"You'd see this structured—almost like a patch—grey-toned or white toned-emission connected to the aurora," said researcher Emma Spanswick.

The white light LED has a broad spectrum so one can explore a larger ... In this example I’ve loaded in two images, a photo of a CFL spectrum and a photo of the emission spectrum of quinine sulfate.

Spanswick says the white patch has been ... a renewed interest in continuum emission with the discovery and observations of the long, glowing ribbon of purple light known as STEVE—or Strong ...

According to research published in Nature Communications, the white streaks were first identified by scientists at the University of Calgary using the Transition Region Explorer (TREx) mission. TREx, ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

This grey-white light has long been observed by ... on a timescale of minutes less), and their spectra contain distinguishable auroral emission components, indicating that auroral energy ...
