Many aspects of Saturn’s rings captivate human imagination like few others can, yet astronomers are discovering that their lifespan may be shorter than previously anticipated. Research published earlier this month in Science Advances and Icarus journals suggests that Saturn’s rings are relatively young compared to their cosmic peers; likely having existed for no more than…
Why does the sky appear blue? To answer that question, some basic physics may provide the solution. As soon as light hits the atmosphere, it becomes dispersed into many directions by air molecules — mostly nitrogen and oxygen molecules – mostly through scattering. Shorter wavelengths like blue and violet tend to get scattered more strongly….
As sunlight penetrates Earth’s atmosphere, its light is scattered by gases and particles and becomes visible as blue hues are more dominant than others. Though its plot may be predictable and its characters recognizable, The Sky Blues succeeds in providing an inclusive queer narrative with clear beats and authentic teenage characters – it should definitely…
Early Wednesday morning, the Moon suddenly lit up red like an extravagant rosebud in the predawn sky for an extended period – an unprecedented celestial event known as a super blood moon eclipse. Lunar eclipses begin when the Moon enters Earth’s outer shadow, the penumbra, before moving further inward and entering its darker umbra. What…
As sunlight enters Earth’s atmosphere, its light is scattered by oxygen and nitrogen molecules present. Shorter blue wavelengths tend to be scattered more than longer red ones resulting in the sky taking on its signature hue. At dawn and dusk, sunlight must travel further before reaching our eyes; more blue wavelengths scatter into the atmosphere…
Sky color is determined by gas molecules in our atmosphere, predominantly nitrogen and oxygen molecules, that scatter light in all directions, with blue wavelengths being dispersed more strongly than red ones. Rayleigh scattering is the name given to this process of light dispersion through atmospheric diffusion, making sunlight appear redder nearer the horizon (for example…
Skys that change color from deep blue near the horizon to white near it are often due to dust or suspended water particles in the air, or indicate higher humidity. As sunlight travels through our atmosphere, it interacts with air molecules which scatter its light like billiard balls – blue and violet wavelengths being scattered…
Bluesky is a social network similar to Twitter but not owned by Elon Musk. Despite still being in its early stage of development, Bluesky boasts a substantial user base. Air particles in our atmosphere are smaller than the wavelengths of light, meaning they scatter blue light more readily than any other color – giving the…
At noontime, the sky appears blue due to molecules in the atmosphere scattering blue light more efficiently than red. At sunrise and sunset, however, its color changes to red due to light having made its journey through an extended path through our atmosphere. There are various explanations as to why the sky is blue; some…
