Description

After seeing beautiful images of this objet from Josh Smith and Detlef Hartmann, I had to try it myself. My image is a bit disappointing but I could not convince myself to throw away all that exposure time.

The two eyes of the smiling face are galaxies 4.5 billions light years from Earth. Their strong gravitationnal field bends space-time and distort light coming from galaxies behind.

I included an image from the Hubble Space Telescope for comparison.
