Even more distant than the Great Andromeda Galaxy,
a couple of millions of lightyears towards the dark fields of spring's
constellations, we find a group of galaxies nicely arranged. It reflects
very well the tendency of galaxies to group to clusters and even huge "walls",
"super clusters", "bubbles", etc...
Some of these structures fit into scales so large that
they fill a considerable part of our whole theoretically observable universe.
Investigation of their structure, their distribution
and scale may unveil crucial aspects of the very first moments of our universe.
