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.
