Abstract: We studied the young star clusters and the star-forming regions in M31, with Galaxy Evolution Explorer (GALEX) imaging far-UV and near-UV. The GALEX imaging, combining deep sensitivity and entire coverage of the galaxy, provides a complete picture of the recent star formation in M31 and its variation with environment throughout the galaxy. The young star clusters distribution exhibits a distinct peak in the M31 disk around 10 - 12 kpc form the center and follow a spatial distribution similar to other tracers of disk structure. On the contrary, star-forming regions show two distinct peaks. We compared various properties (e.g., age, mass, spatial distribution) of young clusters and star-forming regions. The young clusters and massive star-forming regions might be associated with the well-known 10 kpc star formation ring structure. We suggest the occurrence of a significant recent star formation in the disk of M31.
