NASA Says UFO Seen On Video Is Actually Trick Of Light

January 20, 2012

NASA scientists used the laws of physics on Thursday to publicly debunk conspiracy theorists that claim the space agency is engaging in an elaborate UFO cover-up scheme.

The controversy stems from a bizarre, triangle shaped objected seen on video captured December 27 -29 by NASA´s STEREO-B spacecraft — one of two probes parked on either side of the sun which, together, give a 360-degree view of the inner solar system.

The alien hunters say the footage shows Venus, Earth and, on the opposite side of the field-of-view, a mysterious object headed towards Earth.

“Comparing it for size to the planetary objects that are seen in this telescope, if my calculations are correct, that thing is enormous,” said YouTube user “BeePeeOilDisaster” in a video commentary on the STEREO-B footage, reports Life’s Little Mysteries.

Rumors of a potential cover-up came a few days after NASA scientists updated the STEREO website to display newer images.

This is not the first time alien conspiracy theorists have found what they believe to be UFOs in images captured by the STEREO probes.

However, this time, NASA scientists working with the probes´ data decided to address the charges directly.

In a post written on the STEREO website, the researchers said the peculiar, triangular-shaped feature seen in the footage was simply a trick of the light.

“The answer lies on the exact opposite side of the image,” the NASA scientists wrote.

“At the same time as this strange-looking feature starts being visible, the very bright planet Venus enters the [telescopic camera's] field-of-view from the lower left.”

The scientists emphasized that Venus and the triangle — seen opposite each other across the middle of the field of view — remain in step as they move.

“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,” the scientists wrote.

This optical effect, the scientists said, occurs as incoming light reflects back and forth off lenses and mirrors inside the telescope.

The shape of artifacts produced by this scattered light – typically triangles and circles – depends upon the relative orientations of those lenses and mirrors.

The scientists cited another example of internal reflection — light from planet Earth — that can be seen in a STEREO-B image (see image above) from May 2007.

Additional examples of internal reflection and other optical and data-processing artifacts are displayed on the scientists’ “Image Artifacts” Web page, along with descriptions and explanations of the assorted effects.
