Vesolje je ogromno in polno skrivnosti, ki jih je treba odkriti, kot je na primer svet kometa 67P\/\u010curimov-Gerasimenko, ki ga trenutno raziskuje vesoljska sonda Rosetta.<\/p>\n<\/div>\n<p>Odkar je sonda Rosetta avgusta lani prispela k kometu, je preu\u010dila ve\u010d kot dve tretjini njegove povr\u0161ine, ki se je izkazala za zanimivej\u0161o, kot se je pri\u010dakovalo. Pokrajina je razburljiva me\u0161anica, saj so nekatere regije prekrite z gostim prahom, druge pa zaznamujejo skalnate pe\u010dine in kanjoni. Na drugih obmo\u010djih pa najdemo ogromne jarke, jame in balvane ali gladke pu\u0161\u010dave.<\/p>\n<p>Mnoge strme pe\u010dine na Rosetti so prekrite z razpokami, ki izgledajo nevarno. Najve\u010dja razpoka je dolga 500 metrov \u2013 to je toliko kot pet nogometnih igri\u0161\u010d!<\/p>\n<p>\u0160e ena zanimiva zna\u010dilnost so curki, ki so jih opazili, kako se dvigajo iz jam, razpr\u0161enih po povr\u0161ini kometa. Plin, ki uhaja iz teh curkov, deluje podobno kot veter na Zemlji in po povr\u0161ini premika prah. To v\u010dasih ustvarja valove po povr\u0161ini, podobne tistim, ki jih v\u010dasih vidimo na pla\u017ei, ko se plima umika.<\/p>\n<p>V teh nekaj mesecih, odkar Rosetta potuje ob kometu, smo se \u017ee ogromno nau\u010dili. Ker bo Rosetta v naslednjem letu zbrala \u0161e ve\u010d podatkov, so znanstveniki prepri\u010dani, da bodo kon\u010dno lahko odgovorili na nekatera pomembna vpra\u0161anja o nastanku na\u0161ega Oson\u010dja!<\/p>\n<p><b>Zanimiv podatek:<\/b> Dan na kometu Rosetta traja polovico zemeljskega dneva, torej le 12 ur. Vendar pa za en obhod okoli Sonca potrebuje 6-krat ve\u010d \u010dasa kot Zemlja.<\/p>","protected":false},"excerpt":{"rendered":"<p>It\u2019s been hundreds of years since Christopher Columbus sailed the Earth discovering new worlds \u2014 but don\u2019t let anyone tell you that the Age of Exploration is over.
