Traveling to a Redshift 7 Galaxy

This animation using Hubble images takes us to a distant galaxy 13 billion light-years from the Earth. In that trip we experience how the light is bent by gravitational lensing caused by a massive cluster of galaxies Abell 2218 (the yellow galaxies), and as we make our return journey, we see how the banana-like stretched images of the galaxies are straightened out and in some cases of a very distant galaxy, bent images merge together into one.
