One video captured a fleet of UFOs leaving the moon. The video was stunning enough to make conspiracy theorists affirm that extra-terrestrials live on the moon.

First uploaded on YouTube by Geri Vigil, titled "Large Group of UFOs Leaving the Moon", the video graphically reveals a number of strange blobs that are shifting away from the bottom-left area of the moon. However, there seems to be some shimmering light in that place.

So was it evidence of an alien departure?

The diehard UFO believer and blogger Scott C Waring picked up the footage and was convinced that it showed alien UFOs. "It's been known by a lot of astronomers that if the edge of the moon is observed well enough, you will see fleets of UFOs in orbit move around the moon's horizon. These objects are clearly in orbit around the moon and may be there to protect the moon from humanity.

"We haven't been back to the moon since the Apollo missions, and there is no intention of going back. Many Apollo astronauts have stated that they saw UFOs on and near the moon, so maybe these objects are a form of protection from future Apollo missions landing on the moon. It may be owned by a species that's not so friendly about sharing."

The comments to the upload had the usual mix of believers, sceptics and sarcastic commentators. One viewer posted: "Those aliens were rooting for the establishment of the New World Order, but since Donald Trump won the elections, they lost hope and decided to just go home...  that's what we are seeing in this video."

Talia Adagio1 added: "I see the same effect in reverse on the right side, they look like they are landing instead."

Gary McKinnon, who became famous when he tried to hack into NASA and US military in order to probe UFOs, also put in his word. He wrote: "There's a lot of footage of objects leaving the moon, as more people get better telescopes it's being observed more often. This looks like far too many though, I think it must be visual artifacting."

John Biondo who also posted: "UFO's are NOT what you're seeing. It is a phenomenon seen anytime you look at the Moon's edge. I have lots of telescope time. You see this all the time, it's called Chromatic Aberration. (Google it)  You see it more when the lens is out of focus as well, such as in this video."

And another viewer posted: "This is just an optical illusion. It happens when the air's humidity is high and the light from the moon gets distorted or multiple light sources/bright objects in the distance on the earth gets reflected. It's some kind of mirage, but definitely not UFOs leaving the moon that's for sure. Amazing video anyway!"
