Across 10 Million Stars, Not a Single Whisper of Alien Technology

Sep 8, 2020

In a comprehensive search of a patch of the Southern sky, not even a hint of alien technology has been detected at low radio frequencies.

Across at least 10 million stars that populate the Vela region – the deepest and widest survey for extraterrestrial intelligence yet – the Murchison Widefield Array (MWA) in Australia found none of the technosignatures that might be expected within its range.

However, astronomers Chenoa Tremblay and Steven Tingay from the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) say their results aren’t disappointing at all.

Instead, the research shows how easy it is to conduct the search for extraterrestrial intelligence (SETI) almost incidentally, while obtaining other astrophysical observations.

One comment on “Across 10 Million Stars, Not a Single Whisper of Alien Technology”

  • Earth has been transmitting (man-made) radio signals for less than 200 years. Due to receivers becoming more sensitive and transmitters becoming more closely distributed (at least in cities) and so weaker, Earth is getting quieter as a radio source.

    So there is a window of only 200 years or so that Earth is easily found by radio. One can assume that an alien civilisation would follow a similar path, so that is a very short time period to find them in this way; that any are at the right point of technology while we are looking as astronomically unlikely.

    (Personally I think that there is definitely life out there, but finding/communicating is the problem…)
