Fine Structure

When we last heard from Planck, the newest investigator of the cosmic microwave background, it had started taking data mid-august. Now, just a month later, the first images from Planck are available for everyone to see.

The way in which Planck takes pictures might seem a little strange from the first picture - it's sort of a curvy ribbon of data over the entire sky - but the informational video about how Planck rotates to eventually image a 360?? area clears things up.
