If an observer notes a strong, distinct blue hue in a meteor, which element is likely vaporizing?
Answer
Copper
A strong blue color, especially when distinct from the green caused by magnesium or the yellow/white caused by iron, is often cited as the signature of Copper (Cu) vaporizing. Copper emissions fall into a distinct blue range of the visible spectrum under these high-energy conditions created by atmospheric entry. This specific blue hue suggests a higher concentration of copper metal within the fragment entering the atmosphere, distinguishing it from other common metallic signatures.
