Anyone have any idea what those 'scars' are that are only visible in x-ray wavelengths? I'd try and find out myself, but I'm not qualified enough to even know where to start looking or what to look for. :/
To me the Xray was the most surprising. Where's all that XRay come from? Is it like the microwave radiation where it's left over from the Big Bang? And like you said, where do the scars come from?
I have a reasonably fast connection, but the experience here is greatly improved by downloading all the datasets: http://blog.chromoscope.net/download/
