Astronomowie odkryli, \u017ce tak! Nazywamy je planetami pozas\u0142onecznymi, w skr\u00f3cie \u2013 egzoplanetami. Do tej pory odkryto ich tysi\u0105ce, a liczba ta b\u0119dzie rosn\u0105\u0107 w miar\u0119 kontynuowania poszukiwa\u0144.<\/p>\n<p>Bardzo trudno jest uzyska\u0107 rzeczywiste zdj\u0119cie egzoplanety, poniewa\u017c znajduj\u0105 si\u0119 one tak daleko.

Teraz potrzebujemy teleskopu, kt\u00f3ry specjalizuje si\u0119 w okre\u015blaniu wielko\u015bci egzoplanet. I tu w\u0142a\u015bnie pojawia si\u0119 CHEOPS!<\/p>\n<\/div>\n<p>Uruchomiona w grudniu 2019 roku misja CHEOPS \u2013 kt\u00f3rej pe\u0142na nazwa brzmi CHaracterising ExOPlanet Satellite \u2013 jest misj\u0105 ESA maj\u0105c\u0105 na celu poszerzenie naszej wiedzy na temat egzoplanet. Zamiast poszukiwa\u0107 nowych egzoplanet, CHEOPS b\u0119dzie bada\u0107 te, kt\u00f3re ju\u017c odkryli\u015bmy i dla kt\u00f3rych obliczono mas\u0119 planety.<\/p>\n<p>CHEOPS jest wyposa\u017cony w zaawansowany technologicznie i niezwykle czu\u0142y przyrz\u0105d zwany fotometrem, kt\u00f3ry mierzy nat\u0119\u017cenie \u015bwiat\u0142a.

Dzi\u0119ki temu naukowcy bior\u0105cy udzia\u0142 w misji b\u0119d\u0105 mogli obliczy\u0107 rozmiar egzoplanety! Po po\u0142\u0105czeniu tych informacji z danymi dotycz\u0105cymi masy mo\u017cliwe b\u0119dzie obliczenie g\u0119sto\u015bci planet pozas\u0142onecznych. Da to wskaz\u00f3wki co do tego, z czego sk\u0142adaj\u0105 si\u0119 te planety. Czy s\u0105 to \u015bwiaty skaliste, czy gazowe giganty?
