ʻO nā leo o nā leo o ka Northern Lights, e hōʻike ana he ʻoi aku ka maʻamau o kēia ʻano ma mua o ka mea i manaʻo ʻia ma mua, a hiki i ka wā i nānā ʻole ʻia, ua hana ʻia e Unto Kalervo Laine - he kumu mua ma ke Kulanui ʻo Aalto ma Finland a he loea i ka ʻenehana haʻiʻōlelo. Ua hōʻike ʻo ia i kahi hōʻike ma ka hālāwai kūkā acoustics EUROREGIO / BNAM2022 i Denmark. No nā makahiki he nui, ke aʻo nei ʻo Laine i nā leo e pili ana me ka Northern Lights. Ma 2016, ua hoʻopuka ʻo ia i ka ʻike e pili ana nā leo o ka popping i ka wā aurora borealis me nā kiʻi wela i hoʻopaʻa ʻia e ka Finnish Meteorological Institute (FMI). ʻAʻole hōʻike wale kēia mau ʻikepili i hiki ke hoʻopili ʻia nā aurora me nā leo, akā hōʻoia pū i ka manaʻo ponoʻī o Lane i ka hopena o kēia mau kani mai ka hoʻokuʻu ʻana i ka uila i ka papa hoʻohuli wela ma kahi kiʻekiʻe o 70 mau mika ma luna o ka honua. Ua hoʻopaʻa ʻia nā hiʻohiʻona hou o nā kukui ʻākau i ka pō kokoke i ke kauhale o Fiskars. ʻOiai ʻaʻole ʻike ʻia ka ʻālohilohi i kēlā manawa, ua paʻa ka leo o Lane i mau haneli o nā "leo auroral." Ke hoʻohālikelike ʻia nā moʻolelo me nā ana hana geomagnetic FMI, ua ʻike ʻia kahi pilina ikaika. Hoʻopili ʻia nā leo moho maikaʻi a pau he 60 me nā loli i ke kahua geomagnetic. "Me ka hoʻohana ʻana i ka ʻikepili geomagnetic i ana kūʻokoʻa, hiki ke wānana i ka wā e 90% pololei ai nā kani aurora borealis," wahi a Laine. Hōʻike kāna ʻikepili helu i kahi pilina kumu ʻole ma waena o nā oscillations geomagnetic a me auroras.
I ka pau ʻana o Malaki 2022, ua haʻi ka poʻe loea NASA i nā hoʻolālā e hoʻolauna i ʻelua rockets ma kahi kiʻekiʻe o 200 km pololei i nā kukui ʻākau e aʻo kikoʻī i nā kaʻina hana o ka hoʻololi ʻana i ka ikehu ma waena o ka Honua a me waho. Ua hōʻike ʻia kēia e ka portal NASA. Hānau ʻia ʻo Radiance ma ka palena ma waena o ka lewa uila a puni ka honua a me ka lewa interplanetary i hoʻopiha ʻia me nā mea i hoʻopaʻa ʻia mai ka plasma o ka makani lā, e launa pū ana me ke kahua geomagnetic. ʻO ka ʻōlinolino o lalo e like me nā canvases nui o nā waihoʻoluʻu like ʻole a me nā nalu māmā. Akā, ʻaʻole i kaupalena ʻia ke kiʻi i ka nānā ʻana o ka honua - ʻo ka pilina ma waena o nā ʻāpana e hoʻohauʻoli i nā ʻāpana palena ākea o ka lewa, a ʻo ka hopena o nā mea i hoʻopaʻa ʻia ma kēia mau papa luna e hoihoi iā NASA. Ke hoʻomākaukau nei ke keʻena no kēia lā ma Alaska i ka misionari INCAA - Ionic neutral compound i ka wā o ka ʻōlinolino ikaika. ʻAʻohe palena maopopo o ka papa kahi i pau ai ke kinoea kūʻokoʻa a hoʻomaka ka plasma - aia kahi palena palena nui kahi e hui ai nā ʻano mea ʻelua, kahi e hui ai i kēlā me kēia manawa a hoʻopuka i nā photon o nā lōʻihi hawewe like ʻole. ʻO ke kala o nā "peʻa" e pili ana i ka hoʻokumu ʻana o nā molekele lewa: hāʻawi ka oxygen i kahi kukui ʻōmaʻomaʻo a ʻulaʻula paha, nitrogen - ʻulaʻula a poni paha. Hoʻolālā ʻia ka rocket mua e hoʻopuka i nā hōʻailona mahu ʻino ʻole - nā kemika kala e like me nā mea i hoʻohana ʻia i ke ahi - ma mua o ka hiki ʻana i kahi kiʻekiʻe o 300 km. E hana nā ʻōkuhi mahu i nā ao ʻike ʻia e hiki i ka poʻe noiʻi ke nānā mai ka honua, no laila e ʻimi ana i nā au ea kokoke i ka ʻālohilohi. ʻO ka lua o ka rocket, e hoʻokuʻu ʻia ma hope koke o ka mea mua, hiki i ke kiʻekiʻe o 200 km, e ana i ka mahana a me ka nui o ka plasma i loko a puni ka ʻālohilohi.
