At a distance of 130 pc, CrA is one of the closest regions known to be actively forming stars, particularly within its embedded association, the Coronet. Using the Spitzer data, we identify 51 young stellar objects (YSOs) in CrA which include sources in the well-studied Coronet cluster as well as sources distributed throughout the molecular cloud.

Based on these YSO candidates, the star formation rate is computed to be 12 M sun Myr-1, similar to that of the Lupus clouds.
