[漢羅] NGC 346 星團內底 ê 少年恆星

NGC 346 星團內底 ê 大質量恆星 ê 歲壽足短 ê，毋閣 in 足 活潑 ê。 這个星團藏 tī 小麥哲倫星雲 上大 ê 恆星形成區內底，離咱差不多有 21 萬光年遠。 恆星風 kah 輻射 tī 差不多 200 光年闊 ê 氣體 kah 塗粉雲內底，掃出一个星際閬縫，驅動 恆星形成，雕出恆星形成區實密 ê 內圍。 這个恆星形成區去 hŏng 編做 N66，伊內底嘛有足濟 嬰仔恆星。 星團內底四界攏是這寡 嬰仔恆星，in 干焦 300 到 500 萬歲爾爾，in 核心 ê 水素 猶未開始燒。 這張 Hubble 太空望遠鏡 ê 假色影像內底，可見光是藍色 ê，近紅外線是青色 ê，水素原子發射線是紅色 ê。

[English] Young Stars of NGC 346

The massive stars of NGC 346 are short lived, but very energetic. The star cluster is embedded in the largest star forming region in the Small Magellanic Cloud, some 210,000 light-years distant. Their winds and radiation sweep out an interstellar cavern in the gas and dust cloud about 200 light-years across, triggering star formation and sculpting the region's dense inner edge. Cataloged as N66, the star forming region also appears to contain a large population of [infant stars][infant stars 1]. A mere 3 to 5 million years old and not yet burning hydrogen in their cores, the infant stars are strewn about the embedded star cluster. In this false-color Hubble Space Telescope image, visible and near-infrared light are seen as blue and green, while light from atomic hydrogen emission is red.
