Dusty Whirlpool

The iconic Whirlpool Galaxy M51a (NGC 5194) and its companion M51b (NGC 5195) in infrared. I used the same bands as the Cygnus mosaic. The result interests me because it looks similar in coloration to a visible light image, which is not something I expected. Though the colors are similar, the structure is of course very different looking since we are seeing dust. To me it is kind of like looking at the skeleton of a galaxy.

 

Some green halos are apparent due to the WISE data being quite a bit lower in resolution than the Spitzer IRAC4 data.

 

Red: Spitzer/MIPS24 (24μm)

Green: WISE/W3 (12μm)

Blue: Spitzer/IRAC4 (8μm)

 

North is up.
