They're false-color so if anything, this says more about our Photoshop choices.
Even better would be to show a large chart of all those images at once, so they could be compared on a large display without needing to scrub a slider back and forth.
With these false color images, it’s impossible to know without careful investigation what the colors in each image represent or how they’re mixed together, and it’s impossible to make useful comparisons.
See the "Multiwavelength Milky Way" poster from NASA: http://mwmw.gsfc.nasa.gov/mmw_product.html#poster They're still false-color and only show the plane of the galaxy, but you can at least see them all simultaneously.
Anyone got an API for this?
