Astronomers detect record number of repeating radio bursts from outer space, sparking alien theories.

Canadian astronomers have detected thousands of deep space radio signals, including 50 from repeating sources, using the high-powered CHIME telescope in British Columbia. The signals, known as fast radio bursts (FRBs), are considered one of the biggest mysteries in astronomy and are confirmed to have come from outside the Milky Way galaxy. Recent research has discovered that some of the FRBs were not random signal emissions and may be connected to one another. The CHIME telescope has an edge over other telescopes in discovering FRBs and has led to an increased rate of interception from a few tens to thousands in recent years.
