London: A balloon having extra-terrestrial particles landed in West Yorkshire city, Wakefield.
The city, famed for producing the pink vegetable, was the landing site of the balloon, which brought back the extra-terrestrial particles after a trip to the edge of space, the Mirror reported.
Molecular biologist Prof Milton Wainwright, who led the project, said that the findings could be revolutionary.
He said that people may assume that the biological particles went up from Earth but a particle of that size could not have lifted to such heights.
The balloon, which was launched near Chester by the Sheffield University team, was carrying sensors that became exposed only after the balloon reached the height of about 14 - 17 miles above the Earth.
When the balloon touched in Wakefield, it picked up an algae fragment and `biological entities` which is of unusual size.
