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. eROSITA and Gaia drew precise pictures of the Milky Way.
