In collaboration with the SETI Institute and the Berkley SETI Research Center, both based in the US, the International Centre for Radio Astronomy Research used the Murchison Widefield Array in remote Western Australia to search for alien life in galaxies other than our own at low radio frequencies for the first time.

The MWA is a radio telescope made up of eight thousand one hundred and ninety two antennas, spread across more than thirty square kilometers on Wajarri Yamaji land about three hundred kilometers north-east of Geraldton, designed to observe the sky and detect emissions from the early universe and to study solar and galactic phenomena.

The research team used the MWA’s wide field of view to search approximately 2800 distant galaxies, making it one of the most detailed searches for alien life ever conducted.

This first ever low-frequency extragalactic technosignature search didn’t find anything – yet – however.
