Following the path from Earth Guide, Nikon has decided to build a website that help us to put the all universe in perspective. It's hard to explain the concept, so here it is the explanation from the website itself:

We are able to view all entities, from the microworld to the universe, from a single perspective. By setting them up against a scale, we are able to compare and understand things which cannot be physically compared

It's an amazing experience, so try it out here and enjoy.
