This is the intriguing moment a mysterious 'UFO' appears during a live TV news broadcast, sending sky-watchers into a frenzy of rumour-flinging excitement.

The saucer-shaped object flew across the skyline as Argentinian station Todo Notocias (TN) screened its noon newscast.

The three presenters appeared not to notice as the silver UFO flew over buildings in Buenos Aires as they read the day's headlines.

The Youtube footage appeared to be taken from a rooftop camera, with the incident prompting wild speculation on the internet.

The Mysterious Universe website excitedly reported: “How can newscasters who get paid to report the news not see the UFO flying behind them???”

"That’s what a lot of people are asking after viewing a YouTube video of a news program in Argentina that shows a large UFO flying across the sky behind the three seemingly oblivious newscasters. What happened?"

It added: "The disc-shaped UFO crosses the entire screen, at one point passing behind a multi-story building.

"It appears to be much larger than a drone and traveling too fast to be an odd-shaped blimp, airship or balloon.

"While the quality is good, it’s not clear enough for the magnification to help make a positive identification of the craft."

The website claims it was the second UFO sighting during a South American newscast in a less than a month after TV camera crew in Peru recorded a purple craft hovering in the sky.

But before other UFO-spotters could get too excited about the latest sighting, TN confessed it was a hoax - and the object had been added using digital trickery.

In fact, TN released an unedited version of the original news broadcast and there is no UFO or any other object in the sky outside the window backdrop behind the presenters.

While TN doesn't offer an explanation as to who was responsible for the hoax, it released this statement on its website saying: "The truth is that the video was edited and the UFO was added digitally.

"Here we show you the original video, without editing, with the full minute from 12:24, the moment in which someone wanted to fabricate a UFO on the air at Todo Noticias."
