[漢羅] 鉛筆星雲 kah 超新星震波

這个超新星震波 用一點鐘 超過 50 萬公里 ê 速度，迵過星際空間。 Tī 這幅 有清楚細節 ê 彩色組合影像 中央，向頂懸徙動 ê 彼个薄薄光光、相纏做伙 ê 雲絲，實際上是 ùi 側邊看著 ê 發光氣體 ê 長波紋。 1840 年代 John Herschel 爵士 發現伊，所以這个看起來狹狹 ê 星雲，嘛叫做 Herschel ê 光束。 這个星雲 去予編做 NGC 2736，伊尖尖 ê 外形，予伊提著鉛筆星雲 ê 現代名。 鉛筆星雲 差不多 tī 800 光年遠 ê 所在。 伊差不多有 5 光年長，是 船帆座超新星殘骸 足細 ê 一部份。 這个 足大 ê 船帆座殘骸 ê 直徑差不多有 100 光年長，是人類 tī 1 萬 1000 年前看著 ê 恆星 爆炸 湠出去 ê 殘骸雲。 爆炸 震波 就成做這个 鉛筆星雲。 上開始 ê 時陣，伊 ê 速度是一點鐘 幾若百萬公里。 毋過等伊 kā 四箍圍仔 ê 星際物質掃予清氣了後，伊 ê 速度就變較慢矣。

[English] The Pencil Nebula Supernova Shock Wave

This supernova shock wave plows through interstellar space at over 500,000 kilometers per hour. Centered and moving upward in the sharply detailed color composite its thin, bright, braided filaments are actually long ripples in a cosmic sheet of glowing gas seen almost edge-on. Discovered in the 1840s by Sir John Herschel, the narrow-looking nebula is sometimes known as Herschel’s Ray. Cataloged as NGC 2736, its pointed appearance suggests its modern popular name, the Pencil Nebula. The Pencil Nebula is about 800 light-years away. Nearly 5 light-years long it represents only a small part of the Vela supernova remnant though. The enormous Vela remnant itself is around 100 light-years in diameter, the expanding debris cloud of a star that was seen to explode about 11,000 years ago. Initially, the section of the shock wave seen as the Pencil nebula was moving at millions of kilometers per hour but has slowed considerably, sweeping up surrounding interstellar material.
