The Full Story
In 1992, the COBE satellite team released the first detailed measurements showing tiny variations in the cosmic microwave background. These fluctuations were only a few parts in 100,000, but they were crucial because they revealed the seeds of later cosmic structure. The results supported the idea that galaxies formed from small density differences in the early universe. This was a landmark moment in observational cosmology.
