Light scattering by small particles is a fundamental process in the atmospheres of the planets, in comets and interstellar clouds, affecting the radiative balance (amount of radiative energy going into and out) of a system. On Earth it is particularly important, as it affects the climate as a whole.
In this Science-Portrait planetary scientist Olga Muñoz (Instituto de Astrofísica de Andalucía, Granada, Spain) guides us into her lab and tells about the light scattering experiment she has set up and is running together with her colleagues.
