He aha mea he Wiliau Hōkū, a me ka mea mau mea?

Ka poe i makemake e nānā i ka lani ka po, paha i kekahi ke akea koa a paa i paaʻano (alohilohi, māhunehune perceptible, uliuli, keʻokeʻo, etc.) hoku. Kēia lālā o ka Wiliau Hōkū.

He aha mea he Wiliau Hōkū? Kekahi o na mea pohihihi nui loa o ka ke ao holoʻokoʻa moe i loko o ka mea i olalo i hoku i ole hele liʻiliʻi randomly ma ka makahiki, a ua Hoʻohui 'i loko o galaxies. I ka nui o ka ia ala kanaka noho i ke kulanakauhale, e waiho i ka wa ma waena o ka noho nele.

I ka Honua i kekahi hapa o ka Wiliau Hōkū ka nō hoʻi. Kekahi inoa o galaxies mea pono i ike: ka Large a Small Magellanic ao, ka Andromeda Wiliau Hōkū. Ia mākou keʻike i ka maka kapa ole, oiai kekahi poe i loa mamao mai ka Honua. Muli o kona kulana he lōʻihi manawa ole e ike i loko o ia i kekahi mau hoku, e huli mai, e e wale nō i loko o ka 20th kenekulia.

"He aha ka He Wiliau Hōkū?" - keia ninau i lōʻihi piliʻepekema. Akā,ʻo maoli Hopu i loko o kēia wahi iloko ma ka hopena o iwakalua o ke kenekulia, ka wā ia i hana, a ee i loko o ka lewa telescope "Hubble".

I ka nui o ko mākou Wiliau Hōkū mea ai nui i ka mea mea hiki ole ia i noonoo ai i na. Hoʻokahi haneri tausani kānaka Honua makahiki, e pono i ka malamalama nana i ulana, e hiki ia ia me kekahiʻaoʻao no ka mea 'ē aʻe. Ma kona oaio? Ua aia ka nucleus mai i kekahi mau lālā spiraling laina piha me ka hoku. "Nuʻa" keia mea maopopo wale, ma ka mea ka mea, i ke aupuni 'he pohihihi keia.

Aia i nāʻano o nā galaxies. Ka mea, oko in shape, kau paona ana, nui, e like me ka waiwai i kakauiaʻi maluna. I mai la lakou a pau iloko o ka kinoea a me ka hoku i ka lepo. Aia iʻoni iho, elliptical, ole, poepoe-e like me na ano o galaxies.

He aha mea he Wiliau Hōkū? He aha ka lākou mau makahiki? Pehea e hanaʻi? He aha keʻano o ka hanaʻana i loko o wahi? Lākou mau makahiki ke kaha like kokekau i ka makahiki o ka ke ao holoʻokoʻa. No kaʻepekema mea mea nō he mea pohihihi, mea o ka 'ōlelo o ka Wiliau Hōkū. Ua Ua ua 'ike akula i kekahi nuclei i loa kaila. Ua he mea haohao ia, no ka mea, a hiki i keia Kaka, ka mea i manaʻo i ka nucleus mea he anuanu hono o na haneri o ka miliona o ka hoku. Ka pāhawewe ('ōnohi a me ka Radio) i ĸokoĸa ana nä pane ma kekahi galactic Kora naʻEsau i loko o kekahi mau mahina. Kēia 'o ia hoʻi i ka mea, hookuu aku i alahula mau dala o ka ikehu (nui aku ma mua i loko o ka waihonaʻike supernova) i loko o ka pōkole manawa.

I ka makahiki 1963, ka mea hōʻike he mea pono hou ia i ka helehelena hoku-hoʻokino lakou i kapaia quasars. Lākou luminosity, e like me ka mea huli mai, hiki i oi luminosity galaxies. Ka mea, Ua kahaha ko oukou naau i ka olinolino o ka quasars e ĸokoĸa ana nä pane.

Ho okumu ana o galaxies - ia mea he kumu kaʻina hana o ka evolution o ka ke ao holoʻokoʻa, e kahe ana ma lalo o ka aoao o gravitational koa. Keʻano o nā 'ano a me nā kinona o galaxies mea aie a hiki i keʻano o nā kumu i loko o i i hanau iho la lakou. Mīkini'opihia o ka Wiliau Hōkū hiki hope 3 ieeeea?. Nam. I keia manawa, ke kinoea i ka hou 'ana ma o ka hoku nenoaiu. Ia mea ma ka mīkini'opihia o ke kinoea ao hana a me ka hoku (ma ka kekahi nuʻa a me ka wela lawa no kuʻi nukeliu keʻano o ka hanaʻana).

Ua interstellar kinoea me ke koe i ke depleted, a me ke kahua o ka hoku i emi, pili. Ka wā a pau kumu waiwai i ka maluhiluhi, heʻoni iho Wiliau Hōkū ia iho i loko o lenticular, iloko olaila loa o kaʻulaʻula hoku. Keia kahua i elliptical galaxies nona ka kinoea kumu waiwai i kana a kekahi 15-20 ieeeea? A £. Makahiki aku nei.

He nui nā kanaka i ka manaʻo o ka mea i Wiliau Hōkū ua hana o ka lehulehu 'epekema fiction kiʻiʻoniʻoni, ka meʻe ka poe i aloha aku, e hele i ke aouli o ka lewa, e kipa i ka ike ole kŘhele a me galaxies. I mea, keia ua i? Oaony no ka mea foreseeable wā e hiki mai. Oia hoi, ina ua hoʻoneʻe i ka mämä holo o ka malamalama (i hiki ole e lōʻihi), a laila, i ka Andromeda Wiliau Hōkū (mākou hapa Wiliau Hōkū) mākou kiʻi wale nō ma hope o 2,5 miliona makahiki. 'Oiai, (e like me ka helu o nā astronomers) e holo mai ana iā mākou, a ma ka 4-5 ieeeea makahiki,ʻalo me mākou nō hoʻi, a e alakai ai i ka ho okumu ana o ka hou elliptical Wiliau Hōkū.
