The object has disc-like shape and seems to emit unusual colourful lights in the picture. In a blog written by Scott C Waring of UFO Sightings Daily he said that there is a shining aura around the UFO that can be noticed if the screen resolution of the computer is high. Waring believes that this means the craft is really there. He said that NASA astronauts took some pictures and one accidentally posted to the NASA public site.
The image was also uploaded to YouTube by username Streetcap1 and this sparked debate among viewers with some thinking that this could be a sign of extra-terrestrial life while others attributed the image to faulty camera lenses.
On May 2, 2013, a strange object with orange colour was reported by a witness from San Lorenzo, California. According to the witness, the mysterious object appeared after a loud sound. The witness said that the UFO hovered in the sky without movement for around 30 seconds and it emitted yellow, orange and red lights.
In April, two schoolgirls witnessed a saucer object in grey colour flying across the skies of Khakassia in Russia. The two witnesses managed to take photos of the UFO, which amazed and stunned the viewers.
