[漢羅] M82：有星系風 ê 星爆星系

M82 是一个有星系風 ê 星爆星系。 實際上，M82 內底爆發 ê 恆星形成運動，有連紲 ê 超新星爆炸 kah 大質量恆星強力 ê 恆星風，才會產生這个巨型噴流。 星系中心區 有星系風 ê 證據，to̍h tī 這个清楚 ê 望遠鏡速翕內底。 這張組合影像 kā 原子氣體 ê 長噴流絲發射光，用紅色色調 kā 強調出來。 星系風內底有一寡氣體，會 幫贊大質量恆星製造 重元素。 這寡重元素，落尾會離開恆星，走入去 星際空間。 M82 是因為 kah 附近 ê 大 星系 M81 倚傷近，才變 kah 遮爾活潑。 伊強烈 ê 恆星形成爆發階段，應該會連紲爆 1 億年左右。 因為 M82 有搝長 ê 外形，才予伊又閣叫做大管薰星雲。 伊 to̍h tī 大熊座 北爿邊仔附近 1200 萬光年遠 ê 所在。

[English] M82: Starburst Galaxy with a Superwind

M82 is a starburst galaxy with a superwind. In fact, through ensuing supernova explosions and powerful winds from massive stars, the burst of star formation in M82 is driving a prodigious outflow. Evidence for the superwind from the galaxy's central regions is clear in sharp telescopic snapshot. The composite image highlights emission from long outflow filaments of atomic hydrogen gas in reddish hues. Some of the gas in the superwind, enriched in heavy elements forged in the massive stars, will eventually escape into intergalactic space. Triggered by a close encounter with nearby large galaxy M81, the furious burst of star formation in M82 should last about 100 million years or so. Also known as the Cigar Galaxy for its elongated visual appearance, M82 is 12 million light-years distant near the northern boundary of Ursa Major.
