The COBE microwave map shown in the figure below seems to indicate that one part of the sky is 0.003 K warmer than the other.What is the cause of such an apparent anisotropy?
A) Earth and the Sun are moving at 368 km/s relative to the CMB reference frame.
B) The map was obtained when the Sun was at its peak of activity within a given 11-year cycle.
C) It is due to interference from the many microwave ovens people use in homes.
D) The boundaries between the warmer and cooler areas are sites of strong supernova activity.
E) It indicates that galaxies could form in only half of the universe.
