The two orange eyes and white button nose are actually very bright galaxies and the smile arc is created by an effect known as gravitational lensing, according to a statement on NASA's website.

Galaxy clusters, the most massive structures in the universe, exert such a powerful gravitational pull that they warp space-time and the light coming from behind them, which created the arc of light that forms the smile, NASA said.

The galaxy cluster SDSS J1038+4849 in the photo was studied by Hubble's Wide Field and Planetary Camera 2 (WFPC2) and Wide Field Camera 3 (WFC3), according to NASA.

A version of the image was entered into the Hubble's Hidden Treasures image processing competition by contestant Judy Schmidt, NASA said.
