Say cheese! Nasa has shared an image that looks like a face in space smiling for the camera.

The smiley face is actually a galaxy cluster which is around 4.5 billion light-years away from Earth.

Galaxy clusters are the most massive structures in the universe.

The orange eyes are two very bright galaxies. Another white galaxy looks like a nose while what appears to be smile lines are made by an effect called strong gravitational lensing.

Nasa explains this as when galaxy clusters act as cosmic lenses - magnifying, distorting and bending the light behind them.

The image was captured by the Hubble Space Telescope.

The Hubble Space Telescope lives in orbit about 300 miles from the surface of the Earth.

It was named after astronomer Edwin Hubble and was launched in 1990.

The telescope has helped scientists make some key discoveries about our universe, from the confirmation that black holes exist to capturing the farthest star ever seen.

Nasa says the Hubble has made more than 1.7 million observations during its lifetime.
