The sensational claim was made by Dr Norman Bergrun, a well respected engineer who held a position at Nasa’s Ames Research Centre.
Dr Bergrun said that “living alien UFO spaceships” are using the rings of Saturn as a hiding spot and that they are “proliferating” at am alarming rate.
The former Nasa employee has previously said that the amount of spaceships has reached “critical” levels, and that authorities should keep an eye on it.
He added that the rings have become so compact with UFOs that they are now starting to gather around the likes of Jupiter and Neptune.
Dr Bergrun: “What I found out is, these things inhabit Saturn, that’s where I first discovered them, and they’re proliferating. You can find them around Uranus and Jupiter.
“Wherever you see some rings, that’s where I see the aircrafts, I call them a ring maker.
“I say that it is electromagnetic because I can identify streamline patterns with respect to it that I knew were what we called ‘potential lines’ and that says it was electrical.”
Prominent UFO hunter Scott C Waring believes that Dr Bergrun has blown the lid on Nasa’s biggest secret.
He wrote on his alien-dedicated blog UFO Sightings Daily: “Norman Bergrun worked in a top secret area inside the US government and has personally witnessed seeing photos directly from Nasa that had UFO near Saturn that make the rings around Saturn.
“He says he has personally seen an increase of alien ship activity among the rings of Saturn over his career. Something has to be done.”
