Most detailed map yet of cosmic microwave background, from Planck satellite

Brief summary of findings:
1. Generally very good agreement with theory. (So, e.g., inflation is still looking good.)
2. At large angular scales (6 to 90 degrees) Planck finds slightly smaller fluctuations than best theoretical model predicts, though in their plot the theoretical curve goes within almost all the error bars.
3. New improved estimate for the Hubble constant and hence the age of the universe; Planck's estimate of the age of the universe is about 80 million years older than WMAP's had been. (WMAP's estimate was a bit lower than other data suggested, so this isn't a huge surprise.)
4. There's slightly more dark matter and slightly less dark energy than previously thought; the estimate of the amount of ordinary stuff hasn't changed.
5. Planck confirms the asymmetry and "cold spot" seen before by WMAP. (There are existing models of the universe that incorporate the sort of asymmetry Planck sees, but they don't fit the rest of the data so well.)
