对某些人来说，这个星云看起来像鱼头。然而，这幅彩色的宇宙肖像实际上描绘了IC 1795中发光的气体和模糊的尘埃云，这是仙后座北部的一个恒星形成区。星云的颜色是通过哈勃调色板绘制的，该调色板将氧、氢和硫原子的窄带辐射映射为蓝色、绿色和红色，并进一步将数据与通过宽带过滤器记录的该区域的图像混合在一起。在离英仙座著名的双星星团不远的天空中，IC 1795本身就位于IC 1805（心脏星云）旁边，是位于大分子云边缘的恒星形成区复合体的一部分。位于6000光年远的地方，较大的恒星形成复杂的沿着我们银河系的英仙座螺旋臂蔓延。在这个距离上，IC 1795的跨度约为70光年。开放科学：浏览天体物理学源代码库中的3300多个代码

To some, this nebula looks like the head of a fish. However, this colorful cosmic portrait really features glowing gas and obscuring dust clouds in IC 1795, a star forming region in the northern constellation Cassiopeia. The nebula's colors were created by adopting the Hubble color palette for mapping narrowband emissions from oxygen, hydrogen, and sulfur atoms to blue, green and red colors, and further blending the data with images of the region recorded through broadband filters. Not far on the sky from the famous Double Star Cluster in Perseus, IC 1795 is itself located next to IC 1805, the Heart Nebula, as part of a complex of star forming regions that lie at the edge of a large molecular cloud. Located just over 6,000 light-years away, the larger star forming complex sprawls along the Perseus spiral arm of our Milky Way Galaxy. At that distance, IC 1795 would span about 70 light-years across. Open Science: Browse 3,300+ codes in the Astrophysics Source Code Library
