猎户座星云

This wide-field view of the Orion Nebula (Messier 42), lying about 1350 light-years from Earth, was taken with the VISTA infrared survey telescope at ESO’s Paranal Observatory in Chile. The new telescope’s huge field of view allows the whole nebula and its surroundings to be imaged in a single picture and its infrared vision also means that it can peer deep into the normally hidden dusty regions and reveal the curious antics of the very active young stars buried there. This image was created from images taken through Z, J and Ks filters in the near-infrared part of the spectrum. The exposure times were ten minutes per filter. The image covers a region of sky about one degree by 1.5 degrees.   #L

这幅猎户座星云 (Messier 42) 的广角照片距离地球约 1350 光年,是使用位于智利的 ESO 帕拉纳尔天文台的 VISTA 红外巡天望远镜拍摄的。
新望远镜的超大视野使整个星云及其周围环境可以在一张照片中成像,而它的红外视觉也意味着它可以深入通常隐藏的尘埃区域,并揭示埋藏在那里的非常活跃的年轻恒星的奇特行为。这幅图像是通过光谱近红外部分的Z、JKs滤光片拍摄的图像创建的。每个滤光片的曝光时间为 10 分钟。这幅图像覆盖了大约 1 度乘 1.5 度的天空区域。
