Mystery ‘craft’ appears to watch astronauts on International Space Station

This intriguing footage captured by NASA shows a ‘UFO’ hovering near the International Space Station as two astronauts conduct a spacewalk.

In the five-minute clip, posted to YouTube, NASA astronaut Reid Wiseman and Alexander Gerst, from the European Space Agency, are seen on the spacewalk.

The pair, clad in spacesuits, step outside the carry out a series of repairs.

However, for around five seconds, a mystery craft – which is presumably hovering or flying in – is also visible in the background, in the pitch black.

It appears in the camera frame between the space station and Earth – an area filled with just blackness only a few seconds earlier.

Unsurprisingly, NASA has yet to comment on the puzzling object. TRUNews
