Travelling to a redshift 7 galaxy

Travelling to a redshift 7 galaxy

Date: 14 February 2004

If we imagine travelling to the distant galaxy 13 billion light-years from the Earth we experience up close how the light is bent by the massive cluster of galaxies Abell 2218 (yellow galaxies). In fact as we are making the opposite journey of the light, we see how the banana-like stretched images of the galaxies are straightened out and in some cases - as for the very distant galaxy - combined together to one galaxy.
