The two telescopes were Planck, which will make the most sensitive maps of the early Universe over the whole sky, and Herschel, the largest infrared space telescope ever launched. One year on, both missions are going strong and returning some fascinating new images and results.
The first scientific results (link opens in a new window) from Herschel are revealing previously unseen star formation. New images show thousands of distant galaxies furiously building stars, and beautiful star-forming clouds draped across the Milky Way.
