说明: 这个星系有何特殊之处? 几乎没有,也因此西班牙舞者星系[10](NGC 1566[11])是天空中最典型和最上镜头的螺旋星系[12]之一。 不过,这幅星系影像[13]倒是有一些特别之处,因为它是两张照片以对角线并接:左上角的来自哈伯太空望远镜[14],右下角的则是韦伯太空望远镜[15]的照片。 摄于紫外光[16]波段的哈伯影像[17],突显这个星系壮观旋臂上的明亮泛蓝恒星[18]及暗色尘埃[19]所在的位置。 作为对比、摄于红外光[20]波段的韦伯影像[21],突显这些相同的尘埃[22]发出的光多于所吸收的。 而另一幅切换的影像,则呈现了这些影像其余的半边。 于2张影像之间切换,可显示那些恒星[23]在紫外光波段格外明亮,因此特别炽热;此外,还可区别看似空无一物的空间[24]和会散发红外光的尘埃。
