Researchers have measured the brain’s faint glow for the first time, hinting at a potential role of “biophotons” in cognition ...

What are the highest energy photons (gamma rays) emitted by the Sun? Our star is powered by nuclear fusion and these reactions release energy on the order of megaelectronvolts, so naïvely, I would ...

Solar sails represent one of the most elegant concepts in space exploration: using sunlight itself to propel spacecraft ...

With the weather finally warming up and tempting people to get outside, a dermatologist is sharing a reminder to protect our ...

Writing in Physical Review Letters, An et al. present a search for proposed dark-matter particles called dark photons using radiation from the Sun (H. An et al. Phys. Rev. Lett. 134, 171001 ...

Deep in the sun's core, nuclear fusion converts hydrogen to helium, which generates energy. Particles of light called photons carry this energy through a spherical shell called the radiative zone ...

Every morning you see the Sun - but what’s actually happening ... In this visually stunning journey, we trace the photons from core to eye. Discover how something so distant controls everything ...

But one interesting thing the atmosphere does is scatter sunlight: photons from the sun hit molecules of nitrogen and oxygen in the air and bounce off. Many of those photons wind up caroming ...

How Do We Study the Sun? Mostly, the Earth's atmosphere blocks out photons with a shorter wavelength than ultraviolet light. This makes it difficult to study the Sun's inner workings from Earth ...

The James Webb Space Telescope has captured a mid-infrared picture of Sagittarius A*, filling in a long-standing gap in ...

The Planetary Society’s LightSail 2 is a winner of the 2024 Gizmodo Science Fair for testing the feasibility of using photons from the Sun as a form of propulsion for satellites. Can solar ...
