NASA opens up about 'UFO' in STEREO images

Eyebrows were raised recently when a strange wheel-like object showed up in solar observatory imagery.
The images were captured by NASA's STEREO mission (Solar Terrestrial Relations Observatory) which originally consisted of two spacecraft which launched back in 2006.

Although only one of these is still operational, the mission continues to capture some spectacular shots, including one recent set of images which featured a rather unusual looking anomaly.

Resembling a wheel with four spokes, the strange object was captured by the HI2 telescope on STEREO Ahead (its twin was called STEREO Behind) back in February.

While some eagle-eyed social media users were quick to imply that the anomalous circular object was a UFO, NASA has since explained on its website that it is actually a reflection of the planet Venus.
"At the same time as this strange-looking feature starts being visible, the very bright planet Venus enters the HI2-A field-of-view from the left," it wrote.

"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."

A video showing the progression of the anomaly can be viewed - here.

So NASA satellites produce images with internal reflection thereby mucking up the image with artefacts?  What a waste of taxpayers money.

It's the pros and cons of sensitivity vs the occasional reflection due to a very bright object.

...and release a far more contagious and deadly virus. Sit back and wait for us all to die so they don't have to make a mess.

Did you read the links, at all?

Perhaps if you learnt a little about photography, you might learn the VERY basic fact that all camera/lens combinations (yes ALL) will have lens flare effects, especially when imaging small bright objects on dark backgrounds. No matter how well designed is the lens system, there is simply no way to avoid internal reflections when you have lens elements. This is REALLY basic stuff.  Plus, if you had watched even a small number of Stereo images/animations, you would have seen this effect before. So, to summarise your 'contribution', you don't understand lenses, and have never taken any interest ... [More]
