Odyssey Module records Earth's radio signals from Moon

American scientists from the University of California in Boulder have captured and analyzed radio signals from Earth using equipment on the "Odyssey" module located on the Moon.

As reported by Gazeta.ru, the research was presented at the annual meeting of the American Astronomical Society (AAS).

According to the experiment's lead, Professor Jack Burns, placing a radio observatory on another celestial body allowed them to view Earth as an exoplanet—a world orbiting another star.

"This allows us to ask: what would our radio emissions from Earth look like if they were coming from an extraterrestrial civilization on a neighboring exoplanet?" Burns explained.

During the project, "Odyssey" recorded Earth's radio background, emitted by cellular systems, broadcast towers, and other technological sources, for an hour and a half. The result was a data array representing a sort of "radio selfie" of our planet.

The scientist noted that the last similar experiment was conducted in the 1990s using NASA's Galileo spacecraft. The project was led by the famous astronomer, writer, and science popularizer Carl Sagan. However, "Odyssey's" information turned out to be more complete and comprehensive.

Researchers hope to conduct a second similar experiment on another lunar module, CLIPS, in 2026.
