幻影星系

一个正面朝向我们的旋涡星系；Webb 的红外图像显示出它旋臂中的气体和尘埃纤维。

图片挂在该距离处，朝向地球，大小与它在天空中一样；看不出天体有多深，所以它是平的。

Messier 74 is a large spiral galaxy in the equatorial constellation Pisces. It is about 32 million light-years away from Earth. The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy. The galaxy's low surface brightness makes it the most difficult Messier object for amateur astronomers to observe.
