Our Changing World - Music of the Stars

From Jesse Mulligan, 1–4pm, 3:35 pm on 23 September 2010

They sing, they swing and they rock'n'roll - many stars, including our own sun, vibrate like a drum or a string that has been plucked. This 'music of the spheres' allows astronomers to probe the insides of stars, a part of the universe that has so far remained largely unobserved. Veronika Meduna meets University of Canterbury astronomer Karen Pollard and her team to listen to some celestial tunes and to find out why it is so difficult to explore the insides of stars.
