What colour are stars?

If you asked someone what colour stars are, they would probably say white, and they wouldn't be wrong; however, not all stars are white.

Go and take a look at the stars we have been talking about in previous postings; Betelgeuse (top left of Orion), Rigel (bottom right of Orion), Aldeberan (found by the following the imaginary line through the "belt" upwards to the right) and Sirius (found by the following the imaginary line through the "belt" downwards to the left).

Take a good careful look at these stars and in the next posting we'll talk about theirs colours!
