A UFO was caught on camera above the Muiderslot Castle in the Neatherlands, a historical landmark, the Huffington Post reported.

Corinne Federer, 43, was visiting the castle High Dynamic Range (HDR) photos of the castle, that was built in 1285 a.d. near Amsterdam.

"In order to create HDR images, you take three or more exposures -- this one happened to be five -- and you shoot them all at the same time, because you then overlap the images and it gives you the full spectrum of light, which your camera can't capture but your eyes can," Federer said.

Afterwards, Federer looked over the photos she'd taken and saw something very strange.

"It was a tubular-shaped object that had an S-shaped fin on it. If it had been any type of missile, it would've had multiple fins, but facing the same direction. We heard nothing, it was completely quiet out," she said. "The more I flipped through the frames, it was kind of creepy," Federer recalled. "I've been shooting for quite some time and I've seen other stuff in the news, but I've never seen anything [like this] with my own eye," she said.

Federer said she couldn't wait to get home so that she could examine the photographs.

"I looked at the image information -- at the shutter speed -- and [the object] was blurred at 1/250th of a second, so it had to be going superfast," she said. "The object is not in the frame before or after, so it had to be going really, really fast. I was kind of blown away."

When Federer made some adjustments she realized that in a section of the next picture, the object was on the opposite side of the frame.

"The most interesting part of that, for me, is those fins are on the opposite side," she said. "At first, I thought the fin side must be a tail, but after looking at it from the second image, it almost looked like the fins were [in] the front and it was turning around and coming back into the frame."

Ben Hansen, a former FBI agent and the host of "Fact or Fakes: Paranormal Files" on the Syfy Channel, thinks that the photographs are genuine.

"Having reviewed the raw files, there's no overt indication that the photos have been manipulated with post editing software," he said.

Hansen doesn't agree that the UFO turned around and came back into the shot.

"If we were to assume that the protrusions are stabilizing airfoils -- such as might be found on a rocket or jet -- then it would make sense that the larger fins would be placed on the rear of the object and, consequently, we would know its direction," Hansen said. "However, the available pixels which blur and separate the protrusions from the main body equally suggest maybe they are NOT airfoils, but some other part of the object that is in rapid motion."

Hansen also doesn't agree that the UFO is in fact an extraterrestrial object.

"If I had to place my money on it, I would say that we're looking at insects," he said. "We typically see many wing protrusions on insect rod cases, but they do come in the single pair variety, too. It all depends on the shutter speeds and motion of the insects."

Hansen did point out another, less prominent, mysterious object in the photograph. On the right of the sun there appears to be a disk-shaped object.

There have been an few UFO sightings over the past few months. There was one photographed over a historic barn in the U.S and one spotted flying into a volcano in Mexico.
