Comparison of M51 imaged with the Spitzer Space Telescope (left panel) and an image of the same galaxy taken with the Herschel Space Observatory (right panel), launched just a month ago.
The obvious advantage of the larger size of the telescope is clearly reflected in the much higher resolution of the image: Herschel reveals structures that cannot be discerned in the Spitzer image. Both images were taken at the wavelength of 160 microns.
