The image shows the infamous astronaut moments after he stepped onto the moon for the first time. The photo was uncovered by amateur photographer Andy Saunders from Culcheth in Cheshire after he used photo-enhancing technology, according to The Daily Telegraph. Mr Saunders spotted the opportunity to enhance the photo after noticing that Mr Armstrong had paused long enough for NASA to capture his face in high definition footage.
The technology used by Mr Saunders is popular with astronomers, allowing him to reveal the clear image of Mr Armstrong.
The discovery of the photo coincides with the 50th anniversary of the Apollo 11 mission.
It is one of the few photos of Armstrong on the moon, with most images showing Buzz Aldrin.
Mr Armstrong took most of the photos but some people believe Mr Aldrin decided not to take photos of Mr Armstrong because he was unhappy at being the second person to walk on the moon’s surface.

Mr Saunders told The Daily Telegraph: “I felt almost like an archaeologist brushing off the dust from some long-forgotten artefact.
“It was fortunate that he leaned forward to see what he was doing, and I noticed he had his visor up, which meant, crucially, his face was visible for a few seconds.
“I managed to get three separate good shots. I couldn’t believe it when the image emerged. You never see Armstrong’s face on the Moon, and there he was.’
Deputy Executive Director of the Royal Astronomical Society Dr Robert Massey said: “It’s an important record of a really crucial moment.”
US President Donald Trump took part in the Apollo 11 anniversary by hosting the two living astronauts who helped carry out the mission in 1969.
Mr Aldrin and command module pilot Michael Collins both attended an Oval Office photo-op that the White House opened to the press on Friday.
During the event Trump said: “What a career you’ve had. Great careers.”
Mr Armstrong died in 2012 but was represented by his two sons Eric and Marc.
