【摘要】：正在天空晴好的夜晚,最敏锐的人眼最多能观测到大约2500颗星星。而"盖亚之眼"——世界上有史以来为太空计划建造的最大像素数码相机,安装在欧洲空间局研制的"盖亚"探测器上,拥有"十亿像素阵列"的超高灵敏度,可以对银河系及其周边"数以十亿"计的恒星进行亮度和光谱"巡天"。这是一次前所未有的超大规模恒星"调查活动",最终将绘制出银河系的"三维"立体地图,并据此揭示宇宙星系的组
[Abstract]:On clear nights, the sharpest human eye can see up to 2,500 stars. And Gaia's Eye, the world's largest ever built pixel digital camera for the space program, Mounted on the "Gaia" detector developed by the European Space Agency, with a "1 billion pixel array" of ultra-high sensitivity, Luminance and spectral "surveys" of "1 billion" stars in and around the Milky way. This is an unprecedented "survey" of large stars that will eventually produce a "three-dimensional" three-dimensional map of the Milky way. Based on this, the composition of cosmic galaxies is revealed.
