The picture is pretty large, so I will just include a link: http://www.esa.int/images/FIRST_LIGHT_SURVEY.jpg
Source: ESAESA's Planck microwave observatory - the first European mission designed to study the Cosmic Microwave Background, the relic radiation from the Big Bang - started regularly surveying the sky from its vantage point at L2 on 13 August 2009. Prior to this the two instruments of this modern day 'time machine' had been fine-tuned for optimum performance. Both instruments have demonstrated excellent characteristics so far, fulfilling expectations from ground tests. In preparation for routine scientific operations, their long-term stability has been verified by conducting a first 'trial' survey – the First Light Survey.
