Below I merged recently released infrared images of the well-known Trifid Nebula (M20) with a visible image (from NOAO).
Colors are assigned to 3 bands: red = MIPS (24um), green = IRAC (3.5-8um), blue = visible (0.4-0.7um). -------------------- I always think before posting! - Marco -

Few days ago another beautiful Hubble was published:
NGC 5866 tilted nearly edge-on galaxy image from ACS This processing highlight the weakest and brightest details:
Here the sharpened view of the dust disk at full res:

Look at the distant spiral galaxy in the upper left corner of the bottom image!
Does it have a name? -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

I don't know, but as is the case with all ACS galaxy images, there are large numbers of distant galaxies visible behind the target. Which is of course natural, because the universe is quite similar over large distances.
-------------------- The universe is not only stranger than we imagine, it is stranger than we can imagine.
