A long time ago in a galaxy not so far away…

Australian National University breakthrough in galactic archaeology.

Reconstructing the history of our Galaxy has just become a whole lot easier, thanks to a team of international astronomers led by Dr Luca Casagrande from the Research School of Astronomy and Astrophysics.
By examining both the light and sound waves from stars, the team has developed a more precise way to deduce the ages of stars and to pinpoint when our Galaxy’s big events happened.
The development will help astronomers study the properties of ancient stars and help them better understand the formation and evolution of the Milky Way.
