Could you elaborate on whether the concept of an Oort cloud, which is commonly associated with our solar system's icy comets residing at its farthest reaches, applies universally to all celestial systems? Are there systems that may lack such a structure, or are there alternative phenomena that serve similar purposes in other cosmic environments? It's intriguing to ponder the extent of the Oort cloud's prevalence and its significance in shaping the dynamics of planetary systems.

The Oort cloud, if it exists, is believed to have formed during the early stages of a solar system's development, as icy planetesimals were pushed outward by the gravitational forces of the newly formed planets.

While it is widely believed that many stars may possess such a cloud, the presence of an Oort cloud is not a prerequisite for the formation of a solar system according to current models.
