An unusual claim is based on the images taken from the Apollo 17 mission in 1972.
In it, the astronauts Eugene Cernan and Harrison Schmitt explore the surface of the moon and eventually turn to the camera.
The sun's reflection is visible in both helmets – but one of the "researchers" claims that everything is not the way it seems.
She says: "Here's a clip from the NASA-supplied clipboard. Without adjusting anything, you can clearly see that the Sun is at the center of attention.
"It's not really the Sun, it's the center of attention in the movie studio.
"You can see that light is supported in a metal housing around the headlight.
"These two do not walk on the moon, if you have a fascinating eye, you can see that there is a person standing there.
"You see his legs and a dark jacket, almost as if standing with his hands in his pockets."
"This is not the true Sun, this is the focus of attention in the film studio"
The conspiracy theorist
The next week will mark the 50th anniversary of the Apollo 11 1969 mission.
A number of conspiracy theories that have since persisted in NASA have also emerged around him.
Some claimed that the astronauts involved were "pushed" to hide secret information about NASA programs – even though they had no evidence.
One of the extraordinary events that often occurs is the death of astronauts Virgil Grissom, Ed White and Roger Chaffee in 1967.
During the simulation, they were killed in a devastating fire on the Apollo launch pad.
The interior of the command module was fired and each of them was suffocated – there was never been a source of fire.
However, there was no sign of unfair play.
