Mexico City.- During the year 2007 a group of Australian astronomers detected the first of a strange series of phenomena, this event they called "Rapid radio bursts" (in English, "Fast Radio Burst" or FRB). These are a series of very high-energy radio pulses that barely last a few milliseconds and that seem to come from outside the Milky Way. Although during this time it had not been possible to clarify the origin, there were only speculations that they had been created by extraterrestrial life.
The year passed, the researchers finally located the origin of one of these bursts, called FRB 121102, in the active nucleus of a small galaxy located 3 billion light years from Earth.
One of its peculiarities, as it was ascertained then, is that this signal is repeated every so often. Now, the researchers of the 'Breaktrough Listen', a project of intelligent life search (SET) of the University of California in Berkeley of the United States, has discovered a total of 72 rapid bursts of radio in this source using techniques of artificial intelligence.
So far, it is known that rapid radio bursts (FRBs) only last for a few milliseconds and come from distant galaxies. It is unknown what its origin may be.
Among the most accepted possible theories is that they come from highly magnetized neutron stars and are bombarded by gas currents from supermassive black holes. Other theories maintain that its origin could be in advanced extraterrestrial civilizations.
On this occasion, the algorithms began to analyze the data collected by a large radio telescope, the Green Bank, located in West Virginia, for five full hours, on August 26, 2017. In a previous work, there were captured 21 bursts in a period of one hour.
