Incomprehensive knowledge on dust is hindering our study of the universe. For example, the type Ia supernovae (SNe) cosmology requires better estimation of interstellar extinction to reduce systematic uncertainties. The extinction properties measured towards type Ia SNe suggest the properties of ext...
