Planck mission

The Planck mission was a space observatory launched by the European Space Agency to study the universe's origins. It mapped the faint microwave radiation, known as the Cosmic Microwave Background (CMB), which is the afterglow of the Big Bang. By analyzing this ancient light, Planck provided detailed information about the universe’s age, composition, and structure, helping scientists understand how the cosmos evolved over billions of years. Its precise measurements have refined our knowledge of cosmology and confirmed key theories about the universe’s early moments.
