The evolution of low- and intermediate-mass stars after the end of central hydrogen burning is an important and very visible phase of the life of stars. The stars expand and become red giants, followed by the ignition of central helium burning, which leaves the star in the so-called ‘red clump’. Due to their visibility the red giants are important tracers of Galactic structure. Furthermore, this phase of evolution involves a number of complex and poorly understood physical processes. In the last few years observations from the CoRoT and Kepler spacecraft have provided unprecedented opportunities for studying the internal structure and dynamics of red giants. I shall discuss the observations and the resulting inferences, which have clarified some aspects of our understanding of the evolution of these stars but have raised other very interesting puzzles.
