IN Prof. Runge's article on the spectra of the elements in last week's issue of NATURE (p. 607) he refers to my explanation of double lines in the spectra of gases (“Cause of Double Lines in Spectra,” ...
Yes. Each spectral line corresponds to a specific energy transition related to a particular atom — and thus, element. Astronomers analyze such lines to tell us what celestial objects are made of. In ...
Spectroscopy analyzes light to identify a celestial object's composition. Each element absorbs light at unique wavelengths, creating a spectral "fingerprint". The amount of light absorbed indicates ...
A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has detected radio recombination lines (RRLs) of ions heavier than helium for the first time, using ...
Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across ...
Astronomers observe Type II supernova SN 2024bch behaving differently, with energy from Bowen fluorescence rather than ejecta interaction, challenging models of stellar death and high-energy neutrino ...
