Andromeda

Location of the Andromeda Galaxy (M31) in the Andromeda constellation.

Andromeda Galaxy (/ ændrɒmɪdə /), oo sidoo kale loo yaqaan Messier 31, M31, ama NGC 224, waa galax galax ku dhawaad ​​780 kiilo koron (2.5 malyuun oo iftiin) oo ka yimid Dunida, iyo galaxyadda ugu dhow ee Milky Way. ] Magaciisa wuxuu ka yimaadaa aagga cirka ee uu ka muuqanayo, kooxda isku xirta Andromeda. Sanadkii 2006 sawirada Spitzer Space Telescope ayaa shaaca ka qaaday in Andromeda Galaxy ay ka kooban tahay hal xiddig oo trillion ah, [10] in ka badan laba jeer tirada tirakoobka Milky Way ee qiyaastii 200-400 bilyan. Andromeda Galaxy, oo qiyaastii ku dhowaad 220,000 sanadood oo iftiin ah, waa galaxda ugu weyn ee kooxdayada Degaanka, kaas oo sidoo kale ku jira Goobta Saddexda Geeska ah iyo Galaxyada kale. Galaxy-ga ayaa lagu qiyaasay inuu yahay qiyaastii 1.76 jeer oo ka mid ah Sooshiyaalka Galaxy-ga (0.8-1.5 × 1012 oo ah qoraxda qorraxda ah [9] [10] vs milky Way 8.5 × 1011 qorraxda). Milkiilaha Milkyiga iyo Andromeda waxaa la rajeynayaa in ay ku dhacaan ~ 4,5 bilyan sanno, sameynta galax weyn oo weyn [14] ama galax weyn. Iyada oo muuqaal balaadhan oo ah 3.4, Andromeda Galaxy waa qaybta ugu quruxda badan ee walxaha Messier [16] - taas oo u muuqata in isha lagu arko habeenkii biloowday, [17] xitaa marka laga eego meelaha leh ifilada dhexdhexaadka ah

Iyada oo ku saleysan muuqaalka iftiinka muuqaalka ah, Andromeda Galaxy waxa loo aqoonsaday sida SA (s) b galaxiga ah ee nidaamka kala soocista ee Vaucouleurs-Sandage ee galaxies. Si kastaba ha ahaatee, xogta laga helay sahanka 2MASS waxay muujisay in Andromeda dhab ahaantii tahay galax galbeed, sida Milky Way, oo leh barxadda Andromeda ee ujeeda xagiisa dheer. [56] Sannadkii 2005, astronomers waxay isticmaaleen teleskoberka Keck si ay u muujiyaan in rucubka dufanka leh ee xiddigaha ka soo baxaya galaxu ay dhab ahaantii qayb ka tahay diskka laftiisa laftiisa. Tani waxay ka dhigan tahay in xiddigaha xiddigaha ee Galaxy ee ku yaala Andromeda Galaxy ay saddex jeer ka badan yihiin dhexroor sidii hore loogu qiyaasay. Tani waxay ka dhigan tahay caddayn in ay jirto qulqulo fara badan oo fara badan oo galbeedka ka dhigaya in ka badan 220,000 iftiin-sano (67,000 pc) dhexroor. Markii hore, qiyaastii cabbirka Galaxy Andromeda Galaxy wuxuu u dhexeeyay 70,000 ilaa 120,000 iftiin sano (21,000 ilaa 37,000 pc).
