Samsung "space zoom" moon photos are faked by AI (2023) (reddit.com)
Many of us have witnessed the breathtaking moon photos taken with the latest zoom lenses, starting with the S20 Ultra. Nevertheless, I've always had doubts about their authenticity, as they appear almost too perfect. While these images are not necessarily outright fabrications, neither are they entirely genuine. Let me explain.

Euclid finds complete Einstein Ring in NGC galaxy (euclid-ec.org)
Gravitational lenses are rare in the sky – galaxies bending the light-paths of light from other galaxies behind them to form distorted or even multiple images. Even rarer is a perfect alignment of the two galaxies with us, the obervers, with the light being bent into a so-called Einstein Ring. And the rarest case was now observed by Euclid: this happening in an extremely nearby NGC galaxy.
