Observable Universe

Jump to the observable-universe scale in Googolstars. This route opens the largest 3D view, from nearby superclusters toward the edge of what light has had time to reach us from.

• The observable universe is limited by the age of the universe and the speed of light.
• The view connects the Laniakea scale to the farthest cosmic structures shown in Googolstars.
• This page gives the deep link its own canonical URL instead of relying on the home-page fallback.
• Laniakea is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies. It spans 520 million light-years and illustrates the large-scale structure of the universe.
