Explanation: Distant galaxies and nearby nebulas highlight this deep image of the M81 Group of galaxies. First and foremost in this 80-exposure mosaic is the grand design spiral galaxy M81, the largest galaxy in the image, visible on the lower right. M81 is gravitationally interacting with M82 just above it, a large galaxy with an unusual halo of filamentary red-glowing gas. Around the image many other galaxies from the M81 Group of galaxies can be seen, as well as many foreground Milky Way stars. This whole galaxy menagerie is seen through the glow of an Integrated Flux Nebula (IFN), a vast and complex screen of diffuse gas and dust also in our Milky Way Galaxy. Details of the red and yellow IFN, digitally enhanced, were imaged by a new wide-field camera recently installed at the Teide Observatory in the Canary Islands of Spain.

解释:遥远的星系和附近的星云强调,这个星系M81星系团也是广阔深的形象。在这80曝光镶嵌的第一和最重要的是宏伟的设计螺旋星系M81,最大的星系在图像,可见在右下角。M81是与M82的引力相互作用,一个巨大的星系,有一个不寻常的晕的红色发光气体光晕。在图像周围,许多其他星系从M81星系可以被看到,以及许多前景银河系恒星。这整个星系动物园是通过一个集成通量星云(星云,IFN)发光的,它是一个巨大而复杂的气体和尘埃的屏幕,我们的银河系也是如此。红色和黄色的干扰素的细节被数码增强,是在西班牙加那利群岛的Teide天文台安装的一款新的宽视场相机成像的。
