| Description: Microwave Sky This map of the microwave sky was produced from data taken by instruments on board COBE. The galactic center is in the middle of the map, and the plane of the Milky Way runs horizontally across the map. Color indicates Doppler shift and temperature: Blue is where the microwave background is blueshifted and appears warmer, while red is where it is redshifted and appears cooler. This Doppler shift across the sky is caused by Earth’s motion through the microwave background. The resulting variation in background temperature is quite small, only 0.0033 K above the average radiation temperature of 2.726 K Picture Stats: Views: 567 Filesize: 173.15kB Height: 900 Width: 1311 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=18778 |
