Have you ever noticed the gorgeous sky this week and wondered why its hue is blue? Well, it all boils down to some science involving physics and chemistry. Sunlight passing through Earth’s atmosphere is scattered by airborne particles and molecules, particularly gas molecules. Shorter wavelengths of light scatter more easily than longer ones, hence making…
As sunlight passes through Earth’s atmosphere, its light is scattered by gases and particles – particularly blue wavelengths which tend to be dispersed more efficiently than other colors resulting in beams with bluish tints. Scientists had difficulty pinpointing why the sky appears blue. Its color can be explained by how small molecules scatter sunlight. Sunlight…
On Tuesday morning, astronomy enthusiasts from Asia, Australia and North America witnessed the Moon slowly become darker until its full eclipse became visible; otherwise known as a blood moon. This event would mark the last total lunar eclipse until 2025. An appearance of a blood moon occurs when direct sunlight is blocked and its light…
People often mistakenly believe that the sky’s hue comes from ocean waves; however, this is incorrect: its hue results from how atmospheric molecules scatter light and reflect it back onto Earth’s surface. Light passing through the atmosphere tends to scatter more readily in blue and violet wavelengths due to their frequencies being closer to those…
Answer: Oxygen and nitrogen molecules in the atmosphere scatter sunlight incoming, with blue wavelengths being scattered more often than red ones resulting in the sky appearing bluer than usual. But this explanation doesn’t explain why the sky doesn’t turn violet at sunset or why Martian skies have an earth-tone hue; that is because sunlight must…
Blue skies may seem to appear every day, but have you ever stopped to think why this happens? The answer lies within light’s path through our atmosphere. When sunlight reaches our atmosphere, it rebounds off gas molecules and scatters in all directions – blue wavelengths tend to disperse more easily than other colors. Rayleigh Scattering…
Saturn’s rings have long held a special place in our imaginations, but our view may soon become restricted by atmospheric obstructions. NASA’s Cassini probe has unveiled surprising evidence indicating that Saturn’s rings may not have endured nearly as long as previously thought. The Age of the Rings Astronomers have long speculated on how Saturn’s rings…
Discover Urdu colors through this lesson and expand your vocabulary while communicating more effectively with people from across the globe. The sky appears blue due to light being scattered by gases and particles in the atmosphere; blue light scatters more readily than other colors, giving it its distinct hue. Scattering of light The sky’s characteristic…
As sunlight passes through the atmosphere it gets refracted or scattered by air molecules; light nearer the blue end of the spectrum tends to get scattered more than other colors, giving a blue hue to the sky. At sunrise and sunset, light traveling through longer distances in the atmosphere becomes less scattered, allowing more red…
