by the colour of the sun. each color on stars is due to its temperature. Scientists observe the colour of the rays emmitted (including infra-red rays) and thus are able to determine the temperature.

with the help of radiation pyrometry, it being distant approach of measuring that based on the assumption of black physique radiation. whilst some thing is heated at larger temperatures, its shade variations with the help of going to larger & larger temperature from black to crimson to yellow & white. shade matching with a heated twine or textile helps in measuring distant temperatures with the help of conserving distant warm textile interior the backgraoud.

A hot object radiates heat, and the frequency (color) it gives off varies with the temperature.
We see it here on earth, metal can be heated red hot, or white hot.
Anyway, with clever measurements one can deterimine the temperature.
