A giant telescope pointed at Earth's centre

The facility operates two sophisticated arrays. One consists of 24 seismometers detecting vibrations through Earth, the other eight infrasound sensors picking up ultra-low-frequency sound waves inaudible to human ears.

Located 37km southeast of Tennant Creek — or Jurnkkurakurr, as it's known in the local Warumungu language — Warramunga consists of what might generously be called a demountable building, surrounded by sensors lined up across 20km of savannah, covered by red soil and long, white spinifex grass.
