What at first glance appears to be a blotch of blue pixels, could be an extraterrestrial object of epic proportions.

According to self-appointed UFO expert and conspiracy theorist Scott C Waring, the blue object is a planet-sized space station constructed by immortal alien beings.

Mr Waring, who runs the blog UFO Sightings Daily, said: "This three-dimensional object in space is 100 percent proof that aliens create structures that are as big as planets.

"Here we see a giant blue planet size space station.".

The object in question was found using Google Sky - a celestial map of the night sky that reveals the locations of stars, constellations, galaxies and planets.

He said: "I found it using Google Sky map, just copy paste the coordinates into it and you will find it?

Here we see a giant blue planet size space station.
