Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. The blotchy structures it detected are seen above in the sharpest yet picture of the universe at an early age , perhaps a mere 300,000 years old. The false-color image shows subtle fluctuations in the temperature of the hot plasma which filled the universe before expansion cooled the material, producing the familiar stars and galaxies. A flat universe will expand forever and two light rays which start out parallel will never spread or intersect.
