摘要 (Abstract): 

Since its launch in 1990, the Hubble Space Telescope (HST) has revolutionized our understanding of the universe during its 33 years in orbit. However, HST is likely to stop operating in the next few years, and its role in the ultraviolet and optical astronomy is expected to be replaced by the China Space Station Telescope (CSST). In this talk, I will briefly introduce HST and CSST, and then focus on the Multi-Channel Imager (MCI) payload of CSST. As one of the first five payloads of CSST, MCI is jointly developed by Shanghai Astronomical Observatory and Shanghai Institute of Technical Physics. It is similar to the design of the WFC3 of the Hubble Space Telescope but has its unique advantages. I will introduce the design, research status, and main scientific objectives of MCI, focusing on its scientific examples and preparations in the fields of exoplanets, stars, galaxies, etc.
