Au trecut sute de ani de c\u00e2nd Cristofor Columb a navigat \u00een jurul P\u0103m\u00e2ntului, descoperind lumi noi \u2014 dar s\u0103 nu l\u0103sa\u021bi pe nimeni s\u0103 v\u0103 spun\u0103 c\u0103 Epoca Marilor Descoperiri s-a \u00eencheiat. Universul este vast \u0219i plin de mistere de dezv\u0103luit, precum lumea cometei 67P\/Churyumov-Gerasimenko, care este explorat\u0103 \u00een prezent de sonda spa\u021bial\u0103 Rosetta.<\/p>\n<\/div>\n

De c\u00e2nd a ajuns la comet\u0103 \u00een luna august a anului trecut, Rosetta a examinat peste dou\u0103 treimi din suprafa\u021ba cometei, iar rezultatele s-au dovedit mai interesante dec\u00e2t se a\u0219tepta. Peisajul este un amestec captivant, cu unele regiuni acoperite de un strat gros de praf, iar altele caracterizate de st\u00e2nci abrupte \u0219i canioane. Alte zone g\u0103zduiesc \u0219an\u021buri uria\u0219e, gropi \u0219i bolovani sau de\u0219erturi netede.<\/p>\n

Multe dintre versan\u021bii abrup\u021bi de pe Rosetta sunt acoperi\u021bi de cr\u0103p\u0103turi care par periculoase. Cea mai mare cr\u0103p\u0103tur\u0103 are 500 de metri lungime \u2013 adic\u0103 c\u00e2t cinci terenuri de fotbal!<\/p>\n

O alt\u0103 caracteristic\u0103 interesant\u0103 o reprezint\u0103 jeturile care au fost observate ie\u0219ind din gropile \u00eempr\u0103\u0219tiate pe suprafa\u021ba cometei. Gazul care iese din aceste jeturi ac\u021bioneaz\u0103 \u00eentr-un mod asem\u0103n\u0103tor v\u00e2ntului de pe P\u0103m\u00e2nt, mi\u0219c\u00e2nd praful de pe suprafa\u021b\u0103. Acest fenomen creeaz\u0103 uneori valuri pe suprafa\u021b\u0103, asem\u0103n\u0103toare celor pe care le vede\u021bi uneori pe plaj\u0103 c\u00e2nd se retrage valul.<\/p>\n

\u00cen cele c\u00e2teva luni de c\u00e2nd Rosetta c\u0103l\u0103tore\u0219te al\u0103turi de comet\u0103, am aflat deja foarte multe lucruri. Pe m\u0103sur\u0103 ce Rosetta va colecta tot mai multe date \u00een cursul anului urm\u0103tor, oamenii de \u0219tiin\u021b\u0103 sunt \u00eencrez\u0103tori c\u0103 vor putea r\u0103spunde \u00een sf\u00e2r\u0219it la c\u00e2teva \u00eentreb\u0103ri importante despre modul \u00een care s-a format Sistemul nostru Solar!<\/p>\n

Curiozitate:<\/b> O zi pe cometa lui Rosetta dureaz\u0103 jum\u0103tate dintr-o zi terestr\u0103, adic\u0103 doar 12 ore. \u00cens\u0103 \u00eei ia de \u0219ase ori mai mult timp dec\u00e2t P\u0103m\u00e2ntului s\u0103 fac\u0103 o rota\u021bie complet\u0103 \u00een jurul Soarelui.<\/p>","protected":false},"excerpt":{"rendered":"
