One of the long-standing difficulties in astrophysics has been a way to accurately determine the age of a star. Brand new stars are obvious from their location in or near "star nurseries" of interstellar gas and dust, and "adult" stars can be roughly characterized through various methods, including a calculation based on their mass and luminosity. Unfortunately, these methods are approximations at best. Researchers at KU Leuven's Institute for Astronomy have now discovered a way to distinguish young stars from older ones by measuring the acoustic waves that they emit using ultrasound technology...
