HERMES

The $13 million High Efficiency and Resolution Multi-Element Spectrograph (HERMES) is the latest major instrument for the AAT. Building upon the two degree field (2dF) system, it provides a unique and powerful new facility for multi-object astronomy. With HERMES, astronomers can analyse light from 400 stars simultaneously and will obtain spectra of more than a million stars in the Milky Way Galaxy through the ‘Galactic Archaeology‘ (GALAH) Survey.

HERMES was officially launched in April of 2014 by Department of Industry Minister Ian Macfarlane. In his speech, he stated that “Australia is a world leader in astronomy. This new instrument will allow some of our greatest scientists to make new breakthroughs in this important field.”

The primary HERMES science project is the GALAH, which aims to reconstruct the history of our Galaxy's formation from precise multi-element abundances of 1 million stars derived from HERMES spectra.
