About

The universe underwent an inflationary period of expansion. From an extremely hot beginning, it cooled down then reheated to form the expanding universe that we observe today. The relic radiation generated the fossil glow of the cosmic microwave background radiation, a testament to its fiery origin. Microwave telescopes map out the structure of the universe long before the galaxies were present, only 370,000 years after Big Bang. The current challenges in cosmic microwave background astronomy will be described.
