NASA astronomers have noticed an unusual stellar formation in space. If you look at the photo taken by the Hubble & # 39; telescope, you will see a "smiley face".

This unusual star formation belongs to the cluster of galaxies SDSS J0952 + 3434.

As NASA astronomers have explained, this arc-shaped galaxy has this shape because its light passed near a massive object, resulting in distortion and extension like a smile.
To improve the image quality, NASA employees increased the image resolution of the Wide Field Camera 3 broadband camera.
Such images are valuable to scientists because they allow us to better understand how stars are created in the cold corners of the universe.
