"A UFO expert claimed to have spotted a massive alien base capable of housing an entire fleet on Jupiter’s moon Europa. The expert came across the image of the alien base after going through a NASA photo.
The latest claim regarding the existence of a huge alien structure on one of Jupiter’s moons was made by Scott Waring of ET Data Base. According to Waring, he made the discovery while exploring the website WorldWideTelescope.org."

"An enormous alien structure was, they claim seen moving in the direction of Jupiter’s moon Europa which, according to some, resembles an ‘interstellar mothership’ or ‘an intergalactic cruiser’.
The image was taken by a Canon 650D camera with a 7D-300mm telescopic lens mounted on a tripod in someone’s backyard garden last week"

"Alien-hunters have spotted something so huge it may well be an alien mothership ‘observing Earth’ - or some form of even weirder alien structure, parked near Jupiter.
UFO fans SecureTeam10 are convinced that the blob seen near Jupiter is an alien structure - rather than, for instance, a blob on the camera lens."
