when they are BILLIONS of miles away? Always puzzled me.

This is a normal post Lots of VERY clever super nerds
have been working on this for yonks.

This is a good place to start:
en.wikipedia.org/wiki/Stellar_structure

Basically, it's a load of extrapolation about whats going inside the sun - it's occassionally probed with x-rays etc:

soho.esac.esa.int/

This is a normal post You can tell (or deduce I guess)
a whole lot from the light spectrum of a star, it's relative brightness, how far away it is, and what else is nearby.

That withstanding, it's still completely mid boggling that they can do it anyway.
