Andromeda - Wiliau Hōkū hea ka mea me ka nō hoʻi. Hookui hookahe koko ana o ke nō hoʻi a me Andromeda

Andromeda - Wiliau Hōkū, iʻikeʻia me M31 a me NGC224. Kēia helical ho okumu Aia ma ka mamao o kahi o 780 kp (2,5 miliona malamalama-makahiki) mai Honua.

Andromeda - Wiliau Hōkū hea ka mea me ka nō hoʻi. Au i ka inoa o ia i loko o ka hanohano o ka mythical Alii. Loina i ka 2006 alakai aku i ka hopena e loaʻa mea e pili ana i kekahi trillion hoku - i ka liʻiliʻi mau manawa ma luna ma mua i loko o ka nō hoʻi, ma ka mea e, eia ma kahi o 200 -. 400 ieeeea?ʻepekema, i ka hookui ana o ka nō hoʻi, a me ka Andromeda Wiliau Hōkū e hiki mai ana ma kahi o 3, 75 ieeeea makahiki kahiko, a me ka hope kanaka nunui elliptical ole hoʻopoepoe Wiliau Hōkū e e hana. Akā, ma hope ma keia. aʻo mua, "i ka mythical Princess" nana e like.

Ka huahelu hōʻike i ka Andromeda. Ke Wiliau Hōkū i ka uliuli, a keʻokeʻo kaula. Ka mea i hana i kekahi komolima a puni ia, a harboring wela glowing nunui hoku. Dark uliuli-oho ka hahau ana Akä naÿe ia e ku e ia i ke kāʻei kua o ka aahu apo, a hōʻike i nā wahi ma kahi anuanu ao cocoons o ka hoku ho okumu ua pono e hoomaka ana. I ka nānā ana ma ka hiki hapa o ka pae ana o ke apo o Andromeda mea hou like eʻoni iho i na mea kaua. Ma ka ultraviolet huahelu mau me ka ho okumu e hoohalike ai ke komo lima o nā hale. Ka mea, i mua loaa e NASA telescope. Astronomers manaʻo i kēia mau apo, he hoike o ke kahua o galaxies ma ka hookui ana me ka oi ma mua o 200 miliona makahiki kokoke aku nei.

Na ukali o Andromeda

Like pono me ka nō hoʻi, Andromeda i ka helu o dwarf ukali, 14 o i i mua i loaa. The loa kaulana - M32 a me M110. O ka holo ana, ia mea olelo lealea i na hoku kēlā me kēia Wiliau Hōkū collide i kekahi i kekahi, e like me ka mamao mea nui loa ma waena o lākou. Ka nui, e hoike ana i ka ia, e hiki mai ma ka ike maopopo, kńnaka i nō lā vague manaʻo. Akā, ua invented inoa no ka wā e hiki mai keiki. Mlekomeda - no laila i Ka ÿaÿole läua i hänau kanaka nunui Wiliau Hōkūʻepekema.

clashes hoku

Andromeda - Wiliau Hōkū, helu 1 trillion hoku (10 ^12), a me ka nō hoʻi - 1 ieeeea? (3 m 10 ^11). Eia naʻe, he manawa e hookui hookahe koko ana o ke ano lani kahi mea negligible, no ka mea, he mamao loa ma waena o lākou. No ka laʻana, ka mea kokoke hoku i ka Sun Proxima Aia ma ke kaawale ana o ka 4.2 makahiki malamalama (4 * 10 ¹³ km), a me 30 miliona (3 m 10 ⁷⁾ Sun ka ho. Manao wale ia mākou hōkū - he poepoe no ka pāʻani papa Hana. A laila, Proxima Centauri, e nana, e like me ka pea, Aia ma ka mamao o 1.100 ei aku, a me ka nō hoʻi nae waho mai i 30 miliona kilomika. ʻO ka hoku ma ka waena konu o ka Wiliau Hōkū (a me keia mea ma ka lehulehu nui o ia) e ke aupuni 'maʻanuʻu o ka 160 ieeeea? (1.6 × 10 ¹¹⁾ ei. O e like me ka mea poepoe no ka papa Hana ma kela 3.2 ei. Nolaila, i ka hiki wale mai ka wā merging galaxies i kekahi mau hoku collide, mea'āina uuku.

Hookui hookahe koko ana o Black puka

Andromeda a me nō hoʻi i Central supermassiveʻeleʻele lua signSagittarius A (3.6 * ¹⁰ June ka ikehu lā nā paʻi hua) a me ka mea i loko o ka huhui waina a lākou P2 Galactic nucleus. Mauʻeleʻele lua akoakoa ana ma kekahi wahi kokoke i ka piko o ka lānai hou i hana galaxies, maalo ae la oia i ka ikehu orbital o na hoku, a ma manawa e hoʻololi i ke ala kiʻekiʻe. Ka luna kaʻina e lawe miliona o ka makahiki. I ka wā e hoʻokokoke akuʻeleʻele lua i ke kaawale ana o kekahi malamalama makahiki mai kekahi i kekahi, e hoʻokuʻu akula ka mea, gravitational nalu. Orbital ikehu e lilo i nui loa aku kou mana, a hiki i ka hoʻokuʻi pū ua ana loa. Ma muli o hōʻuluʻikepili, mālama 'ia ma 2006, o ka Honua hiki ke initially i kāpaeʻia kokoke i ka loa konu o ka lānai hou i hana Wiliau Hōkū, a laila ka mea, e lawe ma kahi o kekahi o kaʻeleʻele lua, a e hana hewa ma o aku o Mlekomedy.

e hooiaio ai kumumanaʻo

Ka Andromeda Wiliau Hōkū e holo mai ana iā mākou ma ka mämä holo o ma kahi o 110 kilomika no kekona. Up a 2012, aole he ala e ike ina paha i ai kekahi hookui hookahe koko ana, e kānāwai. Manao nei makou ia mea kokoke inevitable, nä känaka 'epekema kōkua mai i ka Hubble Space Telescope. Ma hope o ka hoʻokoloʻana Andromeda neʻe mai ka 2002 a hiki i ka makahiki 2010, ka mea i manao ai, aole i ka hookui hookahe koko ana, e hiki mai ana ma kahi o 4 ieeeea makahiki.

Similarʻike manaʻo i laha ma na cosmos. No ka laʻana, ka mea, ua manaoio aku i ka Andromeda hope pāʻani aku me ma ka liʻiliʻi loa hoʻokahi Wiliau Hōkū. Kekahi dwarf galaxies e like me SagDEG, a e hoʻomau i ka halawai ana me ke nō hoʻi, e pili ana i ka hookahiʻahahui.

Haʻawina no hoi hōʻike i M33, ka Triangulum Wiliau Hōkū, a, - i ke kolu o ka nui loa, a me ka loa,''he Luna o ka Local Group - E i komo i loko o kēia hanana. Ka hapanui o ia paha ka mea, e ia i ka hopena o ke komo i loko o ka Astronomical i hanaʻia ma hope o ka hoʻokuʻi pū o ka mea, a ma ka wā e hiki mai no ke kaawale ana - i ka hope loa unification. Eia naʻe, M33 hookui hookahe koko ana a me ka nō hoʻi ma mua kokoke Andromeda a me ko kakou poe lń e e kiolaʻia ma kēlāʻaoʻao o ka Local Group, ua hoʻokoe '.

I ka hopena o ka poe lń

Epekema mai Harvard hoʻopaʻapaʻa ana i nā hua'ōlelo o ka hui ana o galaxies hilinaʻi ma ka tangential māmā holo o ka Andromeda. Ma muli o ka helu, ua manao ia he mea he 50% hiki wale mai ia ma ka confluence o ka poe lń e e kiola ana i ka mamao o ekolu mau manawa oi aku ma mua o ke kala pono o ka waena nō hoʻi. Aloha mai e ike pehea e hele i loko o ka Andromeda Wiliau Hōkū. Honua, no hoi, o lalo o hoʻoweliweli. ʻepekema i aku nei au he 12% pahiki kekahi manawa e mākou i ma hope o ka hookui hookahe koko ana, e e pahu hoʻi ma o aku o ko makou mua "hale". Akā, i kēia hanana mea ole paha i ka paka loa adverse 'ole ma o ka poe lń, a me na kino lani, e ole e luku.

Inā mākou e hookaawale ia i ka planetary ka hana 'enekinia, a laila, i ka manawa o ka hookui ana o galaxies ua glowing nui ili o ka honua, a me ka mea e ole noho wai a ka wai, a pela ke ola.

Hikiʻaoʻao waiwai

Ka wā mau spirals i hui, ka hydrogen makana ma luna o lākou nā pā'opihia. Ua hoʻomaka mālama nui ho okumu o hou hoku. No ka laʻana, ka mea hiki ke mālama i loko o ka interacting Wiliau Hōkū NGC 4039, ole ike like "antennas". Ma ka hanana o ka hoʻokuʻi pū o Andromeda a me ka nō hoʻi ua manaoio aku i ke kinoea i loko o lākou a holo, e nohoʻuʻuku. Ka hoku e ole e like, pili, naʻe ka mea hoʻoneʻe 'ia paha i ka muli o ka quasar.

merge hopena

Wiliau Hōkū i hanaʻia ma ka huina, noiʻi mua haawiia Mlekomeda. Ke hōʻulu? Acoeueoao hōʻike i ke kūpono mea, e ia o ka elliptical shape. Kona oaio? E i ka haʻahaʻa nuʻa o hoku ma mua o kaʻiʻo nō o kēia elliptical galaxies. Akā, paha i hoʻopoepoe shape. Nui, e hilinaʻi ma i ka nui o ke kinoea i koe i loko o ka nō hoʻi a me Andromeda. I ka wā e hiki mai ma kahi o na galaxies o ka Local Group i koe, e merge i hookahi o kaʻahahui, a me ka mea e hoailona i ka hoʻomaka o ka hou evolutionary ke kahua.

Kūʻiʻo e pili ana i Andromeda

• Andromeda - ka nui Wiliau Hōkū i loko o ka Local Group. Akā, paha i ka loa papakaukau. ʻepekema theorize i loko o ka nō hoʻi i hoʻomōhala nui pouli mea, a me ia mea ka mea mākou Wiliau Hōkū oi nunui.
• Epekema makaikai i Andromeda i ka mea e maopopo i ke kumu a me ka evolution o kēia mau me ka ho okumu ia, no ka mea, o ka mea kokokeʻoni iho Wiliau Hōkū iā mākou.
• Andromeda mai ka Honua oi ana, heʻe piʻoloke ihola. He nui a hiki kahu ai e kiʻi i ia.
• Andromeda i ka loa anuanu galactic nucleus. 'Aʻole wale nō, alahula mau hoku i aia i loko o ka konu, akā, no hoi ma ka liʻiliʻi loa hoʻokahi supermassiveʻeleʻele lua huna i loko o ka Kora naʻEsau.
• Konaʻoni iho i na mea kaua i ka hoʻoluli like me ka hopena o gravitational AaOIeIOUIeXAOAaIN ma waena o nā kokoke galaxies: M32 a me M110.
• Loko Andromeda ia ma ka liʻiliʻi loa 450 globular hoku huhui. Iwaena o lakou - kekahi o ka loa anuanu, e hiki ke huai ae.
• Andromeda Wiliau Hōkū - ka loa e loihi mea e e ike i ka maka kohana hiki. Oe, e pono i ka maikai vantage wahi a me ka palena iki glare.

Ma ka hopena, ua kūkā iho heluhelu pinepine hoala mai i ko lakou mau maka i ka starry lani. Ua malama i ka puu o ka hou a me ka ike ole. E huli i kekahi noa manawa e malama i ka cosmos ma ka hopena pule. Andromeda Wiliau Hōkū i loko o ka lani - o ka maka ia e maopopo leʻa ike.
