A viral video making the rounds on the Internet supposedly shows a humanoid figure walking along the surface of the moon.
The YouTube video, from user Wowforreel, has been seen more than 2 million times in less than a month. According to Australia's 9News, the owner of the YouTube channel said he started investigating the shadow after receiving an online tip from another web user.
The images used to create the lunar images for Google's moon series come from NASA.
There's no word from NASA as to exactly what they believe the image to show. Of course, there has been plenty of speculation from many corners of the web as to what or who -- they think the shadowy figure is.
