A bizarre UFO has been spotted above Mount Everest.
The disc-shaped object can be seen in the sky over the Himalayas.
UFO watchers say the spooky object causes a silhouette and its height means it can't be a drone or helicopter.
The image is one of 477 stitched together by mountaineer and filmmaker David Breashears as part of an amazing two-billion-pixel photo.
The mosaic image is intended to show Mount Everest in all its glory and stretches from the camp of 500 prospective climbers at the base to the sky above.
