The sun emits light, but it also emits particle beams. A scientist has now revealed how these beams generate radio waves. These radio waves can tell us about the outer layers of the sun and the interstellar medium without going there. In particular, the radio emissions are produced in small packages, and their shapes are determined by the density changes in the solar wind.
