This writes Science Alert.
This unusual star formation belongs to the galaxy cluster SDSS J0952 + 3434.

As NASA astronomers explained, this arc-shaped galaxy has this shape because the light passes through a large object, so the results become distorted and stretch like a smile.
To improve image quality, NASA staff increased the image resolution of a broadband camera Wide Field Camera 3.
Such images are very valuable to scientists, because they allow a better understanding of how stars form in the cold corners of the universe.
