Ti najsodobnej\u0161i vesoljski observatoriji, podobni \u010dasovnim strojem 21. stoletja, bodo pogledali v preteklost in znanstvenikom pomagali razvozlati skrivnosti nastanka zvezd, galaksij in samega vesolja.<\/p>\n<\/div>\n<p>Herschel bo najve\u010dji teleskop, ki je bil kdajkoli izstreljen v vesolje. Njegovo srce predstavlja 3,5 m \u0161iroko glavno zrcalo \u2013 ki je precej ve\u010dje, a la\u017eje od zrcala, ki ga uporablja vesoljski teleskop Hubble. 3,4-tonski observatorij je poimenovan po nem\u0161ko-britanskem astronomu Williamu Herschelu, ki je leta 1800 zapisal zgodovino z odkritjem nevidne infrarde\u010de svetlobe (ki jo ob\u010dutimo kot toploto). Trije instrumenti na sodobnem teleskopu Herschel bodo vsaj tri leta raziskovali oblake hladnega prahu, kjer nastajajo zvezde, ter oddaljene galaksije, ki mo\u010dno sijajo v infrarde\u010dem spektru.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2068\" data-credit=\"ESA\/Thales\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2009\/03\/Planck_telescope2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2009\/03\/planck_telescope2\/17872743-2-eng-GB\/Planck_telescope.jpg\" alt=\"Planck telescope\"><figcaption>Planckov teleskop<\/figcaption><\/figure>\n<p>Poleg satelitov Herschel bo v vesolju tudi satelit, ki je zasnovan za opazovanje za\u010detkov \u010dasa.

Da bi lahko zaznali in kartirali to nevidno mikrovalovno sevanje, bo treba Planckovih dveh detektorjev ohladiti na -273 stopinj Celzija.
