[漢羅] 有恆星、氣體、kah 磁性 ê 銀河中心

咱 ê 銀河中心是發生啥物代誌？ 為著欲揣出這个答案，一个新 ê 用 電波 kah X-光翕 ê 詳細全景組合圖，會當 探索 [銀河盤][galactic plane] 面頂 kah 下跤。 這張 Chandra 踅地衛星天文台 翕 ê X-光 影像，有柑仔色（高溫），青色 (較高溫)，kah 茄仔色 (上高溫)。 閣 kah MeerKAT 陣列 翕 ê 殕色 ê 高解析度 電波 影像疊做伙。 銀河內底 ê 交互作用有足濟種，嘛真複雜。 銀河 猛獸，親像是 脹大 ê 超新星殘骸、新恆星 ê 高溫恆星風、異常強烈 ê 相碰磁場、kah 銀河中心 ê 超大質量烏洞，攏 tī 宇宙內底 1000 光年 闊 ê 範圍相戰。 較薄 較光 ê 光巡 是磁場相碰區內底 扭曲 kah 新接做伙 ê 磁場。 這會產生銀河內部 ê 太空氣候變化，to̍h kah 咱太陽產生 ê 能量形態欲仝。 繼續做觀測 kah 研究，毋若會當予咱 閣較了解 咱銀河 ê 歷史 kah 演化，嘛會當予咱了解其他 ê 星系。

[English] The Galactic Center in Stars, Gas, and Magnetism

What's going on near the center of our galaxy? To help find out, a newly detailed panorama has been composed that explores regions just above and below the galactic plane in radio and X-ray light. X-ray light taken by the orbiting Chandra Observatory is shown in orange (hot), green (hotter), and purple (hottest) and superposed with a highly detailed image in radio waves, shown in gray, acquired by the MeerKAT array. Interactions are numerous and complex. Galactic beasts such as expanding supernova remnants, hot winds from newly formed stars, unusually strong and colliding magnetic fields, and a central supermassive black hole are all battling in a space only 1000 light years across. Thin bright stripes appear to result from twisting and newly connecting magnetic fields in colliding regions, creating an energetic type of inner galactic space weather with similarities to that created by our Sun. Continued observations and study hold promise to not only shed more light on the history and evolution of our own galaxy -- but all galaxies.
