Hubble telescope recently photographed a unique image of the galaxy cluster SDSS J1038 + 4849. The image looks like a smiling face pattern with two bright spots for eyes, one point in the middle as the nose and round arches.
The image actually looks more like a Halloween pumpkin icons. Bright dots that is a collection of galaxies is billions of years of Earth.
According to astronomers, the point of the 'eye' was 2 pieces of galaxy at a certain distance and the curved lines around it is a bent of light due to gravity galaxies are nearby. Curved light effects due to gravity is known as 'gravitational lensing'.

In Einstein's theory of general relativity, the massive objects as galaxies can bend the space around them. When light passes through this curved region, the light can be directed, enlarged or distorted, as well as the light passing through ordinary lens.
And Cluster Galaxies or collection of galaxies with distance close enough in theory able to bend the space around it so that makes light look like a lens effect. *** [EKA | FROM VARIOUS SOURCES | SPACE]
