Planck Data Archive

The Planck Data Archive is an online repository that stores and provides access to data collected by the Planck satellite, a space observatory launched by the European Space Agency. Its primary mission was to map the universe's oldest light, known as the Cosmic Microwave Background (CMB), helping scientists study the universe's origins, composition, and evolution. The archive allows researchers to download detailed measurements and images, enabling analysis and discoveries about the universe’s fundamental properties and history. It serves as a valuable resource for the scientific community, supporting ongoing research in cosmology.
