[漢羅] IC 1795：魚頭星雲

對一寡人來講，這个星雲看起來敢若是一粒 魚 頭。 毋過，這个彩色 ê 宇宙肖像 其實是 IC 1795 內底 ê 發光氣體 kah 閘光 ê 塗粉雲。 IC 1795 是一个 tī 仙后座 北方 ê 恆星形成區。 這个星雲 ê 色水是採用 哈伯色盤 ê 色。 是共酸素、水素、kah 硫磺原子 ê 狹頻發射線，對應到 藍色、青色、kah 紅色去。 閣共闊頻濾鏡 tī 這區紀錄 ê 資料濫入去，才變做這張影像。 IC 1795 tī 天頂 kah 英仙座內底彼个有名 ê 雙星團 無蓋遠，就 tī 心臟星雲 IC 1805 邊仔，是大型分子雲邊緣 ê 恆星形成區複合體 ê 一部份。 這个大型恆星形成複合體離咱才 6000 光年 遠，伊是綴咱銀河系 ê 英仙座捲螺仔手骨咧行。 照這个距離來估算，IC 1795 ê 闊度 差不多是 70 光年闊。

[English] IC 1795: The Fishhead Nebula

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.
