[漢羅] 紅外線波段 厚塗粉 ê 七姊妹仔星團

這敢真正是彼个有名 ê 昴宿星團？ 昴宿星團 上有名 ê 標誌是伊 ê 藍色恆星，這張圖是伊 ê 紅外線 影像，伊週邊 ê 塗粉是比內底 ê 恆星閣較光。 這張影像是 kā 三款紅外線信號 漆做 咱看有 ê 色彩（紅色 24 micron，青色 12 micron，藍色 4.6 micron）。 底圖是 NASA ê 軌道衛星，闊幅紅外線巡天探測衛星 (WISE) 太空船 翕--ê。 昴宿星團 ê 編號是 M45，偏名叫做 七姊妹仔星團。 無拄好，這馬伊 ê 頭前 有雲飄過。 昴宿星團內底 ê 大質量恆星發出 ê 光 kah 風 會 kā 細粒 塗粉粒 歕走，賰 ê 塗粉會裂開，變做 雲絲，就像圖按呢。 昴宿星團 就 tī 金牛座 ê 方向，離咱差不多有 450 光年遠。 照這个距離來估算，這張影像差不多有 20 光年 闊。

[English] Seven Dusty Sisters in Infrared

Is this really the famous Pleaides star cluster? Known for its iconic blue stars, the Pleaides is shown here in infrared light where the surrounding dust outshines the stars. Here three infrared colors have been mapped into visual colors (R=24, G=12, B=4.6 microns). The base images were taken by NASA's orbiting Wide Field Infrared Survey Explorer (WISE) spacecraft. Cataloged as M45 and nicknamed the Seven Sisters, the Pleiades star cluster is by chance situated in a passing dust cloud. The light and winds from the massive Pleiades stars preferentially repel smaller dust particles, causing the dust to become stratified into filaments, as seen. The featured image spans about 20 light years at the distance of the Pleiades, which lies about 450 light years distant toward the constellation of the Bull (Taurus).
