ʻElua ʻoi aku ka nui o ka Lā, ʻo ka hōkū ʻo HL Taurus i ʻike lōʻihi i ka nānā ʻana i nā telescope ma ka honua a me ka lewa.
Ua hāʻawi ka ALMA radio astronomy telescope (ALMA) i nā kiʻi kikoʻī mua o nā molekele wai i loko o ka disk kahi e hiki ai ke hānau ʻia nā hōkū mai ka hōkū ʻōpio loa ʻo HL Tauri (HL Tauri), i hōʻike ʻia e AFP, e pili ana i ka noiʻi i paʻi ʻia ma ka puke pai Nature Astronomers.
"ʻAʻole au i noʻonoʻo e hiki iā mākou ke kiʻi i kahi kiʻi o kahi moana mahu ma ka ʻāina kahi e hana ʻia ai ka honua," wahi a Stefano Facini, he mea kilo hōkū ma ke Kulanui o Milan a me ke alakaʻi kumu o ka noiʻi.
Aia i loko o ka constellation Taurus a kokoke loa i ka Honua - "wale nō" 450 mau makahiki māmā, ua lōʻihi ka nui o ka hōkū e like me ka Sun HL Taurus ma ke kahua o ka nānā ʻana i nā telescopes honua a me ka lewa.
ʻO ke kumu ʻo kona kokoke a me kona ʻōpio - ʻoi aku ka nui o hoʻokahi miliona mau makahiki - hāʻawi i kahi hiʻohiʻona kupaianaha o kāna disk protoplanetary. ʻO ia ka nui o ke kinoea a me ka lepo a puni ka hōkū e hiki ai i nā hōkū ke hana.
Wahi a nā kumu hoʻohālike, ʻoi aku ka hua o kēia kaʻina hana ma kahi kikoʻī ma ka disc - ka laina hau. ʻO kēia kahi e lilo ai ka wai ma ke ʻano o ka mahu ma kahi kokoke i ka hōkū, i mea paʻa i kona maʻalili. Mahalo i ka hau e uhi ana iā lākou, ʻoi aku ka maʻalahi o ka ʻili o ka lepo.
Mai ka makahiki 2014, ke hāʻawi nei ke telescope ALMA i nā kiʻi kūʻokoʻa o ka diski protoplanetary, e hōʻike ana i nā apo ʻālohilohi a me nā ʻawaʻeleʻele. Manaʻo ʻia ʻo ka mea hope e kumakaia i ka hele ʻana o nā hua o nā hōkū, i hana ʻia e ka hōʻiliʻili ʻana o ka lepo.
Hoʻomanaʻo ka haʻawina ua ʻike nā mea hana ʻē aʻe i ka wai a puni HL Taurus, akā ma kahi haʻahaʻa haʻahaʻa loa e wehewehe pono i ka laina hau. Mai kona kiʻekiʻe kiʻekiʻe ma luna o 5,000 mika ma ka wao nahele ʻo Atacama o Chile, ʻo ka telescope radio European Southern Observatory (ESO) ka mea mua e wehewehe i kēia palena.
Hoʻomaopopo pū ka poʻe ʻepekema, a hiki i kēia lā, ʻo ALMA wale nō ka hale e hiki ai ke hoʻonā spatially i ka noho ʻana o ka wai i loko o kahi diski hoʻokumu honua.
Ua ʻike ka telescope radio i ka like o ʻekolu manawa o ka nui o ka wai i loko o nā moana āpau o ka Honua. Ua ʻike ʻia ma kahi ʻāpana kokoke i ka hōkū, me ka radius like me 17 manawa ka mamao ma waena o ka Honua a me ka Lā.
ʻOi aku paha ke koʻikoʻi, e like me ka ʻōlelo a Facini, ʻo ka ʻike ʻia ʻana o ka mahu wai ma nā mamao like ʻole mai ka hōkū, me ka lewa kahi e hiki ai ke hoʻokumu ʻia ka honua.
E like me ka helu ʻana o kahi mea nānā ʻē aʻe, ʻaʻohe hemahema o ka mea maka no kona hoʻokumu ʻana - ʻo ka nui o ka lepo i loaʻa he ʻumikumamākolu manawa o ka Honua.
No laila, e hōʻike ana ke aʻo ʻana i ke ʻano o ka hiki ʻana o ka wai ke hoʻopilikia i ka hoʻomohala ʻana o kahi ʻōnaehana honua, e like me 4.5 biliona makahiki i hala aku nei i loko o kā mākou ʻōnaehana solar, wahi a Facini.
Eia nō naʻe, ʻaʻole paʻa ka hoʻomaopopo ʻana i ke ʻano o ka hoʻokumu ʻana o nā hōkū o ka Solar System.
