Dans un premier temps, Kepler a observé une même région du ciel pendant quatre ans, à l’affût d’ombres : l’infime baisse de luminosité d’une étoile lorsqu’une planète passe devant elle. Le champ de vision de Kepler contenait plus de 150,000 étoiles, et le télescope a observé des milliers de ces ombres, appelées transits.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eLe télescope a perdu une grande partie de sa capacité de pointage en 2013 et a rapidement entamé sa seconde mission, baptisée K2. Dans le cadre de K2, Kepler observait des étoiles situées dans le plan orbital des planètes de notre système solaire et changeait plus souvent de champ de vision. L’engin spatial a continué à découvrir de nouvelles planètes autour d’autres étoiles, ou exoplanètes, jusqu’à son retrait du service en 2018, après épuisement de son carburant. Kepler détient le record du nombre de planètes découvertes par une mission de recherche d’exoplanètes : plus de 2,600. Kepler a révolutionné l’étude des exoplanètes, nous révélant une diversité bien plus fascinante que nous ne l’imaginions.\u003cbr\u003e\u003cbr\u003eCrédit : NASA\/JPL-Caltech\u003c\/p\u003e\n\u003cp\u003eDécouvrez toute la série : \u003ca href=\"https:\/\/astrography.com\/collections\/space-telescopes\"\u003e\u003cstrong\u003eTélescopes spatiaux\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003e\u003cbr\u003e\u003c\/h2\u003e","brand":"NASA","offers":[{"title":"Poster (semi-brillant) \/ S - 40 x 30cm","offer_id":54390750708036,"sku":"Poster-40x30cm","price":108.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ M - 50 x 40cm","offer_id":54390750740804,"sku":"Poster-50x40cm","price":137.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ L -  70 x 50cm","offer_id":54390750773572,"sku":"Poster-70x50cm","price":163.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ XL - 100 x 70cm","offer_id":54390750806340,"sku":"Poster-100x70cm","price":248.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ XXL - 140 x 100cm","offer_id":54390750839108,"sku":"Poster-140x100cm","price":415.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ S - 16\" x 12\"","offer_id":54390750871876,"sku":"Poster-16x12in","price":108.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ M - 20\" x 16\"","offer_id":54390750904644,"sku":"Poster-20x16in","price":137.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ L - 28\" x 20\"","offer_id":54390750937412,"sku":"Poster-28x20in","price":163.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ XL - 40\" x 28\"","offer_id":54390750970180,"sku":"Poster-40x28in","price":248.0,"currency_code":"PLN","in_stock":true},{"title":"Poster (semi-brillant) \/ XXL - 55\" x 40\"","offer_id":54390751002948,"sku":"Poster-56x40in","price":415.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ S - 40 x 30cm","offer_id":54390751035716,"sku":"FineArt-40x30cm","price":163.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ M - 50 x 40cm","offer_id":54390751068484,"sku":"FineArt-50x40cm","price":193.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ L -  70 x 50cm","offer_id":54390751101252,"sku":"FineArt-70x50cm","price":248.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ XL - 100 x 70cm","offer_id":54390751134020,"sku":"FineArt-100x70cm","price":359.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ XXL - 140 x 100cm","offer_id":54390751166788,"sku":"FineArt-140x100cm","price":552.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ S - 16\" x 12\"","offer_id":54390751199556,"sku":"FineArt-16x12in","price":163.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ M - 20\" x 16\"","offer_id":54390751232324,"sku":"FineArt-20x16in","price":193.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ L - 28\" x 20\"","offer_id":54390751265092,"sku":"FineArt-28x20in","price":248.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ XL - 40\" x 28\"","offer_id":54390751297860,"sku":"FineArt-40x28in","price":359.0,"currency_code":"PLN","in_stock":true},{"title":"Fine Art (mat) \/ XXL - 55\" x 40\"","offer_id":54390751330628,"sku":"FineArt-55x40in","price":552.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/2862\/0473\/files\/kepler-space-telescope-1_Thumbnail_Poster.webp?v=1693751687","url":"https:\/\/astrography.com\/fr-pl\/products\/kepler-space-telescope","provider":"Astrography","version":"1.0","type":"link"}
