Data Goes Unscathed Through Turbulent Air Using Light Topology

Researchers demonstrated a world-first method to transmit optical data through open air without distortion-correction hardware by encoding information in the light's topology using skyrmions. In real-world tests over hundreds of meters, the topologically encoded beams retained data with ~98% fidelity under normal conditions and about 86% under extreme turbulence, suggesting cheaper, more robust long-distance optical links and potential applications in space, satellite downlinks, and bridging the digital divide.

Vera Rubin Observatory: Revolutionizing Earth-Based Astronomy in 2025

Researchers at Johns Hopkins have developed a new mathematical algorithm called ImageMM that significantly improves the clarity of images captured by ground-based telescopes by effectively correcting atmospheric distortions, potentially rivaling space telescopes in image quality while maintaining the ability to survey large areas of the sky.

Atacama Desert illuminated by lasers.

The Very Large Telescope in the Atacama Desert, Chile, uses powerful lasers to create artificial stars by making sodium atoms in the atmosphere glow, allowing the telescope to correct for atmospheric distortion and capture sharp images of real stars. The telescope has been involved in key research, including studies of the supermassive black hole at the center of the Milky Way, since its first images were obtained 25 years ago.
