Associating colors with sound, this one sounds like WOW! (Chuck, I don't disagree that colors are perceived by our brains, but I argue that whatever they are like, they exist independently of our brains in definable ways, as shown by our measurements. And we can represent these actual wavelengths by printed colors that we can identify visually.) -- Joe ------------------------------ On Mon, Apr 22, 2013 6:28 AM MDT Chuck Hards wrote:

Wow that is remarkable. I can't recall ever seeing the Horsehead in such detail. And good choice of colors on the part of the people who processed the image. Gives it quite a ghostly appearance.

I know Joe will disagree with me, but color only exists in the minds of some living creatures. It is our way of distinguishing different wavelengths of light energy. The colors you perceive mostly depends on the environment your ancestors evolved in. For the purposes of argument, I'm setting-aside singular mutations and those cases where, due to a difference in brain wiring (for whatever reason, injury or otherwise), some individuals percieve colors associated with sounds, for example, or shapes.

Thanks for calling it to our attention, Kelly!

I think today's APOD will go down as one of my all time favorites! I am blown away by the detail and dimension. It makes me really excited to see what the James Webb sends back in a few years. Maybe I won't miss visual-light images as much as I thought I might.
