Em, not quite.
First of all that's the map of the
observable universe.
Second, that's the cosmic microwave background, and I am quoting from the website where the image can be found:
"The cosmic microwave background (CMB) is an almost-uniform background of radio waves that fill the universe. The CMB is, in effect, the leftover heat of the Big Bang itself - it was released when the universe became cool enough to become transparent to light and other electromagnetic radiation, 100,000 years after its birth. At this time, the universe was filled with a hot, ionized gas. This gas was almost completely uniform, but did have slight deviations - spots that were slightly (1 part in 100,000) more or less dense. The slight changes in the intensity of the CMB across the sky (deviations of only than 1 part in 100,000) give us a map of the early universe. The picture below such a map, measured by the Wilkinson Microwave Anisotropy Probe (WMAP), a space-based microwave telescope for studying the CMB. By studying this map, astrophysicists have learned an enormous amount about the evolution and composition of the universe. " (the map below mentioned, is the picture originally posted.)
The website can be found here, if anybody is interested: http://cosmology.berkeley.edu/Education/CosmologyEssays/The_Cosmic_Microwave_Background.html
The (observable) universe
might actually look like this:
Notice the planes formed by our incomplete telescope exploration. This is a simulated picture based on current data. I don't believe we have sattelites more that billions of light years taking pictures of the universe we know
EDIT: I forgot to say that each speck of light is probably a supercluster of galaxies.. A pixel within the specks might be a galaxy, or maybe a local group of galaxies.
