WMAP ILC Seven Year Microwave Sky - Grayscale

Grayscale version -White=hot Black=cold
Seven Year Microwave Sky

The detailed, all-sky picture of the infant universe created from seven years of WMAP data. The image reveals 13.7 billion year old temperature fluctuations (shown as color differences) that correspond to the seeds that grew to become the galaxies. The signal from the our Galaxy was subtracted using the multi-frequency data. This image shows a temperature range of ± 200 microKelvin.
