AN ASTONISHING video showing two dark oblong objects blasting above Earth's atmosphere has been hailed "the best UFO footage out there”.
In the YouTube clip, the camera follows the objects as they shoot along together, before zooming in on to one of them for a close up view.
Jeffrey Boyd Jr, who posted the video, entitled the startling clip "NASA sat two UFOs! Close ups, Wtf is this?"
In a blurb for the video he said: "NASA sat feed catches two objects, UFOs? "Cruising from North Pole! Closeup! Great resolution, very clear. Has windows? What is this?"
Some YouTube viewers were stunned.
One posted yesterday: "If this is legit, it's the best footage out there so far. Impressive."
Another said: "Wow, just wow."
Beyond The Strange YouTube channel was also in awe.
A message posted on the site read: "If you have any doubts about UFO's watch this NASA footage of two Unidentified Flying Objects on the screen, in Hi-Def!
"This is not a joke or a hoax.
"Check out this footage before it's taken down!"
One poster was so amazed, he said it had to be fake.
He said: "I can tell you right now that's fake... anyone can tell."
However, before people start thinking it is proof of the infamous "cube UFO over Texas," the truth of the matter can be revealed.
Many suspected UFO sightings have legitimate explanations such as blurred birds, balloons, out of focus planets, lens flares, or as in this case satellites.
He recognised the objects as two satellites from the NASA GRACE mission (Gravity Recovery and Climate Experiment), which were sent into orbitto monitor climate change.
He also found the original NASA video that the clip was recorded from confirming what they were.
With the hashtags hoax and fake news, Mr Brando tweeted: "This video shared on #YouTube is easily explained: those objects are twins satellites from #NASA GRACE mission (Gravity Recovery and Climate Experiment)."
