Thought some of you might like to play with this tool. Works in a browser. Is part of a study on galaxies, I think. There is a lot here. [nottingham.ac.uk]
Doesn't seem to work on my phone and my computer died yesterday, but I'd imagine it's very interesting. Hopefully I'll remember to look at it later
It is cool as this is a project where one can see exactly what the astronomers are seeing out there. I am using an android device and it seems to work well, at first I thought it would not but it worked.
