WMAP (Wilkinson Microwave Anisotropy Probe) and Planck Maps are two satellite missions that were designed to study the cosmic microwave background radiation (CMB) - the leftover radiation from the Big Bang. These maps show temperature fluctuations in the CMB which can provide insights into the early universe and its evolution.
The WMAP and Planck Maps are created using data collected by the satellites' instruments. The data is then processed and analyzed using complex algorithms to produce maps of the CMB temperature fluctuations. These maps are in the form of a cartesian projection, which is a way of representing a spherical object (like the sky) on a flat surface.
The WMAP and Planck Maps provide valuable information about the age, composition, and evolution of the universe. They can also help us understand the distribution of matter and energy in the early universe, as well as the processes that shaped the universe into its current state.
The WMAP and Planck Maps provide evidence that supports the Big Bang theory. They show a nearly uniform distribution of the CMB temperature fluctuations, which is consistent with the idea that the universe was once extremely hot and dense, and has been expanding and cooling ever since.
The WMAP and Planck Maps have numerous applications in cosmology and astrophysics. They have helped us understand the origins of the universe, the formation of large-scale structures such as galaxies and galaxy clusters, and the nature of dark matter and dark energy. They have also been used to test various cosmological models and theories, and have provided valuable data for future missions and research projects.
