The 3 alpha-reaction is one of the key reactions in nuclear astrophysics. Since it is a three-body reaction direct measurement is impossible, and therefore the reaction rate must be estimated theoretically. In this contribution I will discuss uncertainties in this reaction rate both at very low temperatures, temperatures typical for Helium burning in red giant stars, and for very high temperatures.
