ngc 918 是位於白羊座的棒旋星系，它的旋臂比較鬆散，屬於 sbc 型，距離地球約六千萬光年 [1,2]。它的視大小只有 3.5 x 2角分，利用小望遠鏡拍攝，ngc 918本身很小，不甚可觀。不過在星系的背景中，可以看見絲絲縷縷的星雲，像一個巨網般包圍著星系 [3]。

It also captures NGC 918 in a cosmic moment important to astrophysicists on planet Earth. Light from supernova SN2009js, absent in previous images, is indicated by the two lines just below and left of the galaxy's center. The supernova itself is the death explosion of a massive star within the plane of galaxy NGC 918.
