Scientists Detect Mysterious Radio Signals From Deep SpaceAn initiative set up to find signs of intelligent life in the universe has detected a series of mysterious radio signals from a dwarf galaxy 3 billion light years away. Scientists with Breakthrough Listen say they’ve found 15 fast radio bursts, or FRBs, from a deep space “repeater” called FRB 121102.
The numbers indicate when the first signal was discovered, on Nov. 2, 2012.
While a few other FRBs have been detected, what makes this one unique is that it was heard again in 2015, and its location pinpointed a year later.
Breakthrough Listen used instruments at the Green Bank Telescope in West Virginia to observe that location over 5 hours on Saturday, detecting 15 bursts over the entire 4 to 8 GHz frequency band, the organization said in a news release.
“It’s very funky how the individual bursts can pop up anywhere in this wide range of frequencies, even though each individual burst has a relatively narrow frequency coverage,” Peter Williams of Harvard University told New Scientist. “I have yet to see anyone offer up a good explanation for how that might happen.”
