It may be like looking for a single leaf in a dark forest, but by doing this work in conjunction with other science and and astrophysical investigations, the cosmos is slowly revealed to us. On Sept. 2, researchers published a "breakthrough" which could help narrow the search for intelligent life in our home galaxy, the Milky Way.
The study, published in Publications of the Astronomical Society of Australia on Monday, details a search for extraterrestrial intelligence (SETI) using the Murchison Widefield Array (MWA), a collection of 4096 antennas planted in the red soil of Western Australia that detects radio signals from space.
If you have "discover an alien civilization" on your 2020 bingo card, you’re going to have to wait a little longer to cross it off. 231"}’ section="annotation">sky looked into the dark forest of the cosmos, examining over 10 million stars, but failed to turn up any evidence of alien technologies.
The search for extraterrestrial life "piggy-backs" on other work studying this region to understand the life cycle of stars.
Because the search for life is performed in conjunction with other science experiments, Tremblay says "where we go next will depend on the other science".
While the survey was able to capture over 10. 3 million stellar sources and contained six known exoplanets (likely many more exist in the region), the team notes it was like trying to find something in an ocean, but only studying "a volume of water equivalent to a large backyard swimming pool".
