Blue supergiant stars open doors to concert in space

Blue supergiants are rock-and-roll: they live fast and die young. This makes them rare and difficult to study. Before space telescopes were invented, few blue supergiants had been observed, so our knowledge of these stars was limited. Astronomers have now studied the sounds originating inside these stars and discovered that almost all blue supergiants shimmer in brightness because of waves on their surface.
