MOTHERBOARD shares a University of Sydney study about the possible evolution of the Milky Way.

But while some pulsating stars beat at regular intervals, others are a little jazzier. For instance, astronomers have puzzled for years by the seemingly discordant oscillations of so-called delta Scuti stars, which are about 1.5 to 2.5 times the mass of the Sun.
