Video: Don't miss an alien and its shadow walking on moon!
NASA is yet to confirm what this image is all about but for YouTube users, the image is not less than an alien and its shadow.
The image is part of a YouTube video now viral on the internet.
The video from a user named Wowforreel has been seen over two million times in less than a month.
The images used to create the lunar images for Google's moon series come from NASA.
The owner of the video started investigating the shadow after receiving an online tip from another web user, Australia's 9News reported.
