對有些人來說,這個星雲看起來像魚頭。然而,這個色彩斑斕的宇宙肖像真正的特徵是仙后座北部一個恆星形成區 IC 1795 中的發光氣體和遮蔽塵埃雲。星雲的顏色是透過採用哈勃調色盤,將氧、氫和硫原子的窄帶發射對映成藍、綠和紅三色,再將資料與透過寬頻濾光片記錄的該區域的影像進一步融合而形成的。IC 1795 與著名的英仙座雙星團相距不遠,它本身就位於 IC 1805 (即心臟星雲)的旁邊,是位於大型分子云邊緣的恆星形成區群落的一部分。這個較大的恆星形成區距離銀河系的英仙旋臂只有 6000 多光年。在這個距離上,IC 1795 的直徑約為 70 光年。 開放科學:瀏覽天體物理學原始碼庫中的 3 , 300 多個程式碼
原文: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
