The invisible matter that builds every planet and lifeform
In short: Space is not a true vacuum. This lecture explores the microscopic grains of silicate and carbonate that float between the stars, acting as the fundamental reservoir for all planetary formation.
Professor Carolin Crawford examines the tenuous material of interstellar space, which consists of atomic gas mixed with minute grains of dust and complex molecules. These materials are detectable by observing how they scatter and absorb visible light or emit their own infrared glow.
This study of interstellar matter is essential because it serves as the primary source material for the creation of planets and the lifeforms that inhabit them.
