Hubble Sees deewaa in Serpens

By

Tani cusub image NASA / ESA Hubble Space xoqad muujinaysaa Galaxy qurux badan loogu aarayo loo yaqaan PGC 54493, oo ku yaalla shir tagayso ee Serpens (Abeesadii). Galaxy Tani waa qayb ka mid ah cluster Galaxy ah oo uu soo bartay by cirbixiyeyaasha sahaminta arrin xiiso yaqaan lensing gravitational daciif ah.

Saamayn Tani, keena qaybinta si aan loo sineyn ee arrinta (oo ay ku jirto arrinta madow) Caalamka oo dhan, ayaa inta laga hubsanayo via sahan sida ay Hubble Dhexdhexaad Deep Survey. Arrinta Dark waa mid ka mid ah waxyaalaha qarsoon weyn ee cosmology. Waxay u dhaqmo si kala duwan uu ka soo arrinta caadiga ah sida aysan u bixiya ama nuugo iftiin ama noocyada kale ee tamarta electromagnetic - sidaa muddada “madow.”

Waxaan Inkasta oo aan si toos ah u arki karaan arrin mugdi ah, waxaan ognahay waxa ka jira. Mid ka mid ah xabbad wax garadka cadayn u ah jiritaanka arintan dahsoon loo yaqaanaa “Dhibaatada warejin Galaxy.” Galaxies isku shaandheyn xawaare sida iyo hab in arrin caadi ah oo keliya sida - alaabtii aan u arko - ma noqon doono in ay iyagii ku soo wada qaban karo. Inta ay mass in uu yahay “seegay” muuqata waa arrin mugdi ah, taas oo la rumeysan yahay ilaa sameeyo qaar ka mid ah 27 boqolkiiba oo ka mid ah waxyaabaha guud ee Caalamka, tamarta madow iyo arrin caadi ah ka dhigaan ilaa inta ka hartay. PGC 55493 ayaa lagu soo bartay oo xidhiidh la leh saamayn loo yaqaan adhijirrada runtan. Tani waa dhaqan lensing daciif ah gravitational in abuuraa dhabtii yaryar oo ku yaala images of galaxies fog.

Hubble Fiirinta Light iyo madow ee caalamka

Tani cusub image NASA / ESA Hubble Space xoqad muujinaysaa kala duwan ee dalka Switzerland oo ifafaale runtan.

Meersan yihiin xiddigaha dhalaalaya, dhinaca dhexe sare ee jir aan u arko a object boosaska dhalinyarada yar yar (YSO) Yaqaano J033038.2 SSTC2D 303212. Ku yaalla shir tagayso ee Perseus, Xiddiga tani waa in marxaladaha hore ee ay nolosha iyo weli waxaa sameynta galay xidiga si buuxda u koray. In view this ka Hubble ee Camera Advanced Baadhitaanada(Taladadii) waxay u muuqataa in ay meesha qiiqu ka dhoobo ah ee wax dibadda iyo hoos kaas oo, dajisay dilaacmo dhalaalaya oo gaas ah dal ka xidiga laftiisa. Xiddiga kooxda yar yare e Tan waxaa dhab ku hareereysan disk ifaya ee ay socdeen warar ee ku wareegsan waxyaabaha sida foomamka - disc ah in aan arko gees-ka noogu muuqato.

Si kastaba ha ahaatee, this saxarka yar dhalaalaya waxaa dwarfed by ay deris runtan dhinaca hoose ee ku yiilleen, xawaare ah dhalaalaya, socdeen warar gaaska wispy xeeran sida ay u muuqato in qubmaysa wax mugdi ah ka soo galay meel. Daruur dhalaalaysa waa nebula eegida waxaa loo yaqaan a [B77] 63, daruur oo gaas ah interstellar oo la turjumayaan iftiin ka xiddigaha gundhig ay gudahood. Waxa jira tiro ka mid ah xiddigaha dhalaalaya gudahood [B77] 63, inta badan gaar ahaan xiddiga LkHA emission-line ee 326, oo deris dhow LZK 18.

Xiddigaha Kuwani ayaa la huriyo gaaska ku xeeran oo ay farshaxan galay qaabka wispy arkay in image this. Si kastaba ha ahaatee, u muuqataa qaybta ugu weyn ee image ay u noqon il madow qiiq cuskaday dibadda ka [B77] 63 iyo xiddigaha ay - nebula mugdi ah lagu magacaabo Dobashi 4173. Nebulae Dark waa daruuraha cajiib ah oo cufan oo ah wax garoonka-madow in daah ah jaamaha samada wuxuu iyaga gadaal ka, u muuqda abuuro luxay weyn iyo doodiisa eerily madhan cirka. Laacibiinta Kuwa dhibicyada lahu waxay sare ee ku degto, xad-dhaaf ah taasi run ahaantii been noo iyo Dobashi u dhexeeya 4173.

Supernovaer lagu arkay Laba Lights

By

Natiijada burbur ah qarax supernovaer xoog badan naftooda u muujiyo in boorish ah oo xasaasi ah oo iftiin infrared X-ray iyo, sida aan ka arki image this ka NASA ee Spitzer Space xoqad iyo Chandra X-Ray-socoshada, iyo Space Agency Yurub ee XMM-Newton.

Daruurtii shekaynaysay waa ruxruxo naxdin joogto ahayn, ee supernovaer ah in la soo goobjoog ka lahayd on Earth 3,700 sano ka hor. Laftiisa ayaa hadhay, loo yaqaan Puppis A, waa ku xeeran 7,000 sano oo iftiin ah iska, iyo ruxruxo lama filaan ah ku saabsan yahay 10 iftiin-sano guud ahaan.

Midabo pastel ee image tani caddaynaysaa in dhismeedka infrared X-ray oo midba midka kale loo raad raaco si dhow ula. Dhaska diirran ayaa ka mas'uul ah inta badan wavelengths iftiin infrared, xilsaaray midabada casaanka iyo cagaarka ah ee view this. Waxyaabaha kululeeya ruxruxo naxdin supernovaer ee shanqarta X-rays, kuwaas oo midab buluug. Gobollada halkaas oo qiiqa infrared X-ray iyo boorish wada qaadan on baxaya, metrik pastel more.

Ruxruxo lama filaan ah ayaa u muuqda in uu iftiimin sidii ay Hadaladii galay daruuraha ku hareereysan ee siigada iyo gaaska in buuxi meesha bannaan ee interstellar ee gobolka this.

Laga soo bilaabo ladooran ee infrared, cirbixiyeyaasha helay tirada guud ee siigada ee gobolka ka siman yihiin in ay ku saabsan rubuc ka mid ah baaxada leh ee naga qorraxda. Xog laga soo ururiyey Spitzer ee spectrograph infrared daaha ka sida ruxruxo naxdin la jabiyay marka laga reebo ugu miraha siigada nugul in ay buuxiyaan meel ku xeeran.

Qaraxyo supernovaer loo hirgaliyo waxyaabaha culus oo siin kara wax xumu ka jiilalka mustaqbalka ee xiddigaha iyo meerayaasha dhiso doono. Barashada sida supernovaer hadhaagii ballaariyo galay Galaxy oo la macaamilaan qalab kale oo ay bixisaa furayaasha muhiim galay asal ahaan naga gaar ah.
Xog infrared ka Spitzer ee multiband photometer imaging (MIPS) at wavelengths ah 24 iyo 70 microns waxaa loo qabtay in cagaaran iyo casaan. Xog X-ray ka XMM-Newton bilaabanaya kala duwan tamarta ee ah 0.3 si ay u 8 volts kiloelectron waxaa lagu muujiyey in buluug.
