When I looked at todays picture, Orion Nebula in Oxygen, Hydrogen (2013 jun 04) something jumped out at me.

Has any one ever seen the flying eagle, just about in the center of the picture-just a little to the right. You can see the beak, the head, the crest on the chest, the eye, the wings stretched out and high, it even looks like someone is standing on top of the eagles neck riding the skys.

• Not "eagles" exactly:

<<The Sleep of Reason Produces Monsters (Spanish: El sueño de la razón produce monstruos) is an etching made by the Spanish painter and printmaker Francisco Goya. Created between 1797 and 1799, it is plate 43 of the 80 etchings making up the suite of satires Los Caprichos. Goya imagines himself asleep amidst his drawing tools, his reason dulled by slumber and bedeviled by creatures that prowl in the dark. The work includes owls that may be symbols of folly and bats symbolising ignorance. The artist's nightmare reflected his view of Spanish society, which he portrayed in the Los Caprichos as demented, corrupt, and ripe for ridicule. The full epigraph for caprichio No. 43 is: "Fantasy abandoned by reason produces impossible monsters: united with her, she is the mother of the arts and the origin of their marvels.">>

I also wondered what colours applied in the image when I saw this APOD. Thanks to all who have posted so far it seems to be that sulfur is red, hydrogen green and oxygen blue, though there may be some colour mixing. I am therefore confused why in very many APODs that great note is made of the red of hydrogen alpha (Ha) yet sulfur is red here and Ha (if that is what the hydrogen is here) is green. Thanks for any help.

• - Single ionized sulfur (Sii) at 672 nm
  - Hydrogen-alpha (Ha) at 656 nm
  - Double ionized oxygen (Oiii) at 501 nm

The whole picture looks like a Flower about to bloom.

From the Trapezium to the upper right is the flower, and below is the leaves and stem...The "Running Man" Nebula to the left is a Bud....it is like a Rose in Space...Amazing!

The Dust Lane Rift area looks like a fast moving Ice Skater, a blur of motion.
M42 is my most favorite place!!!!!

Pull back on the magnification of your browser and you will see what I mean.

Hydrogen, Oxygen, and Sulfur Gas...but it does not say which colors are which.... OH!! THANKS, ART!!!! So....What is all the Yellow Then????

  Try tweaking the Hue.

Are the pseudo colors specific? Which color is which element?

Typically, sulfur is mapped to red, hydrogen to green and oxygen to blue.
Then to get the Hubble palette, the colors are adjusted some more.

  Oxygen's blue,
