Promethium

Promethium maintains limited astronomical significance due to its extreme rarity and complexities in detection within cosmic realms. As an exceedingly scarce element, promethium is formed through nucleosynthesis processes within stars, yet its abundance remains notably low compared to other cosmic elements. Theoretically observable across certain wavelengths in the ultraviolet spectrum, detecting and studying promethium in cosmic environments poses substantial challenges due to its extreme scarcity and the inherent difficulties in identification. Its minimal and infrequent presence in interstellar space or within stars makes its contribution to observed cosmic chemical compositions negligible or undetectable.
