NASA’s Perseverance Rover Sends Stunning Images of Mars

Since landing on Mars on February 18, NASA’s Perseverance rover has sent back some amazing images from around its landing site, Jezero Crater, a 30-mile wide impact depression just north of the Red Planet’s equator. BBC shares a selection of the pictures sent from the mission, “as Perseverance hunts for signs of past microbial life, seeks to characterize the planet’s geology…

Photon-photon polaritons: the intriguing particles that emerge when two photons couple

Scientists at the University of Bath in the UK have found a way to bind together two photons of different colors, paving the way for important advancements in quantum-electrodynamics—the field of science that describes how light and matter interact. In time, the team’s findings are likely to impact developments in optical and quantum communication, and precision measurements of frequency, time and…
