they have been finding UFO's in footage taken by the ISS.
This ones pretty cool and was only uploaded today. Im a big fan of UFOs' there just seems to be to much evidence pointing to the fact they do visit, and look over us.
This one is the one that made me subscribe lol
Sorry, can someone embed, i dont understand the "Insert video code"???

It's a speck of dust on top of ice particle...you can clearly see it. Other possibilities include space junk traveling at great speeds, or dust on the camera lens....if not lens flare.

The STS-80 footage of a group of bright dots forming a circle - now THAT is compelling imo. And the only compelling footage I've really seen so far. That someone official tried to explain it away makes it more pertinent to me.
35 Q: How much of it is “space junk”?
A: Very, very little, actually – if you use the standard definition of “space junk” to mean other satellites and pieces off of them, which constitute an impact hazard to human space missions and automated satellites as well. Because all orbiting objects are moving at tremendous speeds in different directions, when they do pass closely to each other, they zip past at several miles per second. Thus they are extremely difficult to detect visually. Anything that was seen over a period of time longer than a few seconds would have to have been something closely following the observer, and thus associated with the vehicle from which the observation was being made. Now, that's unless it was somebody else’s vehicle deliberately keeping pace, of course. But "space junk" as we commonly use the term? Hardly ever, maybe never.
36 Q: How often do astronauts see passing satellites out the window, or on TV screens.
A: Astronauts have observed other distant satellites, but not often. On special research programs, some astronauts have been able to spot ‘Iridium flares’ [Don Pettit, for example]. But on occasion when the crew was advised to look for a particularly close [a few miles] pass of a large satellites, every effort to detect the fly-by visually has failed. I have never found a single case of an observed nearby object turning out to be a passing satellite in independent orbit.
37 Q: But aren’t they flying through clouds of ‘space junk’? How could all those tens of thousands of objects be invisible?
A: I’ve got to admit that this has been really surprising to me since like so many others I had at first overlooked how big space is and how FAST criss-crossing orbits diverge. The earthside analogy of airplanes on different headings being visible to each other in midair as they crossed paths just overwhelmed a rational consideration of the way space is so very different, so unearthly. It makes sense now that eyeballs would almost never notice such fast passersby, so I can understand how the public has fallen for the same false analogy.
38 Q: Don’t astronauts keep a visual or radar watch out for approaching satellites in order to dodge a possible collision?
A: Surprisingly, no. At the relative speeds of objects in space, objects would only be detectable [if at all] within a few seconds of impact. Collision predictions are made hours or days in advance because much more powerful ground radars observe and catalog everything in orbit, and powerful computers predict their future flight paths to see if they may soon get close enough to threaten collision. The shuttle’s Ku-band dish antenna was mainly used for communications via relay satellites, but it could operate in a ‘skin-track’ mode for taking navigation ‘marks’ on a target satellite for a rendezvous or separation – but only at a range inside about 10 miles. And when using the antenna for tracking, it could not be used for data or video relay. There is no radar tracking capability on the ISS.
