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

A set of five gas discharge tubes are arranged such that when they are touched with a Tesla coil, their characteristically colored emission spectra are seen. The Tesla coil can burn your skin on ...

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 ...
