Unexplainable Radio Signals <br />Detected From Outer Space The signals were discovered<br />by a radio telescope designed <br />for the Canadian Hydrogen <br />Intensity Mapping Experiment. Scientists say the signals <br />come from a galaxy approximately <br />500 million light years away. The "fast radio bursts" <br />repeated hourly over <br />the course of four days. This four day cycle would <br />repeat about every 16 days. According to Science X Network, <br />"the source could be a celestial body of <br />some kind orbiting around a star or another body." Scientists at the Massachusetts <br />Institute of Technology suggest the <br />signals are most likely not from alien lifeforms. Max Planck Institute, via 'USA Today' Scientists refer to the <br />"origin of short, dramatic bursts of radio light" as <br />"one of the greatest mysteries in astronomy right now."
