你见过仙女座星系吗?虽然M31在肉眼看来是一个模糊的斑点,但你看到的光已经有200多万年的历史了,这可能是你直接看到的最古老的光。这张特色照片是去年年初仙女座菌株落在瑞士阿尔卑斯山后面之前拍摄的。用自己的眼睛看到这个邻近的星系到我们的银河系可能很酷,长时间的相机曝光可以捕捉到许多微弱而惊人的细节。该图像是用同一台相机在同一位置连续拍摄的前景和背景图像的合成。最近的数据表明,我们的银河系将在几十亿年后与仙女座星系碰撞并合并。在Facebook上关注APOD:阿拉伯语,英语,加泰罗尼亚语,葡萄牙语或台湾语

Have you ever seen the Andromeda galaxy? Although M31 appears as a faint and fuzzy blob to the unaided eye, the light you see will be over two million years old, making it likely the oldest light you ever will see directly. The featured image captured Andromeda just before it set behind the Swiss Alps early last year. As cool as it may be to see this neighboring galaxy to our Milky Way with your own eyes, long duration camera exposures can pick up many faint and breathtaking details. The image is composite of foreground and background images taken consecutively with the same camera and from the same location. Recent data indicate that our Milky Way Galaxy will collide and coalesce with Andromeda galaxy in a few billion years. Follow APOD on Facebook in: Arabic, English, Catalan, Portuguese, or Taiwanese
