Nkà mmụta mbara igwe nke ultraviolet

Astronomy ultraviolet bụ nleba anya nke radieshon electromagnetic na ultraviolet wavelengths n'etiti ihe dịka 10 na 320 nanometers; A na enyocha mbara igwe X-ray na mbara igwe gamma-ray na-amụ ogologo ebili mmiri dị mkpụmkpụ—photons ume dị elu. Anya mmadụ anaghị ahụ ìhè Ultraviolet. Ọtụtụ n'ime ọkụ ndị a dị n'ogologo ikuku na etinye uche na ikuku nke ụwa, n'ihi ya, a ga emerịrị ihe nleba anya n'okiri ụkwụ ndị a site na ikuku elu ma ọ bụ site na mbara igwe.
