I teenna leitung thakhatthu a asiat nading apiangsak thei nam gukte

Feb. 1, 2017: I teenna leitung pen nuclear zanga gal omna, leitung lum luatman (global warming) ahih leh natna lianpi a pian’na hangin beimang thei hi kici. Ahih hangin hih thu thumte pen kipelh thei napi leitung thakhat thu-in a siat gawpna (catastrophes) theihna ding thu nam guk hangin a siat ding kipelh thei lo hi ci-in Conservative news laipaih (articles) ah Nottingham Trent University-a Lecturer in Astronomy sem Daniel Brown in thu nam guk a gente en dih ni.

1. High energy solar flare: Ni pen aksi nam khat banga kingaihsun a cingkam leh siatna a piangsak lo (peaceful star) bangin a kingaihsut hangin magnetic fields kici ni sungah tampi om a, tua munte pen i teenna leitung sangin golzaw hi. Tua munte ah radiation hangin ni huih (solar wind) kici om thei a, tua-in mihingte sih theihna ding na them nono (particles) leh radiation kici piangsak thei hi. 1859 in zong ni panin huihpi (solar storm) in leitung na nawk ngei a, tua pen Carrington Event kici a, electronic van tampi tak na sia gawp hi. Caring Event banga hatzaw hong piang kik leh mei (electricity), a lumsakna (heating), AC, GPS leh internet khempeuh a siat banah zatui leh nek ding an khempeuh kisia khin ding hi.

2. Asteroid impact kici aksi them kia suang ten leitung hong deng leh mihing tampi kisi ding hi. Asteroids in leitung a deng manin ganhing gol mahmah dinosaur kici khempeuh na bei (extinct) hi kici hi. Asteroids gol ten leitung hong deng leh mihingte nuntakna bei zo ding kici hi (Mangmuhna LST sim leng zong aksi leh khapi a kim khat in leitung deng hi cih i mu thei hi).

3. Expanding sun kici ni pen khan’ beh leh atmosphere pua-ah planetary nebuba kici kibawl ding hi. Ni pen kum 7.72 billion in a upat ciangin si ding hi ci-in scientists ten ci uh hi. Tua bangin ni in a golna behlap hi leh vantunga om na gol (stellar giant) ten Mercury leh Venus umcih zo ding uh hi. Solar wind hangin ni liat beh dinga, i teena leitung pen a pua lamah (outer layers) ah kikhin dinga, aksi site bangin malh/tuisuak (melt) ding ahih manin mihingte kinungta zo lo ding hi.

4. Local gamma ray burst kici a hat mahmah gamma ray puakkham hangin ni, kha leh planet tuamtuamte a kimkot binary star systems (two stars orbiting a common centre) pen puak kham dinga, second tam lo sung ahih kei leh minute tam lo sungin puakkham ding hi. Hih bangin a puakkhapna hangin sih theihna ding radiation a dal ozone layer kici kisia dinga, aksi puakkham (supernovas) piang ding ahih manin ni panin UV radiation in i teenna leitung hong nawk dinga, mi khempeuh kisi khin ding hi.

5. Nearby supernovas kici pen aksi puakkham (Supernova explosions) pen aksite a nutakna ding hun a bei ciangin puakkham hi. Aksi puakkham pen aksi lom omna Milky Way kicihna ah kum 100 sungin nih vei bang puakkham den hi. Milky Way panin leitung kigamla lua ahih manin a kisi khin lo hi bek hi. Betelgeuse aksi kici pen aksi san gol mahmah hi a, si dekdek ta hi. A oman kiim Orion panin 460-650 light years (light years kici pen 5.88 trillion miles or 9.46 trillion kilometers ahi hi) in gamla in om hi. Kum million sanga tamzaw deuh khit ciangin hih aksi san puak kham dinga, a upak khapna hangin sih theihna radiation a khak khiat ding pen light yraes 50 bangin kigamla hi.

6. Moving stars (aksi kikhin) pen aksi vak thapte (wandering stars)
Milky Way kiim-ah vak kawikawi uh a, ni tawh va kinaih tektek uh hi. Tua bangin aksi vakthapte pen suangtum golpi hi uh a, ni kiim-a om “Oort cloud” kicihna mun nawl tawh va kitaih khat le uh aksi them kia (comets) i cih ten leitung hong deng dinga, nuntakna nei khempeuh kisi khin ding hi. Ni nangawn aksi lomte omna Milky Way kiim a kimkot hi a, interstellar gas kim-ah kimkot ahi hi. Tua hangin aksi puak kham (supernova) tam zaw panin i teenna leitung hong dal in hong humbit thei hi.

Ni’ huih (sun’s wind) ni sunga om magnetic field kici in a phuan banga a omana kiim bubble-like solar system kici sunga om heliosphere in interstellar medium kici tawh in leitung hong nawkna ding hong dal hi. Hih kiim pen kum 20,000 to 50,000 sungin heliosphere ah zat theih mel kei leh leitungah khuahun lumna leh votna nakpi takin kilaih dinga, nuntakna nei khempeuh si khin ding hi.
