Wow!! Our sun is tiny compared to some of those!! Saved that link also!
That got me thinking about the colour of stars again - so far as I remember, they can come in just about any colour, but our atmosphere makes them look the same, with The Jewel Box being the exception. I wonder why - why they are all different colours and why most of them look the same through our atmosphere? I should be able to hunt up some answers somewhere - fascinating stuff!
