在从平流层收集的行星际尘埃颗粒中观察到顽火辉石（MgSiO3）晶须和薄片。它们独特的晶体形态和微观结构，如轴向螺旋位错，强烈表明它们是主要的气相冷凝物，可能形成于太阳星云或太阳前环境。
Enstatite (MgSiO3) whiskers and platelets have been observed in interplanetary dust particles collected from the stratosphere. Their unique crystal morphologies and microstructures, such as axial screw dislocations, strongly suggest that they are primary vapour phase condensates which could have formed either in the solar nebula or in presolar environments.
