Pfupisa nyaya yacho:  Chero chingave chakakonzera kuti matombo maduku okudenga aungane pamwe chete mabhiriyoni amakore akapfuura, simba remagineti harisi iro rinogona kuva chikonzero. Masayendisiti azivisa nhasi kuti kuyerwa kwakaitwa neEuropean space probe Philae, iyo yakamhara pa comet 67P muna November, inoratidza kuti musimboti wekometi hauna magineti. Vamwe vanodzidza nezvezvinhu zviri muchadenga vakafunga kuti simba remagineti ringave rakaita kuti matombo arambe akaenzana obva asungwa pamwe chete kuti ave matombo makuru mumatanho okutanga okuumbwa kwemapuraneti. Mufananidzo wakaumbwa nemifananidzo 18 inoratidza chiitiko chekometi 67P/Churyumov-Gerasimenko kubva pamakona akasiyana-siyana sezvinoonekwa pakati pa 31 January (kumusoro kuruboshwe) na 25 March (pasi kurudyi), apo nzvimbo yacho yakanga iri kure nemakiromita anenge 30 kusvika ku100 kubva pakometi. Asi mupepa rakabudiswa paIndaneti nemagazini inonzi Science, boka rinotungamirirwa naHans-Ulrich Auster paTechnical University of Braunschweig, kuGermany, rakati mashoko avo - ayo akabatsirwa nokudzoka katatu kusingatarisirwi kwakabvumira Philae kuunganidza migumisiro yakawanda kupfuura yakanga yakarongwa - haatsigiri pfungwa iyi. 'Kudai pasi raiva nemagineti, taizotarisira kuona kuwedzera kuri pachena mukuverenga kwemagineti sezvo taiswedera pedyo nepasi,' akadaro Auster. 'Kana kometi 67P/Churyumov-Gerasimenko iri mumiririri wenyukireya dzose dzemakometi, ipapo tinokarakadza kuti masimba emagineti haasati achizotongoita basa mukuunganidzwa kwezvinhu zvokuvakisa zvepasi zvinopfuura mita imwe muhukuru.' Allan H. Treiman, musayendisiti mukuru weLunar and Planetary Institute muHouston, Texas, uyo akanga asina kubatanidzwa munzvero yacho, akati miuyo yacho nenzira ine musoro inoratidzira kuti mamwe masimba akanga ane mhaka. Magnetic data pamberi (kumusoro) uye mushure (pasi) kwekurovera kwechikepe pakati pekutanga neyechipiri touchdowns. Kureba pamusoro pechiso kunoratidzwa pa x-axis uye simba remagineti pamunda pa y-axis. Kuyerwa (michinjiko) kunoenzaniswa nemuenzaniso wekufungidzira (mutsetse wakasimba) uchifungidzira nzvimbo ine magineti zvishoma.
Vaifunga kuti simba remagineti ndiro raiita kuti matombo arambe akabatana. Izvi zvingave zvakatungamirira kumatanho apakuvamba okuumbwa kwenyika, vakadaro masayendisiti. Zvakawanikwa neRosetta hazvitsigiri pfungwa yacho sezvo mwoyo we67P usina magineti.
