A video posted to YouTube on June 21 - claiming to show three UFOs leaving the Earth’s atmosphere, and accusing NASA of deliberately cutting its feed from the Space Station - has been going viral.

The video, titled “UFO Mysteries: UFOs, Angels Or Biological Creatures Seen Leaving The Earth?” is said to be footage from the livestream of NASA’s International Space Station.

The footage of three lights, combined with the alleged suspicious timing of camera difficulties, has many declaring we now have “definitive proof” that aliens exist. Further, many claim it proves a government coverup of a mysterious alien species.

The truth, however, may be far less exciting.

In the YouTube video, a small speck of light can be seen rising from the atmosphere, followed by two more very small and faint lights, also rising away from the Earth.

The feed then cuts out, with the message: “Please stand by. The High Definition Earth Viewing experiment is either switching cameras, or we are experiencing a temporary loss of signal with the International Space Station.”

Now, these specks very well could be some alien visitors, just leaving dinner at Roswell, but there are also alternative explanations.

The light may have been satellites, space debris, a glitch, or even glimmers of sunlight. The ISS completes an orbit of Earth every 92.91 minutes and moves at 17,100 miles (27,600km) per hour, so it is not unlikely to run into any of these things.

While the ISS camera runs 24/7, it often cuts out or switches cameras, sometimes even temporarily shutting down the feed.

The new viral video surfaced approximately a week after UFO hunters claimed to find a pyramid on Mars, thus proving the planet was once inhabited. Scientists have scoffed at their claims, saying it is actually a rock that is roughly the size of a car.
