Magnetic Wave Detection Uncovers Elusive Lithium in Mercury’s Thin Exosphere

For the first time, scientists have detected lithium in Mercury’s exosphere using magnetic wave signatures found in MESSENGER spacecraft data. The findings link lithium’s release to meteoroid impacts that vaporise planetary material, offering fresh insight into volatile element delivery. This breakthrough reshapes our understanding of Mercury’s surface chemistry and thin atmospheric dynamics across airless planetary bodies

First Evidence of Lithium in Mercury’s Atmosphere Detected in Hidden Magnetic Signals

A recent breakthrough in planetary science reveals the first-ever detection of lithium in Mercury’s exosphere—a result achieved not through traditional particle observation, but through a novel method relying on electromagnetic wave analysis. Published in Nature Communications, the study led by Daniel Schmid and his team at the Austrian Academy of Sciences outlines how ion cyclotron wave signatures hidden in four years of MESSENGER spacecraft ma…
