SETI Expands Alien Search to Over 1,300 Galaxies Using Low Radio Frequencies

New study leverages the Murchison Widefield Array to explore uncharted frequencies in search for extraterrestrial signals.

Researchers focused on a 30-degree field in the constellation Vela, encompassing 2,880 galaxies.
The study targeted low radio frequencies between 80–300 MHz, a relatively unexplored range for SETI.
No extraterrestrial signals were detected, but the search set new constraints on transmitter power requirements.
The findings will guide future studies in the search for advanced extraterrestrial civilizations.
This initiative marks a significant step in expanding SETI's search beyond the Milky Way.
