Gustav Kirchhoff had written in 1859 that if you could look at the spectrum ... that Helium could exist in the Sun, but not on Earth or any other planet. Janssen's yellow emission line turned ...

Strong emission lines of helium and the first detection of such ... Department of Astronomy and co-author of the paper. "As were spectra from the large Keck telescope on Hawai'i that immediately ...

The spectrum of an active galactic nucleus (AGN) shows characteristic "emission lines" at specific wavelengths corresponding to the most common elements such as hydrogen and helium. These emission ...

However, several experiments surprisingly observed changes in the powerlaw spectral indices γ for protons, helium and heavy nuclei. Specifically, the spectra of GCRs become harder by ∆γ ‘ 0.1−0.2 at ...
