Take pictures of smiling faces in the universe

The Hubble telescope captures a picture of a group of galaxies shaped like a smiley.

According to Live Science, the galaxy cluster is named SDSS J1038 + 4849 . It has two bright dots that look like eyes, white dots, light curves that form the mouth and contour of the face.

According to Einstein's general theory of relativity, giant objects can actually bend the space around them. If light passes through this space, it will be diverted, amplified or deformed, as if passing through a lens. In this case, the galaxy cluster and distant light sources are aligned with the Hubble telescope. Two bright "eyes" are two galaxies located far away from each other.

The cluster of galaxies is one of the largest objects in the universe, able to create attractive lens effects. This astronomical phenomenon occurs when light emitted from an object is deflected on the way, under the influence of gravity when approaching other celestial bodies. The light was bent by gravity around it, creating a giant smile-like circle.

Astronomers look for signs of gravitational lenses to identify giant objects that are not visible such as black holes, galaxy clusters or dark matter.
