Scientists Receive Alien Signal From Distant Galaxy
Scientists have confirmed that they have received an alien signal, lasting 10 seconds, from a galaxy 2.5 billion light-years away. Pulses of radio as powerful as 10,000 suns were picked up by astronomers who traced the signals to a dwarf galaxy known as FRB 121102. FRB (Fast Radio Burst) are short-lived, high energy bursts of radio waves lasting just under 1 millisecond. Washingtonpost.com reports: “This really is the first ironclad association of a fast radio burst with another astronomical source, so it’s a pretty huge result,” said Duncan Lorimer, an astronomer at West Virginia University who reported the first detection of a fast radio burst (FRB) in 2007. FRBs are extremely brief pulses of radio waves, flaring with the power of about 500 million suns. Scientists have recorded just 18 of these signals, but studies suggest there could be as many as 10,000 a day. Their unpredictability makes them difficult to spot, and they appear to come from all over the sky. Understanding these bursts may open up a new field in astronomy, added Lorimer, who was not involved in the new reports. Because they travel so far to reach Earth, FRBs could be a tool for studying the mostly empty space between galaxies and mapping the distribution of matter across the universe. [...]
