According to the January 19, 2012 Fox News article NASA debunks mysterious triangular 'UFO', 'Once again, alien conspiracy theorists have attempted to use publicly available NASA images to prove that the space agency must be engaging in an elaborate UFO cover-up. And, once again, they've been foiled by the laws of physics.'

Digital film, taken around December 26, 2011, by the HI2 telescope from the NASA probe STEREO-B shows Venus, Earth, and a strange-looking triangular, or diamond-shaped, object on the opposite side of the field-of-view.

The twin NASA probes STEREO-A and STEREO-B are in orbit around the Sun, one of the probes on one side of the Sun and another on the other side of the Sun. And, one is ahead of Earth in its orbit about the Sun, and the other one is behind Earth.

The positioning of the probes provide a 360-degree, three-dimensional view of the inner solar system for its Solar Terrestrial Relations Observatory (STEREO) mission.

The triangular-looking object appears in several YouTube videos. One of them is 'AMAZING TRIANGLE UFO!!! Object seen on NASA's Stereo B HI2!!!'.

Upon seeing this triangular object, and seeing that conspiracy theorists were making a big deal about it (calling it a 'cover-up' by the U.S. space agency), NASA decided to confront the controversy head-on.
