The anomalous object was spotted in front of the Sun in an image taken by NASA’s STEREO satellites.
The Internet was abuzz last week with claims of extraterrestrial visitors after the image, which was taken by the space agency’s pair of Solar Terrestrial Relations Observatory satellites, appeared on social media courtesy of Facebook user Pamela Johnson.
According to her postings, the anomalous sphere turned up on the feed on November 15th. She also claimed that several frames had been erased from the feed over the following few days.
While some Internet users have hailed the discovery as evidence of something exceptional, others were keen to point out that the ‘UFO’ was likely nothing more than a graphical glitch.
NASA even has a page on its website explaining how STEREO can produce images of this nature. – See more at: http://www.unexplained-mysteries.com/news/300941/blue-sphere-ufo-shows-up-on-nasa-camera#sthash.5nFuU95o.dpuf
