      The gold dome on my town's town hall peels off in the weather in a short time. How well will this layer of gold stand up over time in the face of solar winds or other space weather?

      Hello Glenn! You're right that pure gold is very soft. Webb's mirrors are actually protected by a thin layer of glass on top of the gold to protect them.
