Director Todd Douglas Miller employs an incredible archive of footage to transport us back 50 years. It serves as an ode to America’s ambition and serves as a reminder of what can be accomplished when we set our sights high. He accomplishes this without narration, instead allowing the astronauts and their crew to communicate directly […]

As sunlight passes through the atmosphere, its light becomes scattered by air molecules. Light with shorter wavelengths such as blue is dispersed more widely than other colors such as red. Rayleigh Scattering causes this effect and gives the sky its signature blue hue, particularly nearer the horizon. The Sun Light travels through Earth’s atmosphere before

Sunlight travels through Earth’s atmosphere where it is redirected by gas molecules and small particles into various directions, with blue wavelengths becoming scattered more readily than others, giving the sky its characteristic color during daylight hours. Sunrise and sunset sunlight must pass through more of the atmosphere, leading to more blue being scattered away and

Have you ever looked up at a stunning blue sky and wondered why its hue was blue? That isn’t surprising as sky color results from complex interactions among air molecules. Simple explanation: Because oxygen and nitrogen molecules are significantly smaller than light wavelengths, they scatter it more strongly resulting in blue light being scattered more

Saturn’s rings are one of the most breathtaking sights in our Solar System, yet over cosmic timescale they are rapidly dissolving away. NASA scientists have confirmed in a new research article published in Icarus journal that Saturn’s iconic rings are being pulled into its gravity as an ever-increasing cloud of dusty ice particles, according to

When sunlight hits the atmosphere it scatters. Blue wavelengths tend to disperse more quickly than any other colour; that’s why the sky looks bluer. At sunrise and sunset, when the Sun is low near the horizon, its light must travel further through the atmosphere before it can reach you. As such, shorter wavelengths such as

As sunlight passes through the atmosphere, its wavelengths (color) are scattered by air molecules into all directions, with blue wavelengths being scattered more strongly than others – hence why the sky appears bluer. Atmospheric oxygen is provided to us by microbes known as cyanobacteria through photosynthesis; they produce water and carbon dioxide which plants turn
Why is the Sky So Blue? Read More »
The sky is blue because sunlight that strikes Earth’s atmosphere scatters into all directions. Rays with shorter wavelengths (such as blue and violet ) tend to get scattered more readily than longer ones like red or orange. Your eyes are most greatly stimulated by blue-tinged light. Other colors provide only partial stimulation and appear less

Why Is The Sky Blue? Our atmosphere scatters light in all directions; air molecules and gases contribute to this scattering process, with blue becoming more often visible due to how light is scattered in this way than any other color. C. V. Raman provides us with this explanation in his excellent book entitled Why Does
