The Russian Space Probe Soyuz IV - currently on a mission to explore the surface of Jupiter - has instead discovered a pair of Underpants orbiting the giant planet!
Scientists at the Star City Mission Control Centre near Moscow have already begun analysing the first amazing pictures beamed down from the spacecraft, and believe the underpants to be British or Irish in origin, as an ultra-violet scan has revealed a Marks & Spencer St.Michael label at the rear.
Analysts also believe there are tell tale signs on the inside rear of the rogue underbags of recent usage as a large brown streak is clearly visible.
A spokesman for The European Space Agency who are controlling the Soyuz IV mission Hans Von Lederhosen said "We believe zat ze underpantz are of ze soiled variety und zat zey haf been discarded in error by a careless Astronaut vile he vas goink for a poo."
The intergalactic undies, currently racing across the universe at up to speeds of 250,000 mph are not thought to present an imminent danger to other spacecraft unless they got stuck to the windscreen of a manned mission.
The incredible speed of the underpants - which is believed to be a world record for underwear - is a tribute to the quality construction of Marks & Spencer said a company spokesman.
