Alien conspiracy theorists went nuts (as you can see above) when they saw a strange, massive, triangle shaped “object” captured in a video by NASA’s STEREO-B spacecraft, which with its twin is parked either side of the sun. This time, NASA’s been ticked off enough, probably by the constant barrage of phone calls and cover-up articles, to debunk it publically.
In a post on the STEREO project’s site, the boffins explain it’s all to do with Venus and its bright shining light. The artefact is created by an internal reflection of Venus, bouncing around the mirrors and lenses inside the telescope mounted onto STEREO-B:
“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.”
They've even knocked together a handy diagram to show you exactly what they mean:
So there you have it – blame Venus and total internal reflection for the video; not some highly intelligent and technologically advanced alien race with a colossal spaceship. They’re not headed to Earth, and they’re not going to steal our brains. For now. [NASA via Space]
