The study of cluster structures in light nuclei has become a central direction in modern nuclear physics. Experimental and theoretical investigations have revealed that many light systems, such as &sup(6)He, &sup(8)Be, &sup(12)C, and others, exhibit pronounced cluster configurations that strongly influence reaction mechanisms. Particularly striking is the structure of &sup(12)C and its excited Hoyle state, which plays a key role in astrophysical nucleosynthesis. Among light nuclei, the stable yet weakly bound nucleus is of special interest due to its Borromean character and competing cluster configurations, typically described as (*a + *a + n) or (&sup(5)He +*a). These structural features manifest themselves in decay channels, scattering processes, and transfer reactions, and they directly affect the cross sections relevant for astrophysical scenarios such as the triple-*a process and the r-process. The paper provides a comprehensive overview of theoretical and experimental approaches to nuclear clustering, emphasizes recent advances, and examines outstanding questions concerning the structure of &sup(9)Be and its significance in nuclear reactions and nucleosynthesis.
