dust grain models

Dust grain models describe the tiny particles found in space, like those in interstellar clouds. These models help scientists understand the composition, size, and structure of dust grains—often made of materials like silicates, carbon, or ices—that influence how light interacts with space. By studying these models, researchers can better interpret astronomical observations, such as how starlight is absorbed and scattered. This understanding informs our knowledge of star formation, galaxy evolution, and the chemical processes occurring in the universe, making dust grains key to unlocking cosmic mysteries.
