Star Gazing Seismology of stars provides a unique insight into physical mechanisms taking place in their interior. Like the Sun, some stars have low-amplitude pulsations that are excited by turbulent convection in their outer layers. Belkacem et al. (p. 1540 ), using data gathered by the CoRoT satellite, report on low-amplitude, solar-like oscillations in a massive star that undergoes radial pulsations as a result of expanding and contracting layers in its interior. The finding opens the possibility of probing the interiors of this type of massive star, which can be the progenitors of supernovae.
