Hassium

Hassium is a synthetic and highly radioactive element primarily generated through human-made nuclear reactions, lacking significant presence in natural astronomical realms. Its synthetic origin makes hassium exceedingly rare beyond Earth, contributing to its minimal astronomical relevance. Hassium's isotopes possess extremely short half-lives, typically lasting from milliseconds to minutes, further accentuating its absence in celestial bodies or cosmic environments. Its production is confined to controlled laboratory conditions, notably in nuclear reactors or because of nuclear processes.
