Mysterious objects filmed near International Space Station send UFO watchers into frenzy

A NASA live camera stream on the International Space Station captured a mysterious sighting, when a bright white orb was spotted racing past the camera in the distance.

For the third time in the last week, mysterious objects spotted near the International Space Station have put extraterrestrial enthusiasts in a frenzy.

Cameras onboard the ISS captured a white orb that appears to be moving in the distance. The UFO could be seen for more than forty minutes during the live video - but "strangely, there was no audio chat" during the stream.

The first sighting of several white orbs was seen on Aug. 4 by eagle-eyed UFO watchers hooked on monitoring NASA's live webcam, as first reported by the Houston Chronicle.

The second video, posted by Waring after its collection by a so-called "ufologist" with website Streetcap1, shows a white light glowing while above the earth's domed atmosphere on Aug. 7. It gradually disappears.

The latest video posted on Tuesday by Streetcap1 shows a cluster of white dots that appear over the edge of the space station.

After about one minute the dots — approximately four in number — fade completely away.
