Mysterious Signals from Faraway Galaxy
Mysterious radio signals have reached Earth from a galaxy far, far away. The strange beams, known as fast radio bursts (FRBs), last no more than a millisecond, but scientists say each pulse carries as much energy as our sun emits in a century.
The signals are coming from the edge of a dwarf galaxy 3 billion light-years from Earth, and it has been suggested the flashes are messages from alien civilizations with technology far superior to ours.
A second theory is that the bursts are the result of a collision and subsequent explosion of incredibly dense matter, such as a black hole or neutron star. Yet another theory is that the FRBs are created when distant stars collapse.
An international team carried out a monitoring campaign using the Parkes Telescope in Australia and the Green Bank Telescope (pictured above) in the United States, and the combined analyses were based on observational efforts across three continents.
