A UFO expert claimed that some of the photos NASA took on Mars accidentally captured an oval-shaped alien structure. Based on the photos, the UFO expert noted that the structure had tinted windows.

Claims regarding the existence of alien buildings on the Red Planet were made by Scott Waring of ET Data Base. According to Waring, he came across photos containing the alleged alien structure as he was going through the raw images taken by NASA’s Spirit rover.

This rover was officially launched in 2003 with the sole mission of exploring the Martian surface. Its mission ended in 2011 around a year after NASA lost contact with it.

During its stint on Mars, which lasted for almost a decade, Spirit was able to collect valuable information regarding the Red Planet. These included stunning photos of the alien planet’s surface.

As Waring was going through these photos, he came across a couple of them that were taken by the rover on SOL 1172. The UFO expert pointed out that the photos captured an oval-shaped building on Mars.

Based on the photo, the structure appears to have been tilted on its side, which may have been caused by seismic movement on Mars. But aside from this, Waring noted that the structure features a dark window that stretched across its surface.

Although the object looks like a rock, the UFO expert said that it does not resemble the other stones and rock formations scattered in the area.

“While looking at the Mars Spirit Rover photo called Panoramic Camera, Sol 1172, I noticed what looked like an oval-shaped building,” Waring wrote on a blog post. “The thing that stood out the most was that it seems to have a dark tinted window all the way around the building.”

“The window seems to be once piece,” he continued. “Some people will say it’s a rock. Look carefully and you will notice there are no rocks anywhere that look similar to this, thus...it’s not a rock.”

Aside from the oval-shaped structure, Waring also spotted another alleged alien building in the photo. The other structure, which is situated near the upper left portion of the oval building, has a slightly triangular shape.
