是什麼激發了心臟星雲？首先，左上方的大型發射星雲被編入 IC 1805 ，看起來有點像人的心臟。 星雲中最主要的元素--氫發出的紅光非常耀眼，但這張長時間曝光的影像還混合了硫（黃色）和氧（藍色）發出的光。 在心臟星雲的中心，是來自梅洛特 15 開放星團的年輕恆星，它們正在用原子激發的高能光和風侵蝕著幾個風景如畫的塵柱。心星雲位於仙后座方向大約 7500 光年遠的地方。 這幅寬視場影像顯示了更多的內容，包括位於心星雲下方的魚頭星雲、左下方的一顆超新星殘骸，以及影像右側的三個行星狀星雲。 這幅照片歷經 57 個夜晚拍攝而成，深度很深，可以清晰地看到較暗的長而複雜的細絲。
原文：What excites the Heart Nebula? First, the large emission nebula on the upper left, catalogued as IC 1805, looks somewhat like a human heart. The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by sulfur (yellow) and oxygen (blue). In the center of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their atom-exciting energetic light and winds. The Heart Nebula is located about 7,500 light years away toward the constellation of Cassiopeia. This wide field image shows much more, though, including the Fishhead Nebula just below the Heart, a supernova remnant on the lower left, and three planetary nebulas on the image right. Taken over 57 nights, this image is so deep, though, that it clearly shows fainter long and complex filaments.
