Observations confirmed the presence of which three highly ionized elements in the Veil Nebula's spectral signature?

Answer

Oxygen, hydrogen, and sulfur

The physical mechanism driving the nebula—the hyper-energetic shockwave heating the surrounding material—is spectroscopically verifiable by the light emitted. When the interstellar gas is ionized by this extreme heat, the subsequent recombination and energy level cascades produce light at specific wavelengths that function as a unique elemental fingerprint. Observations from advanced instruments like the Hubble Space Telescope have successfully identified strong emission lines corresponding to highly ionized oxygen, hydrogen, and sulfur within the nebula’s structure. These spectral signatures are key indicators that the gas has been subjected to temperatures far exceeding those found in typical star-forming regions.
