Very cool. Does anyone know why some areas are somewhat blueish. And what about the very bright stars?

The colors are a bit arbitrary. The sensor that takes these images only records intensity and not color. Different filters are placed over the sensor to record different wavelengths. Not all of these wavelengths are visible light. The colors are a mapping of these wavelengths to the visible spectrum.

This is amazing. When you can zoom in on a bright speck and discover that it's actually a giant cluster of stars, and then continue zooming in on that cluster until it doesn't seem dense anymore, it actually lends context to the static photos of space we've all seen before.

Ok, where do I get the 9 Gigapixel version? :-) P.S. Yes, I know I don't really need that much resolution, but still.

I call bullshit ;-) as at 15" retina is 4Mpix. In a short time span we'll have 20~30" retina)class at that size and they could very well be 9~15Mpix. Of course billion pixels is way too much, but it means that it will scale to the future (I'd love to have a wall-screen with this)

Anyway, multiple links are on the lower part of the rightmost column, available from 1024x768 to full res in a variety of formats.
