It shows a long, brown oval known as a “brown barge” on the planet’s South Equatorial Belt.
But on closer inspection, there appears to be a small green object floating above the surface.
The bizarre finding was uploaded to YouTube channel thirdphaseofmoon, where presenters Blake and Brett Cousins speculated it was a spacecraft.
“It must be at least 100-miles wide and could be a craft”
“I’m actually blown away by it – it is so weird – it does not look right,” they revealed.
“Whatever that object is, it must be massive.
“It must be at least 100 miles wide and could be a craft.”
The clip was shared online today, where it has racked up more than 3,600 hits already.
And viewers were just as baffled.
“If that is a spaceship, it is absolutely massive,” one comment read.
Another added: “The reason why we now have a Space Force is because there is a threat from UFOs.”
And a third claimed: “There is loads of strange stuff going on.”
But there may be a logical answer.
The green colour could be caused by ionising radiation – something Jupiter is well known for emitting.
