Took me a while to do that. I hope that you like what I did.
In some respects, I am not happy. I wanted to fit much, much more info. But I saw very soon that that was not going to be possible, at least in the way in which I originally conceived the infographic.
Adding more information without cluttering up too much would surely ask for a change in format. I tried to keep it as simple as possible.
In addition, my original idea was quite different from this. I had in mind something more hand made, more organic. However I also wanted to try Illustrator out, which gives a different feeling. At least in my hands.
Only one explanation is pertinent:
I used the greek letter Tau to represent optical depth, which is a measure of opacity (see also Stellar Atmospheres).
Other symbols are more obvious. L stands for luminosity, T is temperature, D is deuterium, H is hydrogen.
If you are looking at this, I’d truly appreciate your opinion about the infographic.
