I think especially cool are the galaxies that you can see through the nebula.

I wondered what the "smudge" was above the bright star in the horse's brow, thinking maybe it was some kind of reflection or glare. But I zoomed in and I see it's a galaxy. Then I notice that so many of the dots in this photo are galaxies, particularly in the top right portion of the image. Incredible. http://apod.nasa.gov/apod/image/1304/horseheadir_hubble_1225.jpg Thanks Kelly!

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! On Mon, Apr 22, 2013 at 5:46 AM, Kelly Ricks <kellyalenericks@gmail.com>wrote:
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.
