A team of French scientists have successfully recreated the structure of primitive interstellar particles in their laboratory. This material is a silicate glass that contains embedded metal and suphides, and astronomers believe it's created in protostellar nebulae. The team heated up particles of olivine under high vacuum and temperatures ranging between 500 to 700ºC, and the resulting material closely matched this interstellar dust. This helps scientists understand some of the processes that occur in stellar nebulae.
