| + | *Planck was an ESA space telescope (2009 – 2013) that observed the cosmic microwave background (CMB) radiation. The main goal of the Planck mission was to measure small deviations from isotropy with an unprecedented accuracy and level of detail in order to distinguish between competing cosmological models. | ||
| + | Planck has released a very large number of diverse data products. | ||
