- In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines. Each line indicates a particular chemical element or molecule, with the line strength indicating the abundance of that element. The strengths of the different spectral lines vary mainly due to the temperature of the photosphere, although in some cases there are true abundance differences. The spectral class of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere’s temperature.

A 1985 film directed by Terry Gilliam, depicting one man’s futile struggle against a futuristic (and heavily decayed) governmental bureaucracy, drawing very heavily on George Orwell’s 1984. Stakes a serious claim towards being the most definite and ghastly example of Executive Meddling in the entire history of cinema. If you’re not watching the director’s cut, you’re not watching the real thing.
