There’s a saying that goes “Smile, and the world will smile back”. In this case it was the universe that smiled back, as the Hubble Space Telescope photographed deep space galaxies.
The smiley in the photo appeared thanks to a cosmic lens which was created due to warped spacetime (English explanation below).
Photographed at least three years ago, The Hubble team processed the photo after the smiley face was spotted during a public contest.
