Bohrium

Bohrium is a synthetic and highly radioactive element produced exclusively through human-made nuclear reactions, with no significant presence in natural astronomical settings. Its artificial creation renders bohrium extremely scarce beyond Earth, resulting in minimal astronomical significance. Bohrium's isotopes exhibit extremely short half-lives, often lasting from milliseconds to minutes, underscoring its absence in celestial bodies or cosmic environments. The synthetic nature of bohrium confines its existence primarily to controlled laboratory conditions, such as in nuclear reactors or as a byproduct of nuclear processes.
