WebThis is called ionization. At the beginning of the Cosmic Dawn – during the Universe’s Dark Ages – nearly all of its hydrogen was electrically neutral, with a proton and an electron bound together. But stars – at least those much more massive than our own Sun – produce a great deal of ionizing light, and can tear these atoms apart.

WebThe energy levels of an ionized atom are entirely different from those of the same atom when it is neutral. Each time an electron is removed from the atom, the energy levels of the ion, and thus the wavelengths of the spectral lines it can produce, change. This helps astronomers differentiate the ions of a given element. WebHot but thinner clouds of ionized hydrogen near hot young stars. Interstellar dust: it obscures our view. Short wavelength radiation is blocked by dust where long wavelength is not, so IR telescopes often used for ‘looking through’ obscured areas.) Interstellar gas mostly resides in about 2% of interstellar space, called interstellar clouds.
