How did the COBE satellite take the picture?
The COBE satellite was equipped with a special instrument called the Differential Microwave Radiometer, which was designed to measure the temperature of the cosmic microwave background radiation, which is the residual heat left over from the Big Bang. By studying this radiation, scientists were able to map out the distribution of matter in the universe, including the Milky Way Galaxy.
