Herschel opened its infrared eyes

On 14 June 2009 PACS obtained images of M51, the 'Whirlpool Galaxy' in its first test observation immediately following cryo-cover opening. The images, obtained at 70, 100 and 160 microns are shown below and demonstrate that the optical performance of Herschel and its large telescope is meeting their high expectations.
