N.A.. may have tried to "call home" but new evidence indicates that he can now try to reach us.
Unusual and "mysterious radio outbreaks" have been discovered 3 billion light years away from the earth thanks to an artificial intelligence program on the search for extraterrestrial intelligence (SETI).
Researchers at SETI used a machine learning algorithm to reveal 72 new "Rapid Radio Blasts" (FRB) previously unidentified. The FRBs come from the galaxy FRB 121102. In combination with the 21 FRBs that were found on August 26, 2017, the total now comes to new 93 FRBs detected.
MASSIVE GLOWING & # 39; ROGUE & # 39; PLANET SPOTTED & # 39; OPERATION & # 39; IN SPACE  "Not all discoveries come from new observations," says Pete Worden, Executive Director of Breakthrough Initiatives, a SETI project, in a statement. "In this case, smart thinking was applied to an existing dataset. It has advanced our knowledge of one of the most tantalizing mysteries of astronomy. "
" This work is just the beginning of using these powerful methods to find radio transients, "says Gerry Zhang in the statement." We hope our success can inspire other serious efforts to apply machine learning to radio astronomy. "
It is still unclear what causes the FRBs, with SETI describing its source and mechanism as" mysterious. "The theories include" high magnetized neutron stars blasted by gas streams near a super massive black hole, because the suggestion of explosive properties is consistent with signatures of technology developed by an advanced civilization. "
What makes FRBs derived from FRB 121102 interesting is that these are once-only events. FRB 121102, however, has been unusually active as it was discovered in 2012, with researchers such as it calls a "repeater."
The researchers used the Breakthrough List scientific program to help review 400TB data and find the 21 outbreaks all seen within an hour, indicating that the source switches between periods of rest and frenetic activity. "
History of FRBs
It is unknown how common FRB really is.
FRBs, who are busy was born for the first time in 2007, is relatively new to astronomers and their origins are mysterious. According to ScienceAlert, some of them can generate as much energy as 500 million Suns in a few milliseconds.
Last month was a FRB that hit the earth almost 200 megahertz lower than any other radio bubble ever discovered.
We need to keep track of stories, SCIENTISTS TELL SENATORS
The discovery of FRB discovered in late July may have come from a number of events, such as black hole vaporization and eruptions of neutron stars, according to Nature.
However, astronomers, including those from Harvard, have previously said that they could not rule out the fact that FRB could be due to advanced civilizations deep in space.
If the truth really is there, it can only be 3 billion light years away from home.
