Abstract: Understanding galaxy formation is one of the most pressing issues in cosmology. We review the current status of galaxy formation from both an observational and a theoretical perspective, and summarize the prospects for future advances.

Keywords: galaxy: formation — galaxies: evolution — galaxies: star formation — galaxies: active
