Some of these lines coincide closely with lines of the series observed by Pickering in the spectrum of the star ς Puppis, and attributed to hydrogen in consequence of its simple numerical ...

WITH the continuous spectrum described by Lyman (Astrophysical Jour., 60, 1) as a background, and with hydrogen flowing through the receiver of the spectrograph, it was found possible to ...

Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...

According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic ...
