Unusual objects are often seen in the imagery from NASA's Solar and Heliospheric Observatory satellites. But these are not actually present in space. They are artifacts of the stereo imaging process.
I have no doubt that many of these images are artifacts, but certainly not all. As with UFOs, crop formations,etc., some are hoaxes or known natural phenomena. There is always a percentage that simply cannot be explained. I'm glad we have videos like this one. We always need to keep our minds open and be aware of all sides!
