...Agassiz telescope will further explore the second method. Formerly, telescopes could pick out only ionized hydrogen which recombined with free electrons and radiated light in the visible spectrum...
...apparatus, however, can record the energy released by invisible radiation from the neutral hydrogen atom when its single electron does a "flip flop" (reverses its spin). By calculations astronomers can then place the gaseous clouds in their proper position in space...
...addition to tracing hydrogen clouds, the telescope will search for new spectrum lines, especially that of the element deuterium ("heavy hygrogen") and radiation from other galaxies and from...
...Nobel Prize winner Edward M. Purcell, professor of Physics, gave Ph.D. candidate Ewen the research project idea that there might be measurable radiations from the atomic particles of hydrogen floating in the Milky...
...March 1951, Purcell and Ewen announced that these hydrogen clouds radiate at a wavelength of 21 centimenters, and Ewen got his Ph.D. in Physics. The latter still insists, "Purcell provided the brains, I just the brawn...
