STREAMING MOTION OF GALAXIES
When the cosmic background radiation of the entire sky was surveyed
in 1977, the
radiation was shifted toward the red end of the spectrum on one side of
the sky, and toward
the blue end in the other. The entire Milky Way was "streaming"
across the sky in a motion
not related to the expansion of the Universe at a rate of 700 Kilometers
per second.
