A UFO enthusiast pointed out a structure on Art Alien TV that could be a building mounted on Rosetta Comet 67P.

Joe White, of Art Alien TV, said the monastery-like building mounted on top of the comet appeared to have an apex roof, chimney and windows, reported International Business Times. He estimates that the structure is 100 meters long (328 feet). The estimated building size is compared to the estimated size of the Rosetta comet - 4,100 meters (13,451 feet).

Once White was convinced he discovered a structure on the comet he showed a picture to his wife, who also said it resembled a monastery, reports IBT. The couple since dubbed the building "Whites Monastery."

White claims that no photo enhancement was done on the image besides contrast and negative processing, which, according to White, could be achieved with the help of a basic software.

To see the structure, White told IBT to download the photo, rotate at 45 percent and then zoom in.

White has since published an Art Alien TV episode on YouTube showcasing his discovery. The video became an instant hit.
