I know that HN isn't big on pretty photos.. But these are really pretty - and I certainly learnt from the descriptions (THe asteroid collision and the 3 trillion kilometre collapsing red giant). Does anyone know what type of gear you need to take a photo of the sun like that? I can't imagine it's good for the sensors of my SLR.

To take photos like the image of the Sun in that article you need a telescope coupled with a Hydrogen Alpha filter, mounted to your SLR body. Hydrogen Alpha filters are rather expensive, unfortunately. Take a look at this Wiki article: http://en.wikipedia.org/wiki/H-alpha#Filter http://en.wikipedia.org/wiki/H-alpha#Filter
