    A massive star -- 10 times the mass of the Sun -- called V1449 Aquilla, turns out to have oscillations similar to the Sun. The observations were obtained over 150 days with the Convection, Rotation and Planetary Transits (CoRoT) satellite. No other massive star is known to have such oscillations, and the striking similarity to the Sun helps us study the Sun and understand the precursors to supernovae eruptions.
