⭐ 暗能量 dark energy
Nearly 200 researchers from the NAOC and the DESI jointly observed galaxies and analyzed the data over the past six years. They stitched together the observed images and formed a giant 2D map of the universe. The map covers half of the sky, digitally sprawls over 10 trillion pixels and contains about 2 billion objects.
Astronomical observations reveal that the universe is expanding and appears to be accelerating. The power driving the expansion is called dark energy by astronomers. Dark energy accounts for about 68 percent of the universe and remains a mystery.
经国家天文台和DESI国际合作团队近200名科研人员的不懈努力，历时6年进行联合观测和数据分析，对观测的图像拼接，打造了巨幅宇宙二维地图。该天图覆盖的天空面积约为全天球面积的一半，容纳了10万亿数码像素，包含了20亿天体。
天文观测研究发现，宇宙在不断地膨胀，而且处于加速膨胀状态。驱动宇宙膨胀的力量被天文学家称为暗能量。暗能量至今还是一个谜团，它占宇宙组成约68%。

#来沈阳打卡吧# #晒晒你拍的沈阳# Why should you go far to see the desert? There is a desert in Shenyang! Leaving from Shenyang’s city center, driving northward, after about two hours of travel, you will see the endless desert. It is the only national-level desert park in Liaoning, the Jinshatan National Desert Park in Kangping County.
