Color variations in this WMAP image show small departures – about .00002 K – from the average CMB temperature of 2.726 K. Tiny local variations in density caused CMB photons to lose a bit more or less energy as they climbed out of slightly more or less dense regions. 🔭 🧪 Image: NASA / WMAP

In the early 90s I attended a presentation about the COBE results given at an alumni seminar, I asked if there was any correlation between the variation in the map and structure that we can see now (like galactic super clusters)… they said “we don’t know yet”…curious if that is being looked at
