Mufananidzo mutsva we James Webb Space Telescope inoburitsa nekujeka kukuru sumbu rePismis 24 mumoyo weinodanwa Lobster Nebula, nzvimbo iri pedyo yeMilky Way inoberekerwa nyeredzi huru. Pakutanga kuona inoita senge ridge yakavhenekerwa, asi ndizvo chaizvo guruva rakavezwa uye gasi nemwaranzi nemhepo kubva kunyeredzi dzichangobva kuumbwa.
Yakarekodhwa nekamera ye pedyo ne infrared NIRCam, chiitiko chinoratidza zviuru zvemavara akajeka uye runyararo rweorenji runoyeuchidza makomo. Izvo zvinoonekwa semhute pamusoro pepamusoro ndizvo zvifukidzo zvegasi neguruva iyo inoparadzira chiedza chenyeredzi, nepo bhendi rakatsvedzerera rematoni ocher richiyambuka chikamu chepamusoro chekurudyi chefuremu.
Pismis 24, inzvimbo yenyeredzi inoonekwa
Iyo cluster iri muScorpius, inenge Makore 5.500 echiedza, uye inotambira imwe yenzvimbo dzinoita nyeredzi padyo nePasi. Kunzwa kweWebb kunoibvumira kusiyanisa kwete nyeredzi chete musumbu, asiwo makumi ezviuru zvenyeredzi izvo zviri kumashure, mundege yeMilky Way, uye gadzira star mafoto yehukuru hwakadzama.
Pakati pechifananidzo pamire Pismis 24-1, nyeredzi iyo kwemakore yaifungidzirwa kuva yakasiyana uye yakakura zvikuru. Kumwe kunyatsotarisisa kunoratidza kuti isystem ine zvishoma zvikamu zviviri, vane ruzhinji rwakapoteredza 74 uye 66 nguva yeZuva, pakati pezvinopenya uye zvine simba zvinozivikanwa mugalaxy yedu, muenzaniso wakajeka we nyeredzi huru.
Nyeredzi dzakapenya kwazvo dzinoratidza mapeaks e diffraction ye zvitanhatu, siginicha yakajairika murudzi urwu rwechiridzwa chenyeredzi huru kwazvo. Mukupesana, mazana kana zviuru zvenhengo duku dzeboka racho dzinooneka mumimvuri michena, yeyero, uye mutsvuku, zvichienderana nerudzi rwadzo rwenyeredzi uye kuwanda kweguruva rakadzipoteredza.
Mhepo yepamusoro-soro pamadziro eorenji inonongedza kuboka repakati, uye hwaro hwaro hwaigona kubata mazana emagetsi ezuva Nezviyero zvakaenzana nekutenderera kweNeptune, mutsetse wacho unosvika 5,4 light-years, chiyero chinosimbisa ukuru hwezvivakwa izvi.
Zvinorehwa nemavara nezvimiro
Iyo palette yesainzi inoshandiswa inobatsira ku kududzira fizikisi yedunhu: iyo cyan toni inomiririra inopisa, ionized haidrojeni kufadzwa nemwaranzi kubva kunyeredzi huru; orenji inotsvaga guruva mamorekuru anoyeuchidza utsi; uye mavara matsvuku molecular hydrogen kunotonhora uye kwakaoma, uko nyeredzi itsva dzinoberekwa.
Nzvimbo dzakasviba dzinoratidza gasi rakanyanya kukora iro risingabvumidze chero mwenje kubuda, ukuwo kupenya kuchena kunoenderana ne. huruva uye gasi mukupararira. Pakati pezvikomo, pane makoramu-akaita sechigunwe uye filaments inonongedza kune kunobva radiation: kana yakamanikidzwa nekumanikidzwa nemhepo, matipi avo anogona. kudonha uye kuita nyeredzi mukati.
Kupisa mwaranzi inoveza nebula
Nyeredzi dzinopisa zvikuru, diki munzvimbo iyi — dzimwe dzine tembiricha dzinopeta kanoverengeka kupfuura dzeZuva — dzinoburitsa mhepo ine simba uye abrasive mwaranzi iyo inochera mhango mumadziro eruzha. Iri bubble rinowedzera kupfuura yeNIRCam yekuona, kunyangwe zvikamu zvinogona kuoneka pazasi uye kumusoro kurudyi kwemufananidzo.
Jets uye kumberi zvinogonawo kuonekwa. ionized gasi kuyerera kubva mumipata, uye masipire anoshamisa egasi rinopenya rinoramba kukukurwa. Mamorphologies akadaro, anoonekwa mune infrared zvakadzama, akakosha pakuvakazve kuti mhinduro kubva kunyeredzi huru dzinogadzirisa sei kuzvarwa kwezvizvarwa zvitsva yenyeredzi.
Observatory kuseri kwemufananidzo
Webhu ndiyo nzvimbo yekucherechedza de saizi yakakura uye simba yakatumirwa muchadenga, mhedzisiro yekubatana pakati peNASA, ESA, neCanadian Space Agency. Europe yakabatsira kutanga kuburikidza neAriane 5, kuvandudzwa kweiyo spectrograph NIRSpec uye hafu yeMIRI yepakati-infrared chiridzwa, yakagadzirwa mumubatanidzwa nevadyidzani vepasirese.
Yayo 6,5-mita yekutanga girazi, yakashongedzwa ne ndarama, uye shanu-layered sunshade saizi yedare retennis inobvumira kushanda patembiricha yakaderera zvakanyanya. Observatory iri pedyo Makiromita zviuru makumi maviri nemashanu kubva kuPasi, chinhambwe chinoita kuti kugadzirisa kwakananga kusagoneke, uye dhizaini yayo yakagadziridzwa kuti idzidze zvakasikwa mu infrared, kubva kumapuraneti madiki kusvika kune ekutanga. makwara enzou mushure meBig Bang.
Nemifananidzo yakaita sePismis 24, Webb inosimbisa basa rayo sechinhu chakakosha chekunzwisisa maumbirwo avanoita nekushanduka-shanduka nyeredzi huru kwazvo uye kuti zvakatenderedza gasi neguruva zvinoumbwa sei nesimba razvinoburitsa.
