是什么让心脏星云兴奋？首先，这个被称为IC 1805的大型发射星云整体上看起来像一颗人类的心脏。它的形状也许很适合情人节，这颗心在它最突出的元素：激发态氢发出的红光中发出明亮的光芒。红色的光芒和较大的形状都是由星云中心附近的一小群恒星产生的。在心脏星云的中心是来自疏散星团Melotte 15的年轻恒星，它们正用充满活力的光和风侵蚀着几根风景如画的尘埃柱。疏散星团中有几颗明亮的恒星质量接近太阳的50倍，许多暗淡的恒星质量只有太阳的一小部分，还有一颗在数百万年前被驱逐的微类星体。心脏星云位于神话中的仙后座（仙后座）的星座，距离我们约7500光年。

What excites the Heart Nebula? First, the large emission nebula dubbed IC 1805 looks, in whole, like a human heart. Its shape perhaps fitting of the Valentine's Day, this heart glows brightly in red light emitted by its most prominent element: excited hydrogen. The red glow and the larger shape are all created by a small group of stars near the nebula's center. In the heart of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds. The open cluster of stars contains a few bright stars nearly 50 times the mass of our Sun, many dim stars only a fraction of the mass of our Sun, and an absent microquasar that was expelled millions of years ago. The Heart Nebula is located about 7,500 light years away toward the constellation of the mythological Queen of Aethiopia (Cassiopeia).
