Ejirila Iridium mee ihe na igwe na-enye ọkụ ọkụ nke igwe na-enweghị igwe na-enweghị igwe dị ka Voyager, Viking, Pioneer, Cassini, Galileo, na New Horizons. A họọrọ Iridium iji tinye mmanụ plutonium-238 na generator n'ihi na ọ nwere ike iguzogide okpomọkụ ọrụ nke ihe ruru 2000 °C na maka ike ya dị ukwuu.Ojiji ọzọ metụtara X-ray optics, karịsịa X-ray telescopes. A na-ekpuchi enyo nke Chandra X-ray Observatory na iridium nke ọkpụrụkpụ ya bụ 60 nm. A chọpụtara na iridium bụ ihe kasị mma e ji egbukepụ ụzarị ọkụ X mgbe e nyochachara nickel, ọlaedo, na platinum. A na-etinye akwa iridium, nke ga-adị larịị ruo n'ime atọm ole na ole, site n'itinye uzuoku iridium n'okpuru nnukwu agụụ n'elu akwa chromium. A na-eji iridium eme ihe na physics nke akụkụ maka mmepụta nke antiprotons, ụdị nke antimatter. A na-emepụta antiprotons site n'ịgba ụzarị proton dị elu n'ihe a na-atụgharị atụgharị, nke a ga-eji ihe dị elu mee. Ọ bụ ezie na enwere ike iji tungsten mee ihe kama, iridium nwere uru nke nkwụsi ike ka mma n'okpuru ebili mmiri na-akpata site na ịrị elu okpomọkụ n'ihi ụzarị ọkụ.  Ajụjụ: Olee otú iridium nke dị n'enyo ndị dị na Chandra X-ray Observatory hà?
