Scottish scientists re-examined the rating scale of extraterrestrial space signals.
A team of international researchers, led by researchers from the University of St. Andrews and the SETI (Search for Extra-Terrestrial Intelligence) Institute Mountain View, California, redefines the Rio Scale – the alien recognition scale.
The Scale developed in 2001 is a tool used by astronomers searching for extraterrestrial intelligence (ETI) and giving a score between zero and ten. The public can quickly see how important a signal really is.
The revision aims to achieve consensus on academic disciplines when classifying signals that potentially indicate the existence of advanced extraterrestrial life.
The scale measures the consequences for humans when the signal is from aliens, as well as the likelihood that the signal really comes from aliens and is not a natural or man-made phenomenon.
The lead researcher Duncan Forgan from the University's Center for Exoplanets said: "It is absolutely crucial that when we talk about something as significant as the discovery of intelligent life beyond Earth, we do so clearly and cautiously."
Dr. Forgan added "Rio 2.0 allows us to quickly signal that the general public can easily understand it and help us to trust a world full of fake news."
The new Rio The Standing Commission of the International Academy for Astronautics via SETI has now been presented with a scale for official ratification.
Jill Tarter, co-founder of the SETI Institute, which is an important contractor to NASA and the National Science Foundation, said: "The whole world knows the Richter scale for quantifying the Severity of an earthquake; this number is reported immediately after a quake and then refined as more data is consolidated.
"The SETI community is attempting to create a scale that will accompany reports of any claims about the discovery of extraterrestrial intelligence and that it may be refined over time.
" This scale should include both the significance and the Convey credibility of the claimed evidence.
"Rio 2.0 is an attempt to update the scale to make it more useful and compatible with current forms of information dissemination, and to allow the public to become familiar with the scale."
The new Rio scale has now been submitted to SETI's Standing Committee of the International Academy of Astronautics for official ratification.
