Earth’s Deep-Space Transmissions: When and Where Extraterrestrials Could Detect Them

To the point

Pinchen Fan and colleagues show that Earth’s deep-space transmissions are most detectable along the ecliptic during Earth–Mars conjunctions, with about a 77% spillover chance and ~12% for other alignments, averaging roughly 23 light-years in detectable range, and Jason Wright argues SETI should focus on favorable geometry and timing while Joseph Lazio emphasizes DSN’s central role and lasers as an emerging technosignature option.
