A bizarre video has been released by conspiracy theorists which they believe shows "obvious" alien movement in a crater on the moon.
The strange footage, which was captured through a telescope, appears to show a moving object emerging from the crater momentarily before suddenly disappearing again.
The video, uploaded by US-based UFO investigators Secure Team 10, has now had more than 19,000 views on Facebook since yesterday.
Tyler, from Secure Team, said: "The amazing footage that you just saw showing some obvious movement and activity happening in a crater, caught by an amateur astronomer, could very well go down in the history books that there is current activity [on the moon]."
