原文:
Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies 5 million year young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is just below center in this telescopic field of view with the angular size of the Full Moon on the sky. The cluster itself is about 200 light-years in diameter. Glowing interior ridges and swept back shapes strongly suggest that energetic radiation and shock waves from NGC 602’s massive young stars have eroded the dusty material and triggered a progression of star formation moving away from the cluster’s center. Of course, the more extended wings of emission in the region suggest a popular name for the complex cosmic environment, The Flying Lizard Nebula.
中文翻譯:
在小麥哲倫雲的邊緣，距離地球約200,000光年的地方，坐落著一個年輕的星團NGC 602，年齡約500萬年。它被新生的氣體和塵埃包圍，NGC 602 在此望遠鏡視野中位於中央略偏下的位置，其角度大小接近滿月。這個星團直徑約200光年。內部閃爍的山脊和向後仰的形狀，強烈暗示著來自NGC 602中大量年輕恆星的強大輻射和衝擊波，侵蝕著周圍的塵埃物質，並觸發了一波接一波的恆星形成，從星團中心向外擴展。當然，這一區域的擴展發射翼也為這個複雜的宇宙環境賦予了一個受歡迎的名字，飛行蜥蜴星雲（The Flying Lizard Nebula）。
