Superheavy discovery: oganesson is named after the Russian-Armenian physicist Yuri Oganessian. In 2002, a team of Russian and American scientists created the first ever atom of oganesson, which is the ...

This spread-out light is called a spectrum. Every element — and combination of elements — has a unique fingerprint that astronomers can look for in the spectrum of a given object.

I THINK Lecoq de Boisbaudran was the first who called attention to the fact that the line spectra of the elements are by no means so irregular as they seem to be at first sight. He discovered the ...

Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light. Hot ...

Over time, that heavy element–enriched debris rained down on the white dwarf, polluting the atmosphere. Many of these white dwarfs are old but still show this signature of debris in their spectra.

Spectra are specific sets of colors emitted by different atomic elements. ... and advances in the field require detailed knowledge of the atomic spectra of elements in the extreme ultraviolet.
