[漢羅] 仙王座內底 ê NGC 7822 星雲

NGC 7822 星雲內底應該是有足濟高溫少年 ê 恆星 kah 氣體塗粉做 ê 宇宙柱仔雲。 伊 to̍h tī 北天星座仙王座內底 ê 巨型分子雲邊仔,是一个離咱差不多 3000 光年遠、leh 發光 ê 恆星形成區。 這个星雲有較光 ê 邊界 kah 烏暗 ê 外形。 Tùi 這幅用 望遠鏡翕 ê 彩色天景 來講,實在是足出眾 ê。 這張影像內底有 狹頻 濾鏡 ê 觀測資料,kā 酸素原子、水素原子、kah 硫磺原子 ê 發射線,用做藍色、青色、kah 紅色色調。 發射線 kah 色光 ê 組合就是咱熟似 ê 哈伯色盤。 原子發射線 是去予恆星形成區中央 ê 高溫恆星 ê 高能輻射 kā 激發出來 ê 。 足強 ê 恆星風 kah 輻射,毋若 kā 實密 ê 柱仔雲形體 雕出來,閣 kā 修修 leh。 而且閣 tī 這个製造恆星 ê 星雲區中央,掃出一个 幾若光年闊 ê 特殊 閬空。 這个柱仔雲會因為 重力崩塌,繼續做新 ê 恆星出來。 毋閣等到柱仔雲去予侵蝕了了,to̍h 無法度 tī 這个 恆星原料場 閣製造新 ê 恆星矣。 用 NGC 7822 ê 距離來估算,這个視野差不多有 40 光年闊。

[English] NGC 7822 in Cepheus

Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and dark shapes stand out in this colorful telescopic skyscape. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red hues. The emission line and color combination has become well-known as the Hubble palette. The atomic emission is powered by energetic radiation from the central hot stars. Their powerful winds and radiation sculpt and erode the denser pillar shapes and clear out a characteristic cavity light-years across the center of the natal cloud. Stars could still be forming inside the pillars by gravitational collapse but as the pillars are eroded away, any forming stars will ultimately be cutoff from their reservoir of star stuff. This field of view spans about 40 light-years at the estimated distance of NGC 7822.
