Strange signals coming from space every 16 days are puzzling scientists

An odd radio signal is coming from space, starting and stopping in regular 16-day cycles. A team of Canadian astronomers was the first to report finding the source, which they discovered using a novel radio telescope.

This newly-discovered burst of radio waves, called FRB 180814.J0422+73, does not fit any known cause, leading to range-ranging speculations on its nature, ranging from simple interactions between stars, to suggestions the waves are signals from intelligent lifeforms.
