BERKELEY, CALIFORNIA — Astronomers last month reported detections of radio bursts from a far away galaxy.
Writing in the Astronomer's Telegram, scientists reported 15 fast radio bursts detected from a dwarf galaxy some 3 billion light years from our own. Scientists suggest the bursts may have come from a magnetar, which is a rotating neutron star with a strong magnetic field.
Researchers also speculate that the bursts may originate from alien laser technology used to propel and power spacecraft, like wind powers sails on a ship, according to a University of California, Berkeley news release. That theory is similar to Breakthrough Starshot, an initiative aimed at propelling nanocraft to Proxima Centauri with Earth-based lasers.
Whatever they came from, researchers say that those signals began travelling from their galaxy over 10 billion years ago, when ours wasn't even 2 billion years old.
