Sunspot AR3256 erupted with an X1.2-class solar flare. NASA's Solar Dynamics Observatory captured the fireworks in multiple ...

Dark storm clouds greeted many Southeast Texas residents on Halloween morning, but some people woke up to an eerie yellow hue ...

"And we use lots of different sizes of particles, because sunlight has different colours at the different wavelength." How much each particle scatters light depends on its size, "so we ...

And because blue wavelengths are the shortest, they get scattered more, resulting in a blue sky. During a sunset, however, light scattering works differently. The sun’s light has a lot further ...

Violet is a single wavelength close to 380 nm, at the limit of what our eyes can see. If the sun produces white light, why do we see any colors in the sky at all? The reason is that when an ...

This image, taken at 2.2 micron wavelength, shows the main ring system in reflected sunlight. This particular wavelength was chosen since Uranus itself is dark, since methane gas in its atmosphere ...

In this comprehensive review of the radio astronomy of the Sun, thirteen researchers based in Australia summarise our present knowledge of solar radio emission at wavelengths of about one metre. CSIRO ...

"Sunlight is a broad spectrum of wavelengths," said Prof Xiulin Ruan. "We know that each particle size can only scatter one wavelength effectively so we decided to use different particle sizes to ...
