August's full 'Sturgeon Moon' rises this weekend, putting on a spectacular lunar light show as it leaps above the ...

Why is the sky blue on Earth, yet space appears pitch black? This video uncovers the science behind one of nature’s most ...

The sky above Earth is a beautiful radiant blue and we all know why: Rayleigh scattering. The tiny particles in our atmosphere interact with only the blue light coming from the sun.

WHY DOES THE SKY ON EARTH LOOK BLUE? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through.

Rayleigh scattering is what makes Earth’s skies blue by scattering the shorter (bluer) wavelengths of sunlight. Because WASP-79b doesn’t seem to have this phenomenon, the daytime sky would ...

GJ 1214 b’s did not produce strong Rayleigh scattering and, based on previous research on this super-Earth, lead the team of researchers to conclude the planet has a water-rich atmosphere.
