The review is devoted to the analysis of the formation and evolution of streams of astrophysical objects of various natures. The stream components are destructible astronomical objects: comets, asteroids, planets, stars, star clusters, and gal„axies. Almost all of these streams are now observed. We discuss the conditions for the destruction of the original objects and for the formation and dissipation of these streams. We construct numerical models of streams generated by comets, asteroids, stars and their clusters, and galaxies in their clusters, and trace the evolution of these streams on the Hubble time scale.
