  The European Space Agency (ESA) recently released the first set of images captured by the Euclid space telescope. The telescope shows a spectacularly panoramic and detailed view of the Perseus galaxy cluster and the Horsehead Nebula. The €1bn mission, which launched in July, also promises to unveil the “dark universe”.
  The first images show the Horsehead Nebula in dazzling detail and capture approximately 100,000 galaxies in a single snapshot. The Horsehead Nebula is part of the constellation Orion.
  The telescope can detect galaxies out to 10bn light years and is intended to create the largest cosmic 3D map ever made. This will allow astronomers to analyze the distribution of dark matter and dark energy. Even though dark matter and dark energy make up 95% of the universe, their natures are almost entirely mysterious.
  Over the next six years, Euclid will observe about 8bn galaxies across 36% of the night sky.

 歐幾里得望遠鏡可觀測1 百億光年以外的星系,目標是繪出有史以來最大的3D宇宙地圖。這將有助於天文學家分析暗物質和暗能量的分布情況。雖然宇宙的95%是由暗物質和暗能量組成,但其性質對人類而言,幾乎完全是個謎。
 接下來的六年,歐幾里得太空望遠鏡將觀測約80 億個星系,橫跨36% 的宇宙夜空。
