It is real miracle what amount of data you can extract from spectar of light.
That is the only thing you have when you try to find out something about any object in cosmos. You can get distance, mass, chemical elements on the object, is the star a twin or it has planet system, period of rotation. Also you can find out evolution path of the star. Will it end like black hole, neutron star white dwarf...
sorry for bad english
