Earth is not the only planet that has extreme weather. Mercury, our smallest planetary neighbor, has very little to call an atmosphere — but it does have morning micro-meteor showers.
In order to study these micrometeoroids, scientists combined models with findings from the MESSENGER spacecraft — short for Mercury Surface, Space Environment, Geochemistry and Ranging, a mission that observed Mercury from 2011 to 2015.
In this image, data from the Mercury Atmosphere and Surface Composition Spectrometer instrument is overlain on the mosaic from the Mercury Dual Imaging System.
