The sky is an ever-present presence that hosts natural phenomena such as clouds and rainbows, as well as birds, insects, aircraft and kites – not forgetting human creations like aircraft and kites! Additionally, its effects can also be felt through pollution such as smog or light pollution. Pakistanis refer to color as rang (rng). Different…
Saturn’s beautiful rings disappear for brief periods every 29.5 years due to the planet’s axial tilt. Saturn’s inner rings are rapidly dissolving at an alarmingly rapid rate, so much so that an Olympic-sized pool rains down on its upper atmosphere every 30 minutes. Astronomers have noted this trend since the 1980s; unfortunately it’s causing the…
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…
Answering this question is more complex than simply saying it looks blue. Sunlight passes through the atmosphere and is dispersed into all directions by air molecules; shorter wavelengths like blue light tend to be dispersed more strongly by these air molecules than longer ones such as UV. As such, this is why the sky appears…
When we gaze upon the sky, its color usually appears blue. This hue comes from light being scattered by molecules in our atmosphere. Blue wavelengths tend to get scattered more, making them appear brighter than their longer-wavelength counterparts. Other colors may also appear differently depending on factors carried through the air such as weather or…
