蓋婭重構銀河系俯瞰圖
Gaia Reconstructs a Top View of our Galaxy

發表日期:2025-05-13
從上面看銀河系是什麼樣的?因為我們在裡面,所以人類無法獲得真實的圖片。不過,最近我們利用歐空局蓋亞任務提供的十億多顆恆星的位置資料,繪製了這樣一幅地圖。結果顯示,與其他許多螺旋星系一樣,我們的銀河系也有明顯的螺旋臂。 我們的太陽和大多數我們在夜晚看到的明亮恆星都位於其中一條旋臂上:獵戶座。蓋亞的資料證實了之前的跡象,即我們的銀河系有兩條以上的旋臂。我們銀河系的中心有一個突出的條帶。 銀河薄盤的顏色主要來自於暗色塵埃、明亮的藍色恆星和紅色發射星雲。雖然資料分析仍在進行中,但蓋亞已經在繼承任務後於今年 3 月停用。 拼圖挑戰每日天文拼圖
原文:What does our Milky Way Galaxy look like from the top? Because we are on the inside, humanity can’t get an actual picture. Recently, however, just such a map has been made using location data for over a billion stars from ESA’s Gaia mission. The resulting featured illustration shows that just like many other spiral galaxies, our Milky Way has distinct spiral arms. Our Sun and most of the bright stars we see at night are in just one arm: Orion. Gaia data bolsters previous indications that our Milky Way has more than two spiral arms. Our Galaxy's center sports a prominent bar. The colors of our Galaxy's thin disk derive mostly from dark dust, bright blue stars, and red emission nebula. Although data analysis is ongoing, Gaia was deactivated in March after a succession mission. Jigsaw Challenge: Astronomy Puzzle of the Day
