Title: A deep look in the Universe using Cluster Lenses

***********************************************************
Abstract: I will discuss how massive cluster of galaxies can act as gravitational lenses. As Zwicky dreamed, these powerful gravitational lenses are very useful in studying the mass distribution of clusters and probe the distant Universe by strongly magnifying distant sources. I will present some of the latest results, related to the detection of the first galaxies in the Universe, and the prospects in discovering the first stars.
