Have you ever looked up at the sky and wondered if there were aliens looking down upon you? Have you ever turned your radio to a specific frequency and picked up mysterious signals that appeared to be coming from far away? This phenomenon has been observed by many scientists.
Scientists and researchers have frequently observed strange signals coming from the far-off cosmos.
Are these signals from aliens or is there a more logical and reasonable explanation? Let's find out.
Astronomers commonly detect what is known as fast radio bursts, or FRBs, as they search for signs of celestial objects. FRBs commonly last only a few thousandths of a second and usually have fairly irregular patterns.
The sources of FRBs are difficult to precisely track down and locate. Since they can come at irregular intervals and from virtually any part of the sky, they take some serious astronomical skill to track down and pinpoint.
Once astronomers do track down and isolate a given FRB, that's when the fun begins. What may at first appear to be seemingly random bursts of radio-signals, is often found to be regularly-occurring pulses.
