[quote="Anita_Head":bf3b3]I would like to know how they measure the temp of the sun and nukes.[/quote:bf3b3]

using spectrography or whatever its called. you use a spectrograph hooked up to a telescope to measure its wavelength on the spectrum. (gamma rays, x rays, radio waves, visible light) these are all light sources. the only difference is we can only see a narrow band of it.

take a picture of the stars spectra. analyze it. different colour stars have different temps. If the spectra analysis shows the majority of light being given off is gamma or x rays, the star is reall hot. this would show up as blue to us. if a star gives off a lower frequency, it will be red. these are dwarf stars and are not hot enough to produce large amounts of energy.

thats my really confusing shitty way of explaining it.
