Specialized Resource (Document): Distance of the Andromeda galaxy
Description
Within this use case for high school students and adanced amateurs you measure the linear distance of the Andromeda Galaxy following the steps of the astronomers who first measured it, climbing an important step of the so-called cosmic distance ladder. The use case requires the identification of variable stars of the Cepheid class and the determination of the relation between their period and their intrinsic luminosity.
