As soon as sunlight hits our atmosphere, its rays scatter, creating what is known as Rayleigh scattering, named for 19th century physicist Lord Rayleigh. Shorter wavelength light such as blue and violet scatters more than long wavelength light; hence why our sky appears bluer. This phenomenon was named for Lord Rayleigh’s 19th century experiment on…
This week will see the Moon turn red during a lunar eclipse – known as a Blood Moon and unrelated to any strange prophecies or predictions. Today marks one of four total lunar eclipses within two years – an astronomical phenomenon known as a lunar tetrad – occurring over that period. May and October eclipses…
Quora does not moderate any questions asked to it, unlike Wikipedia where volunteers continually proof and correct articles in order to create a reliable information source. Quora simply lacks this feature. Unfairly placing value on questions at the expense of answer authors who spend hours crafting detailed replies would be silly. Quora should devise a…
Have you ever found yourself looking up on a sunny day and wondering why the sky appears blue? Turns out there’s an excellent explanation! The color of the sky is determined by how sunlight interacts with our atmosphere. Sunlight passes through air molecules, scattering in all directions with blue hues being more heavily dispersed than…
Heath McKenzie brings brilliant fun and entertainment to the science of light and colour, starting with his audience-pleasing WHY? question. His illustrations and humor will surely become firm favorites among children of all ages. Sky BLUE took an early advantage, when Kerr sent a pass to Raquel Rodriguez who deftly maneuvered past two Portland defenders…
The sky is actually an intricate mosaic of many colors depending on time of day and weather conditions, with blue being created by sunlight being scattered by particles in the atmosphere – shorter wavelengths like blue tending to be scattered more often than others such as violet. Air molecules scatter blue light, while larger particles…
As sunlight passes through the atmosphere, its energy becomes scattered by air molecules – this scattering effect being especially evident for blue light. As such, very little of the direct blue light of the sun reaches your eyes directly, leading to pale skies as you climb higher into the atmosphere. Sunlight As the Sun shines…
Saturn boasts seven rings, which consist of icy chunks encircling it. They’re named alphabetically from A to G and average only 30 feet or meters high on average. Saturn and its moons exert gravitational pull that creates patterns known as bending waves or spiral density waves in its rings, whereby bands move closer or further…
Oliver Scott of Wombarra Our atmosphere interacts with sunlight to produce blue hued skies on Earth. Blue light scatters more readily than other colours; thus creating its distinct blue color. Sunlight contains all of the colors of the rainbow, which we can see when passing it through a prism. But when the sun is low…
