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 ...

Astronomers have uncovered a discovery that could reshape our understanding of the early Universe. Using the James Webb Space ...

What makes it so strange are its spectra, which showed a large spike in Lyman-alpha, or the hydrogen emission line. While stars are made of hydrogen – so this might not seem too weird – this ...

Free-bound emission, linked to hydrogen recombination, dominates the spectra of galaxies like 9422. Free-free and two-photon emissions typically remain subdominant due to insufficient ionizing ...

The resulting spectrum confirmed the redshift to ... identified as the Lyman-α emission radiated by hydrogen atoms. This emission was far stronger than astronomers thought possible at this ...

according to a paper by [Jack Phelps] titled “Galactic Neutral Hydrogen Structures Spectroscopy and Kinematics: Designing a Home Radio Telescope for 21 cm Emission“. The hardware pipeline ...

A biohybrid system combines polymer nanosheets with E. coli to improve hydrogen production by capturing near-infrared light from the solar spectrum.
