Abstract: Hubble Frontier Fields show galaxies deep in the past at red shifts up to 8. This is the time shortly after the reionization of the universe and formation of the first stars. Sizes of star forming clouds are at the level of 10 pc only, close to the dimesions of globular clusters. The early enrichment by yields of stellar evolution and dust is essential ingredient in the explanation of presence of multiple stellar generations in globular clusters. Massive star clusters form also in the local universe and I will speculate how is the early star formation producing first stars and globular clusters connected to the local star forming regions such as the Gould's belt near to the Sun.
