处女座的三角关系---NGC5566 NGC5560 NGC5569

NASA's Galaxy Evolution Explorer shows a triplet of galaxies in the Virgo cluster: NGC 5560 (bottom galaxy), NGC 5566 (middle galaxy), and NGC 5569 (top galaxy). The inner ring in NGC 5566 is formed by two nearly overlapping bright arms, which themselves spring from the ends of a central bar. The bar is not visible in ultraviolet because it consists of older stars or low mass stars that do not emit energy at ultraviolet wavelengths. The outer disk of NGC 5566 appears warped, and the disk of NGC 5560 is clearly disturbed. Unlike its galactic neighbors, the disk of NGC 5569 does not appear to have been distorted by any passing galaxies.----NASA/JPL-Caltech


NGC 5566是处女座的一个棒旋星系，距离地球约6500万光年。 这个星系是处女座星系中最大的星系，直径近15万光年。星系NGC 5566于1786年4月30日由德国天文学家威廉赫歇尔发现。

需要换个20寸RC

很皮很皮，非常皮

这星系拍摄的漂亮，高桥的镜子确实稳定。
