The Orion Nebula

Orion - achị n'elu akụkụ ebe ndịda nke elu-igwe nnukwu ìgwè kpakpando. The Orion Nebula-atụle ga-icheku emission Nebula, nke bụ n'okpuru na-akpọ "belt" nke ìgwè kpakpando. Ọ bụ n'ihi na a "belt" dị mfe inweta Orion nke elu-igwe. Ọ mejupụtara atọ ọcha na-acha anụnụ anụnụ na kpakpando Mintaka, cial, Alnitak. All na-emi odude na otu akara na na hà angular anya n'ebe onye ọ bụla ọzọ. Nke a ìgwè kpakpando bụ ebube na eziokwu na e nwere ọtụtụ na-egbuke egbuke ibu kpakpando. Otu kpakpando nke Orion yiri a bit bịara ikiri. Mgbe edebe ya site na a teliskop doro anya na anya inyoghi blur. Ọ na-akpọ "The Great Nebula na Orion", nke a gigantic ígwé ojii nke na-ekpo ọkụ, egbuke gas.

Banyere size of a gas ígwé ojii nwere ike ikpe site na eziokwu na site na ya na anyị ga-10,000 kpakpando dị ka anyanwụ. Nke a obere Orion Nebula yiri nnọọ n'ihi na ọ bụ site Earth na a anya nke 1340 ìhè afọ. Achasi gas daputara ọtụtụ na-ekpo ọkụ na-eto eto na kpakpando na nsọtụ nke a ibu molekụla n'ígwé ojii nke interstellar. The ụwa dum nke na n'ígwé ojii nke Nebula, gụnyere Horsehead Nebula, maka 100 puku. Afọ, ga-agbasasịkwa na eluigwe.

Enyocha mbara igwe kwere ebe gburugburu ìgwè kpakpando Orion, ihe ndị kasị mma nke elu-igwe. Nke a asị ibe Nebula bụ na-egbuke egbuke. Ya elu, nke gbatịrị fọrọ nke nta ka 80x60 nkeji nke aak, ukwuu karịa ebe nke ọnwa ugboro anọ na mgbukepụ ruru ihe dị ka 4 kpakpando ịdị ukwuu (ịdị ukwuu bụ egosi nke ìhè kere eluigwe ihe) nwere ezigbo visibiliti na mbara igwe n'abalị.

The teliskop nwere ike hụrụ na na ugwu nke ájá na-aga a na-agba ọchịchịrị warara na-ekewa ugwu-ọwụwa anyanwụ nke Nebula si ya isi ahụ.

N'ihi Hubble Space teliskop, NASA ọkà mmụta sayensị achọpụtawo a protoplanetary disk, bụ nke dị na etiti nke Nebula akpọ "Trapezium". The ebe nwetara aha ya ekele 4 oke kpakpando, nke mere ndokwa na a trapezoid udi. Nebula bụ nnọọ ọrụ obi na-eto eto na kpakpando, na-ekpo ọkụ gas na ájá. Ike isi mmalite nke-acha anụnụ anụnụ na-egbukepụ egbukepụ na etiti nke ọ bụ na ya 4 nnọọ na-egbuke egbuke Trapezium kpakpando.
