Now in a renewed bid to avoid such a scenario, experts have issued updated guidelines concerning the disclosure of an alien signal discovery to the general public.

Most notably, the changes reflect the need to properly confirm a discovery before announcing it so that rumours do not take hold on social media over something that may turn out to be nothing.

Communication should also be prompt, accurate and, perhaps most importantly, honest.Other things to take into account include the safety and privacy of the scientists themselves and the storing of sensitive data pertaining to a potential detection event.

"I think we hope to avoid researchers 'crying alien' prematurely, and yet to let the public know we want to be as transparent and open as we can be," said Prof Michael Garrett, director of the Jodrell Bank Center for Astrophysics and a prominent figure in the search for alien life.

"I don't know if it's this year, next year, or the next decade, or the next century, or whatever."

"But eventually, someone's going to find something... and so these guidelines are really for that person or that group of scientists that suddenly find themselves confronted with this huge discovery and wondering: well, what does this mean and what are the implications?"
