摘要
从天文设备和科学研究两大方面,回顾了2020年天文学热点事件和研究进展。在这一年,火星正值大冲之年,火星探测迎来新高潮,"嫦娥五号"成功实现月球挖土,"老将"阿雷西博望远镜宣告"退役","中国天眼"FAST接过接力棒,在揭秘快速射电暴产生机制方面做出贡献,LIGO/Virgo引力波探测器硕果累累,明亮的新智慧星划过北半球的天空,金星生命信号引起学界争议,eROSITA和盖亚卫星分别绘制了新的银河系精细地图等一系列天文事件精彩纷呈,重大发现层出不穷。
This paper reviews the hot astronomical events in 2020 from two aspects: Aastronomical equipment and scientific research. In 2020 Mars was at the favourable opposition, traveling to Mars came to a new climax. Many countries succeeded in sampling soil in space. The FAST took the relay baton from the Arecibo telescope, contributing to uncovering the mechanism of rapid radio bursts. LIGO/Virgo collaboration grew and grew. Neowise flitted across the northern sky. The life signals found in the atmosphere of Venus caused widespread controversy. One possible driven mechanism of the fast radio burst was observed.e ROSITA and Gaia drew precise pictures of the Milky Way.
