Except for the few stars in the foreground (which are bright and easily recognizable because only they have diffraction spikes), every speck of light in the composite photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 2 trillion galaxies.[1] From the Hubble eXtreme Deep Field.

An old diagram showing the location of the Local Group, including the Solar System, within the Virgo Supercluster, revealing its location at the supercluster's outskirts with the Virgo Cluster forming its heart.[2] The Fornax Cluster shown at the left was later revealed to be a separated part of the Southern Supercluster. Both superclusters are part of the greater Laniakea Supercluster cocoon (see below).

In this schematic diagram, time passes from left to right, with the universe represented by a disk-shaped "slice" at any given time. Time and size are not to scale. To make the early stages visible, the time to the afterglow stage (really the first 0.003%) is stretched and the subsequent expansion (really by 1,100 times to the present) is largely suppressed.
