恒星紫外辐射 stellar ultra-violet radiation
- 热恒星的紫外辐射使星云发光。
Ultraviolet radiation from the hot star powers the nebular glow. - 同时,新恒星释放出强烈的紫外线辐射,加热了气体,从而是星云发光。
Meanwhile, newborn stars are emitting intense ultraviolet radiation, heating the gas and causing the nebula to glow. - 在来自星云中心蓝巨星紫外线辐射的压力下,这些由气体和尘埃组成的恒星形成区域尖端的电离氢分子将不复存在。
Ionized molecular hydrogen can be seen evaporating from the tips of these star-forming columns of gas and dust, under pressure of ultraviolet light from the nebula's central blue giant stars.
