[漢羅] 有雙極 ê 龍卵發射星雲

恆星是按怎形成這个美麗 ê 星雲？ 發射星雲 NGC 6164 ê 中央是一粒 質量特別大 ê 恆星。 這粒恆星，捌去予比做 蚵仔 ê 真珠 抑是 阿拉神話內底 ê 天龍 保護 ê 卵。 咱會當 tī 相片 中央看著這粒 編號 HD 148937 ê 恆星，伊 ê 溫度懸甲會發出 紫外光，會予邊仔氣體 ê 溫度變較懸。 這款氣體應該是進前 ùi 恆星擲出來--ê，可能是 kah 踅伊咧行 ê 星伴 產生 重力交互作用 ê 結果。 擲出來 ê 物質可能去予大質量恆星 ê 磁場 搝牢咧，落尾 形成對稱 ê 雙極星雲。 NGC 6164 ê 闊度差不多有 4 光年 大，就 tī 南天星座 矩尺座 方向，離咱有 3600 光年遠。

[English] Dragon's Egg Bipolar Emission Nebula

How did a star form this beautiful nebula? In the middle of emission nebula NGC 6164 is an unusually massive star. The central star has been compared to an oyster's pearl and an egg protected by the mythical sky dragons of Ara. The star, visible in the center of the featured image and catalogued as HD 148937, is so hot that the ultraviolet light it emits heats up gas that surrounds it. That gas was likely thrown off from the star previously, possibly the result of a gravitational interaction with a looping stellar companion. Expelled material might have been channeled by the magnetic field of the massive star, in all creating the symmetric shape of the bipolar nebula. NGC 6164 spans about four light years and is located about 3,600 light years away toward the southern constellation Norma.
