At night, the sky is dark blue due to atmospheric scattering of sunlight. Blue light scatters more readily than red light due to shorter wavelengths being more easily diffused into space. Answer is straightforward physics: as the Sun gets lower in the sky, more of its light passes through your atmosphere to reach you – […]

Not many can resist admiring a picturesque blue sky, yet few understand why its hue comes about. No, it doesn’t come from oxygen levels in the atmosphere or because sunlight emits blue rays; there’s another explanation. Light that reaches Earth’s atmosphere is scattered by gases and particles in the air, with blue wavelength light being

Everyone appreciates a lovely blue sky on a bright day, yet many savvy individuals have puzzled over why it should be that color. Rayleigh scattering, which occurs when light hits gases and particles in the atmosphere, accounts for this phenomenon. Light with shorter wavelengths such as blue is scattered more readily than other colors. Rayleigh

Blue has long been thought of as making the sky appear clear and blue, but this effect is actually caused by gases and particles in our atmosphere. They scatter shorter wavelengths such as blue light more readily than their redder counterparts, producing that hue. Many people believe the ocean’s hue reflects the sky, but in

Saturn’s rings have long been an object of fascination. Viewed straight on, their thin outlines can be seen. Earth passes through the plane of Saturn’s rings every 13 to 15 years and views them edge-on at one of Saturn’s equinoxes, providing us a rare view. It doesn’t signify an impending disaster for our planet, but

When kids ask the age-old question “why is the sky blue,” try this simple science experiment that draws upon John Tyndall’s work from Ireland in the 1860s. Tyndall used a clear tube and smoke particles to demonstrate how blue light scatters more than other colors; this phenomenon explains why our atmosphere gives the sky its

Apollo astronauts had successfully explored and collected rocks that are still used by scientists today; but NASA managers knew this program could no longer continue. NASA Administrator Thomas Paine had to make some hard choices due to tightened budgets and decisions taken over the last two years. Politics The Apollo program was an ambitious undertaking
