New Paper on Stardust fine grained material

Our consortium on Stardust material has published a new article about primitive fine-grained materials found in comet dust. The paper, titled “Fine-grained material associated with a large sulfide returned from Comet 81P/Wild 2” (primary author Zack Gainsforth), takes a look at a large particle called Andromeda, and how it shielded this delicate material upon aerogel … More New Paper on Stardust fine grained material
