Minisurvey and First Results!


This weekend Planck should be moving from performance verification phase and into observations that are closer to full scale operations with the start of a minisurvey that will be very similar to (indeed, if all goes well, part of) the main all sky survey.

Meanwhile, the very first results from Planck have been presented at the International Astronomical Union General Assembly in Rio. These show a few scans around the sky and demonstrate Planck’s ability to detect the CMB ‘dipole’, which is due to Planck’s motion relative to the CMB frame of reference (this motion is due to the motion of Planck around the sun, the sun around the galaxy and of the galaxy relative to the background).

Sadly I don’t have any pictures of this yet as none have been released, but hopefully we will get something we can show you before long.
