Andromeda nebula - i ka noho ana o na mau Kakalema

Andromeda Wiliau Hōkū o kekahi o ka hoʻopuniʻana i kā mākou hale Wiliau Hōkū he mau huhui o ka nunui hoku. He hapa o ka ai-kapaia kūloko pae o galaxies, kona mau lala, i hou ia mea,ʻo mākou nō hoʻi me ka hoa Wiliau Hōkū a me ka Wiliau Hōkū o ka Triangle (a hiki no hoi i ukali, aka undiscovered). I mea, o ka hoʻopuniʻana i ka nō hoʻi ua uuku na huhui - ka Large a Small Magellanic ao. Ke Wiliau Hōkū iho e hoohui mai ia e pili ana i ka trillion hoku (i mea elima mau manawa nui ma mua o mākou iho), a me ka ke kahahńnai o kona hoa kanaka - oi ma mua o 110 tausani malamalama makahiki. Andromeda Wiliau Hōkū mea mai o mākou ma ke kaawale ana o elua a me ka hapalua miliona kukui-makahiki aku, a me ke kiʻi i ka loa hemolele no keia spacecraft makemake lawe 46 ieeeea makahiki. Kēia mea ma ka liʻiliʻi loa eono manawa oi aku ma mua o ka Honua i koe. Mau oeeo? Ua a hiki paʻakikī e noonoo ai i na!

I ka moolelo o ka loina o ka Wiliau Hōkū, he hoalauna

Anuanu huhui waina a lākou o ka hoku i loko o ka lani i ike ia ma ka Middle Ages. I ka pau, kekahi o na ¶ʻO'Arabaʻoihana o ka Andromeda Nebula ua haawi ia ia e like me ka meaʻuʻuku ao. Kēia lālā o ka hoku aia i loko o ka huihui o Andromeda (no ka mea, ma ka mea, nebula la kona inoa) i malama ia e astronomers no kenekulia. Eia naʻe,ʻaʻoheʻiʻo E hana 'ia i loko o kona hōʻikeʻano. Eia naʻe, ua 'ae i kaʻanoʻenehana uea' manaʻo kanaka e hana no i koe aku i loko o keia pili ana. I ka 1885, he mea i hana hoihoi hanana - i loko o ka Wiliau Hōkū Andromeda wawahi i ka supernova, a me ka noonoo ana o astronomers a puni ka honua huli i ka congestion. Eia naʻe, e like me kekahi mana, ua exploded lōʻihi aku nei, kekahi mau miliona makahiki aku nei, akā, i ka mea i kńnaka i maliuʻia no ka hanau ana o ka hou hoku - wale i ka malamalama mai ka Naita me ia, i mea wale manawa (aho paha e olelo, i ka 1885), hele mai i ka Honua. Andromeda nebula, kiʻi o i i mua i loaa i ka makahiki 1887, akaka i astronomers like me ka nui spiraling hono o na kino. Nani loa Kaka i loko o 1921 ma ka American Vesto Slipher. Helu ana i ke ala o ka Wiliau Hōkū, ka mea, ua loaʻa i ka Andromeda Nebula me ka weliweli wikiwiki ke kome pololei a hiki i kaʻaoʻao o ke nō hoʻi. E like me kēia helu o astronomers, i ka 4 ieeeea makahiki ia e merge na galaxies elua. 'Aʻole i kēia nana e like me ka hookui hookahe koko ana oʻelua hui waina o ka hoku akā, oiaio undergo nui e hōʻuluʻulu hou a me ka hoʻololi i ko lakou mau orbits. I Ka Nani hōʻoia i na mea he nui e e puʻe wale mai o ke kino, a hiki mai i loko o ka lānai hou i hana Wiliau Hōkū ma interstellar makahiki. He hana hoihoi 'ia ma 1993 ma ka waena konu o ka Andromeda Nebula i ike kekahi lālā o ka hoku. Paha ia mea i ka kumumea o ka Wiliau Hōkū, nebula ke kemu miliona o ka makahiki aku nei.

hiʻona nebula

E like me ka manaÿo o ke kālā no astrophysics, ma ka-oaio? A loaʻoni iho galaxies o ke awa supermassiveʻeleʻele puka. Ka mea, ua paʻakikī e ike no o ka puu nui o ke ano lani kahi ma ka waena konu o ka spirals, e like me ma muli o ka nele o ka malamalama, a me ka noʻonoʻo o ka malamalama. Eia naʻe,ʻeleʻele lua hiki ke 'akomi e nānā ana i ka mea, he aha ka mea'ē aʻe mea. He 'ike ia i loko o ka' ōlelo o ka Andromeda Wiliau Hōkū i kekahi hui malu pu ana o na puu moho supermassiveʻeleʻele puka.
