This cool image depicts the entire universe on a radial logarithmic scale. It was made by artist Pablo Carlos Budassi based on logarithmic maps of the Universe developed by Princeton researchers and a ton of NASA images. Our Sun is in the middle and the rim is the plasma created by the Big Bang.
I found this via sciencealert.com, which has a lengthier description. A full-sized version of Budassi's image can be found here and the Princeton maps are here.
