Optical illusions occur naturally in different habitats and conditions across the world. Cloud formations can sometimes make it seem like there's an ocean or a UFO in the sky. Whether it is salt flats ...

The science behind natural optical phenomena—colors in the sky, rainbows, halos, coronas, iridescence, glories, glitter patterns and auroras—will be the topic of a free talk at Rochester Institute of ...

Researchers have experimentally realized an optical effect predicted over 75 years ago: the Tellegen effect, where electric ...

Earth's passage through the plane of Saturn's rings, occurring roughly every 15 years, causes the rings to appear nearly edge-on. The next such event in March 2025 will be poorly observable due to ...

In a study published in Reports on Progress in Physics, researchers have achieved device-independent characterization of genuinely entangled subspaces (GESs) in both optical and superconducting ...

A new study explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable ...

Magneto-optical effects in plasmonic nanostructures represent an exciting frontier in the convergence of photonics, nanomagnetism and materials science. By harnessing the strong local electromagnetic ...

JACKSONVILLE, Fla. — A optical illusion appeared off the First Coast this week, making it seem as though a ship was hovering above and out of the water. The phenomenon, known as a superior mirage, ...

Everyone loves an optical illusion — even if they leave us completely stumped — and they're all around us in the natural world. From an underwater waterfall in the Indian Ocean to a surrealist scene ...

Scientists at Paderborn University have made a further step forward in the field of quantum research: for the first time ever, they have demonstrated a cryogenic circuit (i.e. one that operates in ...
