Liquid crystals that change colour using only light

Abstract

Changing the colour of a crystal using light alone, without the need for electrical fields or mechanical parts. This is exactly what our team of researchers has achieved by demonstrating a novel method for controlling 3D blue phase photonic crystals.

People have just begun capturing a fascinating film: the most sophisticated time-lapse recording of the night sky

Abstract

On the night of June 30, a large survey telescope designed to map the ever-changing universe began full-scale operations at the Vera C. Rubin Observatory in Chile. This marks a major shift in how we gather knowledge about our planet’s immediate and distant surroundings. Over the course of three nights, the telescope captures images of the entire southern sky—and it will repeat this process for ten years. As a result, we will obtain an astronomical amount of data and records of what changes in the sky and how. This will allow us to explore the universe in ways that were previously inaccessible to us.
