Circinus Galaxy in infrared, with WISE

The WISE satellite has imaged the Circinus galaxy in the near infrared. This massively reduces the very substantial extinction of the light from this obscured galaxy that is caused by the intervening dust from our own Milky Way galaxy.

Here is the image:

The coding of this image is as follows.

Blue+Cyan+Green+Red

codes for:

3.4 microns ; 4.6 microns ; 12 microns, 22 microns

As a famous lady infrared astronomer said:
"I don't care if it's plastic, as long as it is in the near-infrared and I can see it!"
(referring to the ability of near-infrared imaging to reduce the dust extinction of light caused by the interstellar medium of our own Galaxy, by a factor of 10 or more.)
