T\u00f6bb sz\u00e1z \u00e9v telt el az\u00f3ta, hogy Krist\u00f3f Kolumbusz k\u00f6rbehaj\u00f3zta a F\u00f6ldet \u00e9s \u00faj vil\u00e1gokat fedezett fel \u2014 de ne hagyd, hogy b\u00e1rki is azt mondja neked, hogy a felfedez\u00e9sek kora v\u00e9get \u00e9rt. Az Univerzum hatalmas \u00e9s tele van felfedez\u00e9sre v\u00e1r\u00f3 rejt\u00e9lyekkel, mint p\u00e9ld\u00e1ul a 67P\/Churymov-Gerasimenko \u00fcst\u00f6k\u00f6s vil\u00e1ga, amelyet jelenleg a Rosetta \u0171rszonda kutat.<\/p>\n<\/div>\n

A Rosetta tavaly augusztusban \u00e9rkezett meg a \u00fcst\u00f6k\u00f6sh\u00f6z, \u00e9s az\u00f3ta a felsz\u00edn t\u00f6bb mint k\u00e9tharmad\u00e1t vizsg\u00e1lta meg, ami a v\u00e1rtn\u00e1l is \u00e9rdekesebbnek bizonyult. A t\u00e1j izgalmas kever\u00e9k: egyes r\u00e9gi\u00f3kat vastag porr\u00e9teg bor\u00edt, m\u00e1sokat pedig szikl\u00e1s szikl\u00e1k \u00e9s kanyonok jellemeznek. M\u00e1s ter\u00fcleteken hatalmas \u00e1rkok, g\u00f6dr\u00f6k \u00e9s sziklat\u00f6mb\u00f6k, illetve sima sivatagok tal\u00e1lhat\u00f3k.<\/p>\n

A Rosetta sz\u00e1mos meredek sziklafal\u00e1t vesz\u00e9lyesnek t\u0171n\u0151 reped\u00e9sek bor\u00edtj\u00e1k. A legnagyobb reped\u00e9s 500 m\u00e9ter hossz\u00fa \u2013 ez olyan, mintha \u00f6t futballp\u00e1lya hossz\u00fas\u00e1g\u00fa lenne!<\/p>\n

Egy m\u00e1sik izgalmas jelens\u00e9g azok a g\u00e1zsugarak, amelyek a \u00fcst\u00f6k\u00f6s felsz\u00edn\u00e9n sz\u00e9tsz\u00f3rtan elhelyezked\u0151 m\u00e9lyed\u00e9sekb\u0151l t\u00f6rnek fel. Az ezekb\u0151l a g\u00e1zsugarakb\u00f3l kisz\u00f6k\u0151 g\u00e1z hasonl\u00f3an hat, mint a F\u00f6ld\u00f6n a sz\u00e9l: felkavarja a felsz\u00ednen l\u00e9v\u0151 port. Ez n\u00e9ha olyan hull\u00e1mokat hoz l\u00e9tre a felsz\u00ednen, mint amilyeneket n\u00e9ha a tengerparton l\u00e1thatunk, amikor a dag\u00e1ly visszah\u00faz\u00f3dik.<\/p>\n

Azokban a n\u00e9h\u00e1ny h\u00f3napokban, ami\u00f3ta a Rosetta a \u00fcst\u00f6k\u00f6s mellett halad, m\u00e1ris rengeteget tanultunk. Ahogy a Rosetta az elk\u00f6vetkez\u0151 \u00e9v sor\u00e1n egyre t\u00f6bb adatot gy\u0171jt, a tud\u00f3sok b\u00edznak abban, hogy v\u00e9gre v\u00e1laszt kaphatnak n\u00e9h\u00e1ny fontos k\u00e9rd\u00e9sre a Naprendszer\u00fcnk kialakul\u00e1s\u00e1val kapcsolatban!<\/p>\n

\u00c9rdekes t\u00e9ny:<\/b> A Rosetta-\u0171rsonda \u00e1ltal megk\u00f6zel\u00edtett \u00fcst\u00f6k\u00f6s\u00f6n egy nap fele olyan hossz\u00fa, mint egy f\u00f6ldi nap, vagyis mind\u00f6ssze 12 \u00f3ra. Azonban az \u00fcst\u00f6k\u00f6snek hatszor t\u00f6bb id\u0151be telik, mint a F\u00f6ldnek, hogy egyszer k\u00f6rbeforogjon a Nap k\u00f6r\u00fcl.<\/p>","protected":false},"excerpt":{"rendered":"
