5. This cosmic microwave background radiation, they said, represents the ancient afterglow of the big bang.

6. Fluctuations in the cosmic microwave background radiation probe the earliest moments of the universe.

7. However, measurements of the cosmic microwave background radiation temperature suggest that its structure may have some systematic order.

8. These gases scatter light from the cosmic microwave background radiation as it passes through the clusters, similar to the way Earth's atmosphere can scatter starlight, making some stars twinkle.

14. The influx of energy would help explain the microwave background radiation.

15. In particular, why is the temperature of the microwave background radiation so nearly the same when we look in different directions?

16. Regular checks by it's own monitoring team show only normal background radiation levels.

17. This leaves the problem of how to explain the microwave background radiation.
