Technology in 10 Million Star Systems
International Center for Radio Astronomy Research | 2020 Sep 08
A radio telescope in outback Western Australia has completed the deepest and broadest search at low frequencies for alien technologies, scanning a patch of sky known to include at least 10 million stars.
Astronomers used the Murchison Widefield Array (MWA) telescope to explore hundreds of times more broadly than any previous search for extraterrestrial life.
The study ... observed the sky around the Vela constellation. But in this part of the Universe at least, it appears other civilisations are elusive, if they exist.
The research was conducted by ... Dr Chenoa Tremblay and Professor Steven Tingay ... Dr Tremblay said the telescope was searching for powerful radio emissions at frequencies similar to FM radio frequencies, that could indicate the presence of an intelligent source.
These possible emissions are known as ‘technosignatures’. ...
