Z Ziemi czasami mo\u017cemy dostrzec Wenus i Merkurego jako czarne plamki przemieszczaj\u0105ce si\u0119 przed tarcz\u0105 S\u0142o\u0144ca. Podczas takich zjawisk \u2013 zwanych tranzytami \u2013 planeta zas\u0142ania niewielk\u0105 cz\u0119\u015b\u0107 \u015bwiat\u0142a, przez co S\u0142o\u0144ce wydaje si\u0119 nieco s\u0142abiej \u015bwieci\u0107. Podobne zjawiska przyciemnienia mog\u0105 by\u0107 spowodowane przez egzoplanety \u2013 \u015bwiaty kr\u0105\u017c\u0105ce wok\u00f3\u0142 bardziej odleg\u0142ych gwiazd. Teraz ESA postanowi\u0142a opracowa\u0107 now\u0105 misj\u0119 naukow\u0105 maj\u0105c\u0105 na celu poszukiwanie tych tranzyt\u00f3w.<\/p>\n<\/div>\n

Misja znana pod nazw\u0105 CHEOPS (skr\u00f3t od CHaracterising ExOPlanets Satellite) ma zosta\u0107 rozpocz\u0119ta w 2017 roku. Jej celem b\u0119d\u0105 jasne, pobliskie gwiazdy, o kt\u00f3rych wiadomo ju\u017c, \u017ce kr\u0105\u017c\u0105 wok\u00f3\u0142 nich planety. Sonda b\u0119dzie z du\u017c\u0105 precyzj\u0105 monitorowa\u0107 jasno\u015b\u0107 ka\u017cdej z gwiazd, poszukuj\u0105c charakterystycznych oznak tranzytu.<\/p>\n

Szczeg\u00f3\u0142owa analiza zmian w padaj\u0105cym \u015bwietle gwiazd pozwoli na bardzo dok\u0142adny pomiar \u015brednicy ka\u017cdej z planet przechodz\u0105cych przed gwiazd\u0105. W przypadku planet o znanej masie mo\u017cliwe b\u0119dzie obliczenie ich g\u0119sto\u015bci, co dostarczy wskaz\u00f3wek dotycz\u0105cych ich budowy wewn\u0119trznej.<\/p>\n

Znajomo\u015b\u0107 rozmiar\u00f3w i mas egzoplanet pomo\u017ce naukowcom zrozumie\u0107 proces powstawania planet o masie od kilkukrotnej masy Ziemi \u2013 tzw. \u2019superziemi\u2018 \u2013 a\u017c po \u015bwiaty wielko\u015bci Neptuna. Pozwoli to r\u00f3wnie\u017c zidentyfikowa\u0107 planety posiadaj\u0105ce rozleg\u0142e atmosfery, kt\u00f3re b\u0119d\u0105 idealnymi obiektami do bardziej szczeg\u00f3\u0142owych bada\u0144 przy u\u017cyciu teleskop\u00f3w nowej generacji. Nale\u017c\u0105 do nich naziemny Europejski Teleskop Bardzo Du\u017cy (European Extremely Large Telescope) oraz Kosmiczny Teleskop Jamesa Webba.<\/p>\n

Satelita CHEOPS jest opracowywany przez ESA i Szwajcari\u0119, przy udziale niekt\u00f3rych innych pa\u0144stw cz\u0142onkowskich ESA. Satelita b\u0119dzie kr\u0105\u017cy\u0142 po orbicie prawie polarnej, na wysoko\u015bci oko\u0142o 800 km nad Ziemi\u0105, a jego okres eksploatacji wyniesie 3 i p\u00f3\u0142 roku.<\/p>","protected":false},"excerpt":{"rendered":"
