A new analysis of NASA's Deep Space Network finds Earth's strongest radio beams align with planetary line‑ups, boosting the chance alien civilisations could detect us and suggesting where and when we ...

What steps can be taken to identify why we haven’t received radio signals from an extraterrestrial intelligence, also called technosignatures? This is what a recent study published in The ...

Scientists may have discovered how extraterrestrial civilizations could actually detect and find Earth.

One of the longest-standing techniques in humanity’s search for life beyond Earth may be causing scientists to miss alien signals entirely, a new study finds. Since the very beginnings of the search ...

A planet's radio signal may begin as a sharp tone (left, white) but can be spread out by the star'[s surroundings plasma winds into a wider, fainter signal (right, green). The study suggests we may be ...
