New Delhi: An increasing number of videos and stills showing unknown objects around the ISS have appeared on-line.
So many videos have appeared on Youtube in fact that the process of spotting unidentified extras in pictures and footage of the International Space Station seems to have become a pastime in itself.
The trouble is, most of these turn out to be nothing more than pieces of space debris, meteors, light reflections and other innocuous things. It is all too easy to see things flying past or floating around in footage taken from orbit.
