美宇航局公布漩涡星系M81最新照片(M81 Galaxy is Pretty in Pink)

M81 Galaxy is Pretty in Pink 06.04.07 The perfectly picturesque spiral galaxy known as Messier 81, or M81, looks sharp in this new composite from NASA's Spitzer and Hubble space telescopes and NASA's Galaxy Evolution Explorer. M81 is a "grand design" spiral galaxy, which means its elegant arms curl all the way down into its center. It is located about 12 million light-years away in the Ursa Major constellation and is one of the brightest galaxies that can be seen from Earth through telescopes. The colors in this picture represent a trio of light wavelengths: blue is ultraviolet light captured by the Galaxy Evolution Explorer; yellowish white is visible light seen by Hubble; and red is infrared light detected by Spitzer. The blue areas show the hottest, youngest stars, while the reddish-pink denotes lanes of dust that line the spiral arms. The orange center is made up of older stars.

美国宇航局最近公布了漩涡星系M81的最新照片。这张照片是由美国的史匹哲太空望远镜，哈勃太空望远镜和星系演化探测器三架太空望远镜所拍摄图象合成得到的。

　　照片中蓝色部分是由星系演化探测器捕捉到的紫外线，显示的是星系中最年轻的恒星；红色部分是由史匹哲望远镜捕捉到的红外线，显示出M81的漩臂；黄色部分是由哈勃望远镜捕捉到的可见光，显示出星系中心的最年老的恒星。

　　漩涡星系M81距地球1200万光年，位于大熊星座内，是地球上能用望远镜观测到的最亮星系之一。

3M多的图片好清晰！！！漂亮！

这是天之文的爱好者拍的M51请大家欣赏!
