You are interested in how stars form – how do you look at that? “Stars form within really massive clouds of dust and plasma (a type of ionised gas) in space. We use the observations that telescopes make of these star-forming regions to help us build computer models of the typical characteristics of these clouds, such as their density, temperature, viscosity, turbulence and magnetic fields.
