[漢羅] NGC 7293：捲螺仔星雲

Tī 水瓶座 方向 700 光年遠 ê 所在，有一粒 類太陽恆星 已經行到性命上尾 ê 坎站矣。 伊 tī 上尾幾若千年 ê 時間內底，產生 捲螺仔星雲 (NGC 7293)。 這是一个足濟人研究 ê 厝邊 行星形星雲，因為伊是恆星演化 上尾階段 ê 典型代表。 這攏總開 90 點鐘久 ê 時間感光，才有法度產生 這張闊幅 ê 星雲相片。 Kah 狹頻影像資料敆做伙了後，你 to̍h 會當看著 捲螺仔星雲 較光 ê 內底區 差不多 3 光年以內 ê 明顯 細節。 狹頻影像資料 ê 水素原子發射線是紅色 ê，酸素原子發射線是青藍色 ê。 捲螺仔星雲中心 ê 白點，是行星形星雲 高溫 ê 中心恆星。 拄開始看著 這个星雲 ê 時陣，咱叫是講伊是一个真簡單 ê 星雲。 毋閣咱這馬知影捲螺仔星雲有異常 複雜 ê 幾何結構。

[English] NGC 7293: The Helix Nebula

A mere seven hundred light years from Earth, toward the constellation Aquarius, a sun-like star is dying. Its last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution. A total of 90 hours of exposure time have gone in to creating this expansive view of the nebula. Combining narrow band image data from emission lines of hydrogen atoms in red and oxygen atoms in blue-green hues, it shows remarkable details of the Helix’s brighter inner region about 3 light-years across. The white dot at the Helix’s center is this Planetary Nebula’s hot, central star. A simple looking nebula at first glance, the Helix is now understood to have a surprisingly complex geometry.
