Many people, with visions of astronauts bounding on the lunar surface in spacesuits, believe that the Moon is an airless body.
On an airless body this gives rise to very large temperature differences.
They basked in sunlight, and grew like metal forests over the surfaces of the airless bodies above us.
If this wave of dust was expelled outwards then it should have left traces on all the airless bodies in the system.
The major moons of Uranus are airless bodies.
The effect is particularly pronounced on regolith surfaces of airless bodies in the solar system.
Their pressure suits and habitats leaked atoms, leaving ghost atmospheres around otherwise airless bodies.
Alternatively, it is possible that on an airless body such as the Moon, transient magnetic fields could be generated during large impact events.
The same material that tinted most airless bodies here?
Virtually every find has been on airless or near-airless bodies.
