Image Credit: Federal Government of the United States Authored by Dr Beatriz Villarroel and Dr Stephen Bruehl, the groundbreaking study has found compelling evidence to suggest that there is a distinct correlation between nuclear tests carried out in the 1940s and 1950s and the appearance of anomalous bright spots (or 'transients') appearing in photographs of the sky during that time.

Incredibly, unlike most UFO research, this study has actually been peer-reviewed, indicating that there is some genuine merit to the authors' methodology and conclusions.

"These are objects before Sputnik One when humans had nothing up there, and these things, no matter what they are, they need to be really flat, reflective like a mirror, and I personally don't know anything natural that looks like that," said Dr Villarroel.

The images themselves were captured during the Cold War by the Palomar Observatory Sky Survey in California .

The study focused on 124 nuclear bomb tests conducted by the US, the Soviet Union and the UK and found that the mysterious lights appeared briefly and then vanished at around the same time.That said, the research doesn't prove that the objects were extraterrestrial visitors - there may be some other explanation for their appearance in relation to the nuclear tests.

"Nature can always surprise us with something we could never have imagined," Dr Villarroel told NewsNation.

"So, I cannot exclude that there might be some other explanation that is just outside my imagination."

"But from what I see, I cannot find any other consistent explanation than that we are looking at something artificial."
