The unexplained signals from the other side of the universe known as fast radio bursts are a rarely observed phenomenon and only one of them has been picked up more than once. Now scientists engaged in the search for extraterrestrial intelligence say that lone repeating fast radio burst (FRB) is being heard twittering away. FRBs are bright, millisecond-long pulses of radio signals from beyond the Milky Way that were first identified only a decade ago. Suggested explanations include everything from neutron star outbursts to alien civilizations using some form of directed energy to propel a spacecraft. One burst first observed in 2012, named FRB 121102, was later found to repeat in 2015. On Saturday, UC Berkeley postdoctoral researcher Dr. Vishal Gajjar used the Breakthrough Listen backend instrument at the Green Bank Telescope in West Virginia to target FRB 121102 once again. After observing for five hours and across the entire 4 to 8 GHz frequency band, Gajjar and the Listen team
