Astronaut Scott Kelly Tweets Photo With Strange UFO in Corner

Scott Kelly became a bit of a celebrity on social media for his tweets while aboard the International Space Station. One however, caught the eye of conspiracists and the general public alike. In the top corner of the photo, a structure or two separate objects emitting light or reflection can be seen. People were quick to point out it’s just a part of the space station, but others argued that the observation window does not have anything protruding in that area. So what was it? A UFO? A smudge? We may never know.
