Clusters of galaxies are the largest gravitationally bounded structures in the Universe dominated by dark matter. We review the observational appearance and physical models of plasma structures in clusters of galaxies. ... The knowledge of the complex dynamical and feedback processes is necessary to understand the energy and matter balance as well as to constrain the role of the non-thermal components of clusters. ...

ASTRONOMY . ASTRONOMY is a science, which studies solids and occurrences in the sky. ... They built the picture of the world according to their knowledge. With the course of time the world picture was being changed because there appeared new facts and information and new theories on the celestial occurrences and what is more impotant there appeared an opportunity to check up the correctness of ideas through the observation and measuring using the new achievements of the sciences. ...
