Boka revazivi venyeredzi pasi pechirongwa cheMassachusetts Institute of Technology rakabudiswa , umo akazivisa kubudirira kwekupedzisira kwechinangwa chitsva chekutsvaga mapuraneti kunze kwesolar system. Transiting Exoplanet Survey Satellite (TESS) orbital telescope, Musi waKubvumbi 18, 2018, akawana chinhu chidiki pane zvese muchinangwa chake chetsvakiridzo - pamwe ipuraneti ine matombo saizi yePasi redu.
Iyo exoplanet HD 21749c inotenderera nyeredzi HD 8 nenguva yemazuva 21749. Iyo HD 21749 system iri makore makumi mashanu nematatu echiedza kubva kwatiri. Nyeredzi inobata 53% yehuremu hweZuva. Kutenderera kwepasi kupfupi kutenderedza nyeredzi yekumba kunoreva kuti tembiricha yepasi inogona kudarika 80 degrees Celsius. Mukunzwisisa kwedu, hupenyu padombo rinopisa zvakadaro hazvibviri. Asi izvi hazvikanganisi kubudirira kweTESS. Tekinoroji dzekutsvaga uye maturusi anozogadzira, uye vanoongorora nyeredzi vanotarisira kuwana akawanda exoplanets munzvimbo inogadzika kubva pakuona kwehupenyu hwepasi.
Zvinofanira kutaurwa kuti Kepler orbital telescope yakawana 2662 exoplanets mumakore ayo akawanda ekushanda, mazhinji ayo angave saizi yePasi. Chinangwa cheTESS chakasiyana. Teresikopu yeTESS inodzidza nyeredzi dziri pedyo uye, pamwe chete nemidziyo yakavakirwa pasi muChile (Planet Finder Spectrograph, PFS), inoita kuti zvikwanise kuona huwandu uye kunyangwe kuumbwa kwemhepo yeexoplanets nehumwe dhigirii rechokwadi.
Kwemakore maviri, iyo TESS mishoni inotarisira kudzidza pamusoro pe200 nyeredzi masisitimu. Masayendisiti anotarisira kuti izvi zvichabatsira kuwana anopfuura makumi mashanu exoplanets. Satellite inovhara pamusoro pe000% yedenga mukati memazuva gumi nematanhatu. Nenzira, imwe exoplanet yakawanikwa muHD 50 system - HD 90b. Asi mutumbi wekudenga uyu ndewe "sub-Neptune" kirasi, uye TESS yakatowana zvinhu zvakati wandei zvakadaro.
