The Search for Extraterrestrial Civilizations (SETI) recently began using artificial intelligence to manage and analyze the huge amount of data it receives, with almost immediate results.
using a convolutional neural network system created by the University of California, Berkeley, SETI discovered 72 mysterious radio signals from a galaxy 3 billion light-years away in the direction of the constellation Ofstonic.
the signals came from the GreenBank Telescope in West Virginia, the world's largest all-convertible radio telescope with a diameter of 100 meters.
August 2017, the GreenBank telescope, listening to the rapid radio storm FRB 121102 discovered in 2012, suddenly received a bright radio burst again, lasting up to five hours and reaching 400tba.
Rapid Radio Storm (FRB) is a high-energy astrophysical phenomenon thought to come from outside the Milky Way and is a transient wave pulse that lasts only a few milliseconds, and its origin is not yet known, with some speculating that it could be a sign of extraterrestrial intelligence.
team led by Gerry Zhang, a Ph.D. student at the University of California, Berkeley, and member of the Breakthrough Listening project, developed a new, powerful machine learning algorithm that has created a convolutional neural network system that could theoretically clean up data sets more efficiently.
using the network's analysis of the vast frB 121102 data, they identified 72 missing FRBs, bringing the total number of detected rapid radio storms to about 300 since 2012.
FRB 121102 is the only stellar body known to transmit radio signals regularly, setI has been continuously observing and in-depth study, and without this new self-learning neural network system, scientists could miss a lot of important data by hand and traditional methods alone, having previously detected only 21 FRBs from the August 2017 data. Andrew Simon of the SetI Research Center in Berkeley,
, believes that the work of the Gerry Zhang team can give us a more detailed picture of the dynamic behavior of FRBs, and that if we are imaginative, the super-advanced civilizations may not be able to cram a bunch of interesting messages into such a short time to send them, or to use a pattern that we haven't yet figured out.
of course, whether frB is a distress signal from extraterrestrial civilization, the Breakthrough Listening Program will help us advance cutting-edge technology and better understand the universe around us.
