On m\u00f6\u00f6dunud sadu aastaid sellest, kui Kristoffer Kolumbus purjetas \u00fcmber maailma ja avastas uusi maailmu \u2013 kuid \u00e4rge laske kellelgi endale \u00f6elda, et avastusajastu on m\u00f6\u00f6das. Universum on tohutu ja t\u00e4is avastamist ootavaid saladusi, nagu n\u00e4iteks komeet 67P\/Churyumov-Gerasimenko, mida praegu uurib kosmoselaev Rosetta.<\/p>\n<\/div>\n

Alates eelmise aasta augustist, mil Rosetta j\u00f5udis komeedi juurde, on ta uurinud \u00fcle kahe kolmandiku komeedi pinnast ning see on osutunud oodatust huvitavamaks. Maastik on p\u00f5nev segu: m\u00f5ned piirkonnad on kaetud paksu tolmuga, teised aga iseloomustavad kaljused kliimud ja kanjonid. Teistes piirkondades leidub hiiglaslikke kraave, auke ja r\u00e4ndrahne v\u00f5i siledaid k\u00f5rbealasid.<\/p>\n

Paljud Rosetta j\u00e4rsud kaljuseinad on kaetud ohtlikult n\u00e4ivate pragudega. Suurim pragu on 500 meetrit pikk \u2013 see on umbes viie jalgpalliv\u00e4ljaku pikkune!<\/p>\n

Veel \u00fcks p\u00f5nev n\u00e4htus on joad, mida on t\u00e4heldatud t\u00f5usmas komeedi pinnale laiali pillutatud s\u00fcvenditest. Nendest joadest v\u00e4ljuv gaas toimib veidi nagu tuul Maal, liigutades tolmu pinnal ringi. See tekitab m\u00f5nikord pinnale laineid, nagu neid, mida v\u00f5ib vahel n\u00e4ha rannas, kui t\u00f5usulaine taandub.<\/p>\n

Nende m\u00f5ne kuu jooksul, mil Rosetta on komeedi k\u00f5rval lennanud, oleme juba nii palju \u00f5ppinud. Kuna Rosetta kogub j\u00e4rgmise aasta jooksul \u00fcha rohkem andmeid, on teadlased veendunud, et suudavad l\u00f5puks vastata m\u00f5nele olulisele k\u00fcsimusele meie P\u00e4ikeses\u00fcsteemi tekke kohta!<\/p>\n

Huvitav fakt:<\/b> P\u00e4ev Rosetta komeedil kestab poole nii kaua kui Maa p\u00e4ev, vaid 12 tundi. Kuid \u00fche tiiru tegemine \u00fcmber P\u00e4ikese v\u00f5tab tal 6 korda kauem aega kui Maal.<\/p>","protected":false},"excerpt":{"rendered":"
