背景星系
例句
background galaxies are visible through the faint outer arms.透过淡淡的外缘螺旋腕可以看见背景星系。Intriguing background galaxies are scattered around the field that also includes spiky foreground stars.在这个范围内还散布着引人入胜的其它背景星系，还包括道钉状的前景恒星。
The background galaxies are about one tenth the apparent size of NGC 7331 and so lie roughly ten times farther away.背景星系的大小大约是NGC7331表面大小的十分之一，而距离上则大约是10倍甚至更远。
