天炉座星系团是离我们最近的星系团之一，因其南部星座而得名，其中大部分星系都可以找到。它距离我们大约6200万光年，比我们的邻居仙女座星系远20多倍，但只比更著名、人口更多的室女座星系团远10%左右。在这幅三度宽的视野中，几乎每一个黄色的斑点都是天炉座星团中的椭圆星系。椭圆星系NGC 1399和NGC 1404是最主要的明亮星团成员。一个突出的大型棒旋星系NGC 1365，在右上方是一个突出的天炉座星团成员。

Named for the southern constellation toward which most of its galaxies can be found, the Fornax Cluster is one of the closest clusters of galaxies. About 62 million light-years away, it's over 20 times more distant than our neighboring Andromeda Galaxy, but only about 10 percent farther along than the better known and more populated Virgo Galaxy Cluster. Seen across this three degree wide field-of-view, almost every yellowish splotch on the image is an elliptical galaxy in the Fornax cluster. Elliptical galaxies NGC 1399 and NGC 1404 are the dominant, bright cluster members toward the bottom center. A standout, large barred spiral galaxy, NGC 1365, is visible on the upper right as a prominent Fornax cluster member.
