Chromosphere: surrounding the photosphere, invisible to the eye. Irregular layer of gases that extends up and away from the photosphere. Oblate: an equatorial diameter greater than that between the poles of rotation. Spectroscopy: the measurement and analysis of energy spectra to determine the composition of matter, Spectrometer/spectrograph: records the spectrum of light emitted (or absorbed) by a given material, where the light used determines the chemical composition of a substance because elements emit unique and characteristic wavelengths of energy. Prominences: arcs of gas that begin on the bright surface and soar up to 10,000 km into the corona. Flares: (more dramatic than prominences) short-lived gas eruptions lasting up to several hours, usually 20min.
