Ukuqoshwa kwemisindo Yezibani ZaseNyakatho, okubonisa ukuthi lesi simo sivame kakhulu kunalokho okwakucatshangwa ngaphambili, futhi kwenzeka ngisho nalapho kungabonwa, kwenziwa ngu-Unto Kalervo Laine - owayenguprofesa e-Aalto University eFinland kanye nochwepheshe bezobuchwepheshe bokukhuluma. Wethule umbiko engqungqutheleni yakamuva ye-EUROREGIO / BNAM2022 acoustics eDenmark. Sekuyiminyaka eminingi u-Laine efunda imisindo ehlotshaniswa ne-Northern Lights. Ngo-2016, washicilela ulwazi lokuthi ukuqoshwa kokuvela ngesikhathi se-aurora borealis kwakuhlobene namaphrofayili okushisa aqoshwe yi-Finnish Meteorological Institute (FMI). Le datha ayibonisi nje kuphela ukuthi ama-aurora angahlotshaniswa nemisindo, kodwa futhi aqinisekisa inkolelo-mbono kaLane ukuthi le misindo iphuma ekukhishweni kukagesi kungqimba oluguquguqukayo lwezinga lokushisa endaweni ephakeme ngamamitha angaba ngu-70 ngaphezu komhlaba. Izibonelo ezintsha zezibani zasenyakatho zaqoshwa ebusuku eduze kwedolobhana laseFiskars. Nakuba ukukhanya ngokwako kwakungabonakali ngaleso sikhathi, okuqoshiwe kukaLane kwathwebula amakhulu “emisindo ezwakalayo.” Lapho amarekhodi eqhathaniswa nezilinganiso zomsebenzi we-FMI geomagnetic, kwatholakala ukuhlobana okuqinile okusobala. Yonke imisindo yekhandidethi engu-60 ehamba phambili yayihlotshaniswa nezinguquko emkhakheni we-geomagnetic. "Ukusebenzisa idatha ye-geomagnetic eye yalinganiswa ngokuzimela, kungenzeka ukubikezela ukuthi imisindo ye-aurora borealis izoba nenembile ngo-90%," kusho u-Laine. Ukuhlaziywa kwakhe kwezibalo kuphakamisa ubudlelwano obucacile bembangela phakathi kwe-geomagnetic oscillations nama-auroras.
Ekupheleni kukaMashi 2022, ochwepheshe be-NASA babelane ngezinhlelo zokwethula amarokhethi amabili endaweni ephakeme ngamakhilomitha angaphezu kuka-200 ngokuqondile ezibanini ezisenyakatho ukuze bafunde kabanzi ngezinqubo zokushintshisana kwamandla phakathi koMhlaba nomkhathi. Lokhu kubikwe yi-portal ye-NASA. Ukukhanya kuzalelwa emngceleni ophakathi komkhathi kagesi ongathathi hlangothi ozungeze iplanethi kanye nesikhala se-interplanetary esigcwele izinhlayiya ezikhokhiswayo ezivela ku-plasma yomoya welanga, ezisebenzisana nenkundla ye-geomagnetic. Ukukhanya kwe-luminescent okuvela ngezansi kubukeka njengamaseyili amakhulu anemibala ehlukene namaza okukhanya adansayo. Kodwa isithombe asigcini ngombukwane womhlaba - ukusebenzisana phakathi kwezinhlayiyana kujabulisa izingqimba zomngcele obanzi womkhathi, futhi umthelela wezinhlayiya ezikhokhisiwe kulezi zingqimba ezingenhla othakazelisa i-NASA. I-ejensi ilungiselela namuhla e-Alaska umsebenzi we-INCAA - i-Ionic neutral compound ngesikhathi sokukhanya okusebenzayo. Awukho umngcele ocacile wesendlalelo lapho igesi engathathi hlangothi iphela khona futhi i-plasma iqala - kunendawo enkulu yomngcele lapho izinhlobo ezimbili zezinhlayiya zixubana khona, okuthi ngezikhathi ezithile zingqubuzane futhi zikhiphe ama-photon ama-wavelengths ahlukene. Umbala "woseyili" uncike ekubunjweni kwama-molecule asemkhathini: umoya-mpilo unikeza ukukhanya okuluhlaza okukhanyayo noma okubomvu, i-nitrogen - ebomvu noma ensomi. Irokhethi yokuqala ihlelelwe ukukhipha izinkomba zomhwamuko ezingenabungozi - amakhemikhali anombala afana nalawo asetshenziswa kwiziqhumane - ngaphambi kokufinyelela endaweni ephakeme engamakhilomitha angama-300. Izinkomba zomhwamuko zizodala amafu abonakalayo abacwaningi abangawabona besuka phansi, ngaleyo ndlela balandelele imisinga yomoya eduze nokukhanya. Irokhethi yesibili, ezokwethulwa maduze nje ngemuva kweyokuqala, ezofinyelela ubude obungaba ngu-200 km, izokala izinga lokushisa nokuminyana kwe-plasma ngaphakathi naseduze kokukhanya.
