Another 2003 Image...

What is it? The Cosmic Microwave Background radiation. Say what? The radiation left over from the Big Bang, if the theory is true, should still permeate the entire cosmos. It should be a certain temperature, and it should have specific irregularities. This finely tuned measurement of the CMB allowed astronomers to narrow the age of the universe down to 13.7 billion years. It also allowed them to determine that the first stars were able to form only 200 million years after the bang. Finally, it provided them with additional confirmation of the amount of regular vs. dark matter in the universe. An interesting sidenote to this image... it shows the universe at approximately 300,000 years in age - the time when light was first able to separate from darkness.
