In a presentation delivered to a meeting held by the Search for Extraterrestrial Intelligence Institute last spring, a scientist from NASA put forward the notion that the idea that extraterrestrials may already be visiting Earth isn’t such a crazy one, and that SETI might invest some resources into studying high-quality UFO reports for signs of non-human intelligences — signs that might indicate that the subject of their search might be closer to home than they think.

The Search for Extraterrestrial Intelligence program is currently investigating a high-energy signal burst that originated from a star 95 light years away, in the constellation Hercules. SETI senior astronomer Seth Shostak cautions that this is unlikely to be an artificial signal, as there are a number of natural phenomena that could also have produced the signal.

The signal was recorded by Russian astronomers at the RATAN-600 radio telescope in Zelenchukskaya. Unfortunately, the signal was recorded on May 15, 2015, nearly a year and a half ago, a delay that severely hampers verification of the other signal from other telescopes. Nonetheless, SETI will be listening to the star on the off chance that there might be a repeat of the signal.

Mysterious signals from outer space are being detected by scientists, and so far their origins are unexplained.

The Fast Radio Bursts (FRBs) have been foxing astronomers since they were initially identified in 2007; the first one, named the Lorimer burst after its discoverer Duncan Lorimer, was a random signal lasting just five milliseconds. This original FRB was so fleeting that it left researchers wondering for years whether it had merely been a malfunction in one of the telescope’s instruments, but since then several other isolated signals have been detected.
