Interesting facts

  • The local storage system in Galaxy has the same capacity as 6400 DVDs.
  • Galaxy is dedicated to radio-astronomy research, including processing data from SKA pathfinder projects.
  • The cabinet artwork on Galaxy, ‘Rainbow Serpent and Moon’ by Jesse Pickett, is an homage to the Centre’s close connection to the north-west of Western Australia. It has been designed to reflect ‘the sky above’, in reference to radio-astronomy, one of the areas of science iVEC supports most closely.
