It's a dusty Universe: surface science in space

摘要: We live in a dusty Universe! Dust is not only found our solar system among the planets but wide variety of objects throughout Universe, mainly those regions between stars known as interstellar clouds. Interstellar dust particles, which consist cores silicates and carbonaceous material often surrounded by icy mantles, are most probably highly irregular shape with size distribution from micro- to nanometers. important for many reasons, including template it provides surface chemical reactions that form, other species, molecule––H2. In this article, we discuss evidence dust, its physical properties, role chemistry, what remains be learned.
