London: In a NASA footage, which shows two International Space Station (ISS) astronauts on a spacewalk, a more mysterious object has appeared in the background.
The five-minute clip, which was posted to YouTube, features a mystery craft hovering or flying in the pitch black background, the Mirror reported.
However, NASA, which has yet to comment on the puzzling object, confirmed that the spacewalk, which took place on October 7, saw the two astronauts completing tasks for the Expedition 41 crew.
