I ka manawa hea i hana ʻia ai ka Lā?

i ka wa i hana ai ka la

Mahalo i ka lā hiki iā mākou ke ola ma ko mākou honua. Aia ka honua i kahi ʻāpana i kapa ʻia ʻo ka habitable zone kahi, mahalo i ka mamao mai ka lā, hiki iā mākou ke hoʻohui i ke ola. Eia naʻe, ua nīnau mau ka poʻe ʻepekema i ka wa i hana ai ka la a mai laila mai i hana ʻia ai ka ʻōnaehana solar i kēia lā.

Ma kēia ʻatikala e haʻi mākou iā ʻoe i ka wā i hana ʻia ai ka lā, kona ʻano a me kona koʻikoʻi.

He aha ka lā

'ōpona lā

Kapa mākou i ka lā ka hōkū kokoke loa i ko mākou honua (149,6 miliona km). ʻO nā hōkūhele a pau o ka ʻōnaehana solar e hoʻopuni ana iā ia, i huki ʻia e kona ʻumekaumaha, a me nā comets a me nā asteroids e hele pū ana me lākou. He hōkū maʻamau ka Lā ma ko kākou galaxy, ʻo ia hoʻi, ʻaʻole ia e kū i waho no ka nui a i ʻole ka liʻiliʻi ma mua o nā hōkū ʻē aʻe.

He Dwarf melemele G2 ia e hele ana ma ke kaʻina nui o kona ola. Aia ia ma ka lima wili ma ka ʻaoʻao o ka Milky Way, ma kahi o 26.000 mau makahiki māmā mai kona kikowaena. Ua lawa ia no ka helu ʻana i ka 99% o ka nui o ka ʻōnaehana solar, a i ʻole 743 ka nui o ka nui o nā hīkū āpau o ka honua hoʻokahi i hui ʻia (ma kahi o 330.000 mau manawa o ka nui o ka Honua).

ʻO ka lā, ma kekahi ʻaoʻao, He 1,4 miliona kilomika kona anawaena a ʻo ia ka mea nui loa a ʻoi aku ka mālamalama o ka lani o ka Honua., ʻo kona hele ʻana e ʻokoʻa ke ao a me ka pō. Ma muli o ka hoʻokuʻu mau ʻana o ka pāhawewe electromagnetic (me ka mālamalama i ʻike ʻia), loaʻa i ko mākou honua ka wela a me ka mālamalama, e hiki ai ke ola.

I ka manawa hea i hana ʻia ai ka Lā?

i ka wa i hana mua ai ka la

E like me nā hōkū a pau, ua hana ʻia ka Lā mai ke kinoea a me nā mea ʻē aʻe i ʻāpana o ke ao o nā molekala nui. Ua hāʻule ke ao ma lalo o kona umekaumaha 4.600 biliona makahiki aku nei. Hele mai ka ʻōnaehana solar holoʻokoʻa mai ke ao like.

ʻO ka hopena, lilo ka mea kinoea i mea paʻa loa e hoʻoulu ai i ka hopena nuklea e "hoʻā" i ke kumu o ka hōkū. ʻO kēia ke kaʻina hana maʻamau no kēia mau mea.

I ka pau ʻana o ka hydrogen o ka lā, ua hoʻololi ʻia i ka helium. He poepoe nui ka La o ka plasma, aneane puni loa. ka nui o ka hydrogen (74,9%) a me ka helium (23,8%). Eia kekahi, loaʻa iā ia nā mea trace (2%) e like me ka oxygen, carbon, neon a me ka hao.

ʻO ka hydrogen, ka mea puhi ahi o ka lā, e hoʻololi i ka helium ke hoʻopau ʻia, e waiho ana i kahi papa o "helium lehu." E piʻi aʻe kēia papa i ka wā e hoʻopau ai ka hōkū i kona pōʻai ola nui.

ʻO ke ʻano a me nā ʻano

ʻano o ka lā

Noho ke kumu i ka hapalima o ka hale o ka lā. He poepoe ka la a palahalaha iki ma na kia ma muli o kona nee kahuli ana. ʻO kona koena kino (ka ikaika hydrostatic) ma muli o ka counterweight o loko o ka ikaika umekaumaha nui e hāʻawi iā ia i kona nuipa a me ka pahu o ka pahū kūloko. Hana ʻia kēia pahū e ka hopena nuklea o ka hui nui o ka hydrogen.

Hoʻonohonoho ʻia i nā ʻāpana, e like me ka aniani. ʻO kēia mau papa:

  • Nucleus. ʻO ka ʻāpana o loko. Noho ʻo ia i ka hapalima o ka hōkū a he radius a pau ma kahi o 139.000 km. ʻO kēia kahi i pahū ai ka atomika nui ma ka lā. He ikaika loa ka huki umekaumaha i loko o ke kumu i hiki ai i ka ikehu i hana ʻia ma kēia ʻano he miliona makahiki e piʻi aʻe i luna.
  • ʻāpana ʻālohilohi. Hana ʻia me ka plasma (helium a me ka hydrogen ionized). Mālama kēia wahi i ka ikehu o loko mai ka lā e hoʻomālamalama maʻalahi i waho, e hoʻemi nui ana i ka mahana o kēia wahi.
  • convection zone. Ma kēia māhele, ʻaʻole i hoʻokuʻu ʻia ke kinoea, no laila ua ʻoi aku ka paʻakikī o ka holo ʻana o ka ikehu (photons) i waho a pono e hana ʻia e ka wela wela. ʻO ia ke ʻano o ka wela ʻole ʻana o ka wai, e hoʻonui ai, e nalowale ana ka nui, a me ka piʻi ʻana a me ka hāʻule ʻana o nā au, e like me ke kai.
  • Photosphere. ʻO kēia ka ʻāina e hoʻopuka i ka mālamalama ʻike ʻia mai ka lā. Ua manaʻo ʻia he mau ʻano hua ʻulaʻula lākou ma ka ʻili ʻeleʻele, ʻoiai he papa māmā ia ma kahi o 100 a 200 mau kilomita ka hohonu i manaʻo ʻia ʻo ia ka ili o ka Lā.
  • Chromosphere. ʻO ka ʻaoʻao o waho o ka photosphere ponoʻī he ʻoi aku ka translucent a paʻakikī ke ʻike ʻia no ka mea ua uhi ʻia e ka ʻālohilohi o ka papa mua. Aia ma kahi o 10.000 mau kilomita ke anawaena, a i ka wā o ka pō o ka lā, hiki ke ʻike ʻia me ka ʻulaʻula ma waho.
  • Lei lā. ʻO kēia nā ʻāpana lahilahi o ka lewa o waho o ka lā a ʻoi aku ka mahana o ka hoʻohālikelike ʻana i nā papa o loko. ʻO kēia kekahi o nā mea pohihihi o ke ʻano o ka lā. Aia ka haʻahaʻa haʻahaʻa o ka mea a me kahi mākēneki ikaika, kahi e holo ai ka ikehu a me nā mea ma nā wikiwiki kiʻekiʻe loa. Eia kekahi, ʻo ia ke kumu o nā kukui X.

mahana wela o ka lā

He ʻokoʻa ka mahana o ka lā ma kēlā me kēia māhele a ua kiʻekiʻe loa ma nā wahi āpau. Ma kona mau wela wela kokoke i 1,36 x 106 Kelvin (ma kahi o 15 miliona degere Celsius) hiki ke hoʻopaʻa ʻia, ʻoiai ma ka ʻili ke hāʻule i ka 5778 K (ma kahi o 5505 °C) a a laila hoʻi i luna ma 1 a i ʻole 2 Rise x 105 Kelvin.

Hoʻopuka ka lā i ka nui o ka radiation electromagnetic, hiki ke ʻike ʻia kekahi o ia mau mea he lā. He 1368 W/m2 ka mamao o kēia kukui a me ka mamao o hoʻokahi ʻāpana astronomical (AU), ʻo ia ka mamao mai ka Honua a i ka lā.

Hoʻemi ʻia kēia ikehu e ka lewa o ka honua, e ʻae ana ma kahi o 1000 W/m2 e hele i ke awakea mālamalama. Hana ʻia ka lā me 50% kukui infrared, 40% kukui mai ka spectrum ʻike ʻia, a me 10% kukui ultraviolet.

E like me kāu e ʻike ai, mahalo i kēia hōkū waena i hiki iā mākou ke loaʻa ke ola ma ka honua. Manaʻo wau me kēia ʻike hiki iā ʻoe ke aʻo hou e pili ana i ka wā i hana ʻia ai ka lā a me kona ʻano.


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia.
