我们银河系的心脏和灵魂位于仙后座吗？可能不是，但在那里可以找到两个明亮的发射星云，昵称为心脏和灵魂。心形星云，官方命名为IC 1805，在右上方的特色图像中可以看到，它的形状让人想起经典的心形符号。这种形状也许很适合情人节。灵魂星云的官方编号为IC 1871，在左下方可见。这两个星云在充满能量的氢的红光下发出明亮的光芒，这是这张三色蒙太奇中三种颜色之一。光从这些星云到达地球需要大约6000年的时间，这些星云的跨度大约为300光年。对恒星和星团的研究，比如在心脏和灵魂星云中发现的那些，主要集中在大质量恒星是如何形成的，以及它们如何影响它们的环境。

Is the heart and soul of our Galaxy located in Cassiopeia? Possibly not, but that is where two bright emission nebulas nicknamed Heart and Soul can be found. The Heart Nebula, officially dubbed IC 1805 and visible in the featured image on the upper right, has a shape reminiscent of a classical heart symbol. The shape is perhaps fitting for Valentine's Day. The Soul Nebula is officially designated IC 1871 and is visible on the lower left. Both nebulas shine brightly in the red light of energized hydrogen, one of three colors shown in this three-color montage. Light takes about 6,000 years to reach us from these nebulas, which together span roughly 300 light years. Studies of stars and clusters like those found in the Heart and Soul nebulas have focused on how massive stars form and how they affect their environment.
