有一粒離地球干焦 700 光年遠爾爾、佇 寶瓶座 方向、太陽質量 ê 恆星,當咧死亡。 這粒欲死 ê 恆星佇這个階段持續幾若千年,製造出這个 捲螺星雲 (NGC 7293)。 伊是一个咱研究足濟 ê 厝邊 行星形星雲,是恆星演化尾期 ê 形態。 這張狹頻影像是 kā 紅色 ê 水素原子發射線 kah 藍色 ê 酸素原子發射線疊出來 ê 結果。 咱會當看著捲螺星雲足精彩 ê 細節,嘛包括 內底 3 光年闊較光 ê 區域。 捲螺星雲中心彼个白點,是佇行星形星雲中央 ê 高溫恆星。 拄開始影--著 ê 時陣,叫是講這是一个簡單 ê 星雲。 毋過這馬咱知影講,這个捲螺星雲有一个足 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 star is dying. The once sun-like star's last few thousand years have produced the Helix Nebula. Also known as NGC 7293, the cosmic Helix is a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution. Combining narrow band data from emission lines of hydrogen atoms in red and oxygen atoms in blue-green hues, this deep image shows tantalizing details of the Helix, including its bright inner region about 3 light-years across. The white dot at the Helix's center is this Planetary Nebula's hot, dying central star. A simple looking nebula at first glance, the Helix is now understood to have a surprisingly complex geometry.
