“And what of that other unknown element we find glowing green in the far-flung nebulae — green as that we had just passed through — and that we call nebulium?”
“And what of that other unknown element we find glowing green in the far-flung nebulae -- green as that we had just passed through -- and that we call nebulium?”
“The gas "nebulium," not yet found on the earth, is the most characteristic constituent of irregular nebulæ.”
“And what miracles are there in coronium and nebulium which, as the child of nebula and sun, we inherit?”
“When this nebula is observed with a slitless spectrograph the hydrogen and nebulium components are seen as circular discs, but the hydrogen discs are larger than the nebulium discs.”
“In other words, the hydrogen forms an atmosphere about the central star which extends out into space in all directions a great deal farther than the nebulium discs extend.”
“The 37726A line, like the nebulium line, is unknown in stellar spectra; it seems also to be confined to true nebulosity.”
“The bright lines of nebulium have never been observed in a true star: they and the radiations in the ultra-violet known as at”
“Many of the nebular lines are due to hydrogen, others are due to helium; but the majority, including the two on the extreme right in Fig. 13, which we attribute to the hypothetical element nebulium, and the close pair on the extreme left, have not been matched in our laboratories and, therefore, are of unknown origin.”
“As soon as the stellar state is reached nebulium is no longer in evidence.”
