Scientists of the project Breakthrough Listen, directedon the search for extraterrestrial life, published the results of the first three years of his observations. Recall that the goal of the project with a budget of $ 100 million, launched in 2015 by investor Yuri Milner and the late theoretical physicist Stephen Hawking, is to scan 1 million stars closest to us, as well as 100 neighboring galaxies located near the Milky Way.
According to the portal Space.com, the project’s scientists have so far scanned 1327 nearby stars in detail (which is 80 percent of their number) for the presence of signals from extraterrestrial technologies. In an official statement of scientists reported that it was collected almost 1 petabyte (1 million gigabytes) of digital data, which is now freely available to the public.
Aliens have not yet found
“Publishing this dataset is a huge milestonefor the Breakthrough Listen command. We have cleared thousands of hours of observations of nearby stars at billions of different frequencies. We did not find traces of artificial signals, but this does not mean that there is no intelligent life there: we could not look in the right place or look deeply enough to catch the necessary signal, ”said the leading author of the article, an employee of Swinburne University of Technology and California. University of Berkeley Danny Price.
Breakthrough Listen group fromThe University of California, SETI Research Center (BSRC) at Berkeley has developed a number of methods to search for data on “technograms” - evidence of technologies that may include, for example, transmitters or power plants created by civilizations outside the Earth. These methods include the search for powerful signals occupying a narrow range of radio frequencies, the search for bright lasers used for communication or movement, and the use of new algorithms based on machine learning methods. Their scientists use to study unexplained astrophysical phenomena in addition to searching for techno-signatures.
To search for aliens scientists usethe Green Bank radio telescope, located in West Virginia (USA), as well as the Parks radio telescope in Australia. Soon planned to connect to the project and other observatories.
The research results of the first three years of workof the project are publicly available on the Breakthrough Listen website and on the BSRC website. The database with a total size of 1 petabyte also contains the results of observations of the first repeating fast radio burst of FRB 121102 and the Oumuamua asteroid.
“Although we have previously reported less extensivethe results of our work, we are pleased to announce that we are ready to provide in open access the first full and very large collection of data, as well as instructions with which anyone can help us in the search for alien civilizations. And this is just the beginning, there is still a lot of work ahead, ”added the Chief System Administrator of the SETI Research Center for Alien Civilizations Matt Lebofsky.
