歐洲太空總署宣佈一項研究星系演化的新太空任務
ESA Announces New Space Mission to Study Galaxy Evolution

歐洲太空總署（ESA）的歐幾里得任務正在徹底改變我們對宇宙的認識。
The European Space Agency's (ESA) Euclid mission is revolutionizing our understanding of the cosmos.
自2023年7月發射以來，歐幾里得太空望遠鏡一直在距離地球150萬公里處的優勢位置運作，充當強大的時光機器。
Since its launch in July 2023, the Euclid space telescope has been operating from a vantage point 1.5 million kilometers from Earth, acting as a powerful time machine.
透過觀測距離遠達100億光年的星系光線，它讓天文學家得以回溯時光，見證宇宙如何演化成熟。
By observing light from galaxies up to 10 billion light-years away, it allows astronomers to look back in time and witness how the universe matured.
歐幾里得的首要目標是繪製「黑暗宇宙」，具體研究支配太空結構與膨脹的暗物質與暗能量。
Euclid’s primary goal is to map the 'dark Universe,' specifically investigating dark matter and dark energy, which dictate the structure and expansion of space.
然而，它也已成為研究星系演化的關鍵工具。
However, it has also become an essential tool for studying galaxy evolution.
與依賴小樣本的過往任務不同，歐幾里得提供龐大的統計數據，捕捉數百萬個星系的高解析度影像。
Unlike previous missions that relied on small samples, Euclid provides massive statistical data, capturing high-resolution images of millions of galaxies.
這使科學家能夠追蹤星系如何從活躍、正在形成恆星的系統演變為巨大的橢圓結構。
This enables scientists to track how galaxies transform from active, star-forming systems into massive elliptical structures.
發現數千個通常被稱為大型結構「建構基石」的隱藏矮星系，更增進了我們對於星系如何成長的知識。
The discovery of thousands of hidden dwarf galaxies, often called the 'building blocks' of larger structures, further enhances our knowledge of how galaxies grow.
透過連結無形力量與可見宇宙結構之間的鴻溝，歐幾里得正帶領天文學進入一個新的黃金時代，提供了宇宙歷史的全面地圖。
By bridging the gap between invisible forces and visible cosmic structures, Euclid is ushering in a new golden age of astronomy, providing a comprehensive map of the universe's history.
