Artificial Night-Lights Are Growing, Getting Brighter

By Neha Jain @lifesciexplore As soon as it gets dark, street lights, which have become widespread in the developed world—and are rapidly expanding in the developing world—are switched on. Indeed, since the second half of the twentieth century, Earth has become brighter at night. Now, new satellite-based research shows that our outdoor artificial night-lights are still spreading to more areas on Earth and have gotten brighter over the past few years. How night-lights impact the world Outdoor lighting is regarded as a necessity, especially in highly populated areas, but artificial…

Sunsets: Sunset seen at the coast in Novigrad, Croatia. Thin clouds turn a normal sunset into a sci-fi worthy sunset. [EOS 7DmkII: 400mm, f5.6, ISO 100, 1/2000 sec] Photos Science & Art 

Sunsets are Illusions

By Steven Spence “It is sometimes said that scientists are unromantic, that their passion to figure out robs the world of beauty and mystery. But is it not stirring to understand how the world actually works — that white light is made of colors, that color is the way we perceive the wavelengths of light,[…] and that the sky is blue for the same reason that the sunset is red? It does no harm to the romance of the sunset to know a little bit about it.” (Carl Sagan, Pale…

First Photo of Light as Wave and Particle

In 1905, Albert Einstein proposed that light has properties of both a wave and a stream of particles. Now, researchers in Switzerland have taken  the first ever photo of light behaving both as a wave and as a stream of particles at the same time. The ability to observe light in this way could bring us a step closer to building super fast quantum computers, the researchers say. When UV light hits a metal surface it causes an emission of electrons. This is known as the photoelectric effect. A research…
