What would the universe look like to an electron some 370,000 years after the big bang? This spring the Planck cosmology probe released a fine-scale map of the subtle thermal variations imprinted on the cosmos around that time, revealing that the universe was slightly older than previously thought. But the Planck instruments also measured the polarized intensities of the ancient light. Mission scientists are now working to zoom in using the polarization data, getting that electron’s-eye insider view of the early universe.
