About the Image: this is a map of cosmic background radiation,
the leftovers from the big bang, the zero-time point of our universe.
The yin-yang image is actually a doppler-effect artifact of
the motion of our galaxy projected into an elliptical sky map, which
doesn't lessen its sense of wonder.
An image adjusted for the doppler effect can
be viewed here.
