The Kepler space telescope measures the sizes and ages of stars five times better than any other means - when it "listens" to the sounds they make.
Bill Chaplin, speaking at the AAAS conference in Washington, said that Kepler was an exquisite tool for what is called "astroseismology".
The technique measures minuscule variations in a star's brightness that occur as soundwaves bounce within it.
The Kepler team has now measured some 500 far-flung stars using the method.
