Moscovium

Moscovium is a synthetic and highly radioactive element synthesized solely through human-made nuclear reactions, with no significant natural presence or relevance in astronomical contexts. Its artificial creation renders moscovium exceedingly rare beyond Earth, leading to minimal astronomical significance. Moscovium's isotopes exhibit extremely short half-lives, typically lasting from milliseconds to minutes, further accentuating its absence in celestial bodies or cosmic environments. Its existence remains primarily confined to controlled laboratory conditions, notably in nuclear reactors or as a result of nuclear processes.
