This research work is based on VLBI exploration of radio astrometry (VERA) with H2O (616-523) maser line emission to trace the site of star formation within the interface of W44 SNR. It also includes the study of young stellar objects in the early phase of the evolution and the effect of the expanding bubbles towards triggering the Young Stellar Objects using infrared science archival (IRSA). Our results indicated the presence of H2O maser evidencing star forming region. Further study on the region with infrared emission shows that there is an expanding bubble of W44 SNR near the identified H2O maser. Furthermore, the distributions of YSOs from the archival data in an expanding bubble of the W44 supernova remnant indicate an evolutionary sequence which starts with class III → class II → class I objects.
