NASA's New Horizons mission has discovered a strange indentation on the surface of Pluto that some are likening to a "bite mark."
Images released by the space agency show the feature located on the dwarf planet's western hemisphere in intricate detail.
It's believed the mark was likely caused by the process of sublimation, which occurs when a solid turns directly into a gas.

NASA notes, "The methane ice-rich surface on Pluto may be sublimating away into the atmosphere, exposing a layer of water-ice underneath."
The image was gathered by New Horizons on July 14, 2015.
