Hi, Mr. (name excluded) and Mr. (name excluded) -
It's interesting that folks have the time to stare at our movies and find interesting features, but no luck Googling, say, "STEREO image artifacts." If you had, you would have found, among other things:
stereo.gsfc.nasa.gov...
(see the HI-2 case, about halfway down the page), and then perhaps found our Planet Finder:
stereo.gsfc.nasa.gov... ,
which indicates that currently, Venus is probably the brightest object in the HI-2B field of view, and thus likely to be the source of the internal reflections.
The HI's are not what most people think of when they think of telescopes; instead (see:
www.sstd.rl.ac.uk... ,
Figure 5) they're two single-lens cameras recessed below the side of the spacecraft and placed at the end of a series of baffles to remove stray light from the Sun, which is (Carl Sagan imitation time) billions of time brighter than the signal we're looking for. I can't honestly say I know which of the many structures inside the HI instrument produces the triangular or diamond-shaped internal reflections (though looking at that Figure, I'm guessing it's the HI-1 camera), only that they've been seen before.
Wishing you both a happy new year,
Joe Gurman
P.S. I wouldn't call that an "official explanation," as I'm not an official anything, just a scientist.

Why do the background images go over the object when it's moving? It's like the object is behind the background.

ok i dont know where you are going with that lecture but i agree we are not the only intelligent life in the universe however yes you need to keep an open mind but when you do common sense and education must prevail no matter what you want to believe, listen to your head not your heart.
i think this thread can be closed but because some people are listening to there heart they are frantically trying to prove there's something in the images even though the odds are stacked against them its time to admit defeat there no shame in that and look forward to the next weird and wonderful object to show up like this.

Thanks for posting the reply you got from NASA.
It confirms what some of us had come to believe anyway, but nice to hear it from a NASA scientist.
Why this thread is at 95 flags and growing is beyond my comprehension.
Huge UFO Pyramid Incoming!
It is massive and heading our way

problem solved we know what it is now.
