Astrophysical Journal Letters<\/a>, et samasuguseid nurjunud galaktikaid on maailmaruumis t\u00f5en\u00e4oliselt p\u00e4ris rohkesti.<\/p>\n

Avastus aitab loodetavasti muu hulgas paremini m\u00f5ista nii galaktikate teket kui ka tumeda aine olemust.<\/p>\n

Pildil on t\u00e4histatud Pilv-9 asukoht.<\/p>\n
