ʻO kahi kime o nā kilo hōkū mai kahi papahana ʻepekema e ʻimi nei i ke ola extraterrestrial, ʻo ia ka hopena ʻo Stephen Hawking ka ʻāpana, ua ʻike wale i ka mea ʻo ia ka hōʻike ʻoi loa no kahi hōʻailona haole e hele mai ana mai kahi ākea.
ʻO ke kiko kikoʻī, ua loaʻa i nā kānaka noiʻi kahi "hōʻailona lekiō hoihoi" e hele mai ana mai Proxima Centauri, kahi ʻōnaehana lā kokoke loa, he 4.2 mau makahiki māmā wale nō ka mamao mai ka Lā.
ʻO ka hōʻailona
ʻO kahi hōʻailona lekiō pohihihi mai ko mākou hoanoho hōkū kokoke loa, ʻo Proxima Centauri, ke "ʻimi pono ʻia" e ka hui o nā astronomers mai ka papahana Hoʻolohe Breakthrough.
ʻO ka hōʻailona, i hōʻike ʻia me nā fluctuations liʻiliʻi wale nō i loko o kahi kaola kaha o nā alapine ma kahi o 980 megahertz - i kūlike i kahi ʻāpana o ka lekiō lekiō i nele i nā lawe ʻana mai nā ukali a me nā mokulele mokulele a i ʻole ke kanaka - ua loaʻa mua ʻia e ka lekiō ʻo Parkes Australia teleskopa i ʻApelila a Mei Mei 2019, e like me kahi hōʻike i paʻi ʻia e The Guardian.
ʻO ka hōʻailona, e like me ka ʻepekema, mai ka ʻaoʻao o ka hōkū ʻo Proxima Centauri, ʻo ia ka hoalauna kokoke loa o kā mākou lā i ka lewa.
Aʻe b
Hōʻike ʻia ʻo Centauri B ma ke ʻano o kahi maloʻo (akā ʻaʻole piha wai ʻole) pōhaku Super-Earth. ʻO kēia hiʻohiʻona kekahi o nā hopena i hiki ke loaʻa i nā manaʻomanaʻo o kēia manawa e pili ana i ka hoʻomohala ʻana o kēia exoplanet, ʻoiai ke ʻano maoli a me ke ʻano o ka honua i ʻike ʻole ʻia i nā ala i kēia manawa. ʻO Proxima Centauri b ka exoplanet kokoke loa i ka Lā a ʻo ka exoplanet kokoke loa hoʻi e hiki ke noho ʻia. Hoʻopuni ʻo ia iā Proxima Centauri, kahi dwarf ʻulaʻula me kahi mahana o 3040 K (ʻoi aku ka wela ma mua o nā ipukukui a no laila keʻokeʻo, e like me ka mea i hōʻike ʻia ma aneʻi).

ʻO Proxima Centauri he 4.2 mau makahiki mālamalama mai ka Honua (ʻaneʻane he 40 trillion mau kilomika) a ʻelua mau paneta i hoʻopaʻa ʻia, kahi kinoea gas like me Jupiter a me kahi honua like Pōhaku i kapa ʻia ʻo Proxima B i loko o ka "ʻāpana noho", kahi kahi kahi hiki ke kahe ka wai wai ma luna o ka honua.
Eia nō naʻe, no ka mea he ʻulaʻula ʻo Proxima Centauri, kokoke loa ka wahi noho i ka hōkū. ʻO ke kumu o kēia ua laka laka ʻia ka honua a hōʻike ʻia i ka radiation nui, a ʻaʻole paha e hiki i kekahi lāhui ke hana, ma ka liʻiliʻi o ka papa.
ʻO ke kolu o ka honua ma waena o ka ʻōnaehana?
ʻO ka hōʻailona, ka mea i pili ʻole i kekahi ʻāina a me nā kumuwaiwai i hana ʻia e ke kanaka kokoke i ka Honua, e loaʻa paha kahi wehewehe kūlohelohe. Pēlā nō naʻe, ua pūʻiwa ka poʻe kilo hōkū haole malihini i ka hōʻailona hōʻailona pohihihi.
No laila, ua ʻike ʻia ka lekiō lekiō ma ka 980 megahertz range, me ka hoʻololi ʻana i nā alapine i ʻike pinepine ʻia e ka teleskope Parkes, kūlike ia me ka neʻe ʻana o ka honua. Hōʻike kēia i hiki ke lilo i hōʻike o ke kolu o ka honua i loko o ka ʻōnaehana, ma mua o nā hōʻailona o ka lāhui haole, kahi mea a nā kānaka noiʻi i ʻōlelo ai he "ʻaʻole paha ia."
ʻO Pete Worden, ka luna o Breakthrough Initiatives, i haʻi aku i ke Kahu no ke ʻano o ka pale ʻana o nā hōʻailona mai nā kumu honua a mākou i wehewehe ʻole ai. Eia naʻe, ua ʻōlelo ʻo ia he mea nui ke kali a ʻike i ka hopena a ka ʻepekema papahana e nānā pono ai i ka hōʻailona.
ʻO Wow!
Wahi a ke kime ʻo kēia kekahi o nā lekiō leʻaleʻa hoihoi hope loa ka Wow! ka mea i alakaʻi i nā mea he nui e kuhi no ka lāhui haole mamao.
ʻO Wow! ua lawe ʻia kahi hōʻailona lekiō lōkole, a ua ʻākoakoa ʻia kahi lekiō i ka wā e ʻimi nei i ka papahana no ka ʻike extraterrestrial (Seti), e ka Big Ear Radio Observatory ma Ohio i ka makahiki 1977.
ʻO ka hōʻailona ʻokoʻa, ka mea i loaʻa ka inoa ma hope o ka mea kilokilo ʻo Jerry Ehman i kākau ʻo “Wow!” Me nā ʻikepili, ua hū aʻe ia i kahi nalu o ka pīhoihoi, ʻoiai ua ʻōlelo ʻo Ehman e kūʻē i ke kaha kiʻi ʻana i nā "hopena nui mai nā ʻikepili waena."
