No sign of extraterrestrial life in more than 1,300 stars near Earth


For three years, an international group of scientists made an intense observation of a total of 1,327 stars close to Earth, with the aim of finding possible signs of extraterrestrial life.

This is part of the project “Breakthrough Listen”, a program of Search for Extraterrestrial Intelligence (SETI), which is directed by astrophysicist Danny Price.

The results, recently published in the journal Astrophysical Journal, indicate that no sign of the existence of advanced civilizations has been detected in other worlds.

To carry out this work, the scientists used the data collected by two of the most powerful telescopes in the world: the Robert C. Byrd of Green Bank (USA) and the Parkes Telescope in Australia.

“We analyzed thousands of hours of observations from nearby stars, through billions of frequency channels. We found no evidence of artificial signals beyond Earth,” Price said.

However, he clarified that “this does not mean that there is no intelligent life out there. It is possible that we have not yet seen it in the right place or deep enough to detect weak signals. “

With these new results, Breakthrough Listen has completed the most complete and sensitive radio search for extraterrestrial intelligence in history.

In addition, the experience gained during the first three years of the program means that Listen is ready to extend these results to higher frequencies, more types of signals and thousands of times more stars, a statement said.
