However, after many conspiracy theories insisted that the sphere was a UFO, NASA pulled down the image after they say that the picture was a corrupted image.
"On rare occasions, the SECCHI image processor on board STEREO becomes overloaded, and produces corrupted images," NASA explains. "Because the pictures from the Heliospheric Imager (HI) telescopes are built up from a large number of exposures added together, this sometimes results in 'double exposures,' where data from several telescopes appear in the same image."
But conspiracy theorists are not buying any explanations from NASA. They say that the image of the round object is too distinct to be simply a crossover over of sun images. They also insist that the object appeared a lot smaller than the sun image, proving that it is not the same object.
"Whether the object is one of the giant extraterrestrial or interdimensional spacecraft, which are accessing our solar system, using the Sun as a Stargate or an unknown celestial body like the famed planet Nibiru. It is evident what happened on the 17th was not the result of an equipment failure," UFO Sightings Hotspot speculated fancifully.
UFO believers say that NASA realized their mistake after posting the image and quickly settled on technical problems to have caused the blue beam.
