From the X-Files Dept: NASA Refutes Triangular “UFO” Seen in Footage Captured by the STEREO-B Spacecraft

UFO conspiracy theorists have attempted to use publicly available NASA images to prove that the space agency must be engaging in an elaborate cover-up, calling attention to new footage captured by a telescope onboard NASA's STEREO-B spacecraft — one of a pair of probes parked on either side of the sun which, together, provide a 360-degree view of the inner solar system. The footage shows Venus, Earth and, on the opposite side of the field-of-view, a strange triangular or diamond-shape "object" entering the field-of-view of the HI2 telescope on STEREO B around December 26, 2011. 


You can see the feature in question in this image moving from right-to-left, just above the trapezoidal occulter on the right side of the image. What is this, NASA asks? The answer lies on the exact opposite side of the image.

At the same time as this strange-looking feature starts being visible, the very bright planet Venus enters the HI2-B field-of-view from the lower left. Notice that Venus and the feature stay in step almost exactly opposite each other across the middle of the detector. This is not a coincidence.

The strange looking geometrical "object" is actually an internal reflection of the planet Venus within the telescope optics. This effect has been seen many times before. Here's a particularly striking example of internal reflections caused by the planet Earth as seen early in the STEREO mission, taken from NASA Stereo image artifacts pages.
