Took an older picture I'd already processed from HST and tried overlaying the x-rays. This supernova remnant has a reddish/cooler x-ray rim with a bluer/hotter interior. Interestingly, the part brightest in visible light, which some call the firefox, is the dimmest part of the x-ray emitting nebula, but also apparently the hottest.
A Hubble-only view that I did a while back is here: flic.kr/p/MqXcQX
The upper left and lower right and a few other smaller places are missing data. I've put some fake data in there to make it less distracting, but it should be just noticeable if one looks closely.

N103B is seen here glowing in nacreous colored x-rays from CXO overlaid upon its visible counterpart from HST glowing red in hydrogen and greenish oxygen emission.
Coincidentally, and wonderfully, a bright planetary nebula is glowing a greenish yellow hue to the lower right, seen against a reddish, larger gaseous emission nebula which surrounds the young double star cluster NGC 1850 that exists just outside the frame.
This is all happening within our small, neighboring galaxy, the Large Magellanic Cloud. We are lucky to have the LMC as there are many neat things to see within it, but it is not so far away that they are too small to make out.

Another supernova remnant from the Large Magellanic Cloud, seen by Hubble and Chandra in visible, near-infrared, and x-ray light. This time I've overlapped two color images together, because I heard you like color so I put color in your color so you can look at color while you look at color.

A supernova remnant in the Large Magellanic Cloud from Chandra, seen in x-ray light.
I did the color filtering differently this time, following the example given on this page: hea-www.harvard.edu/ChandraSNR/SNRJ0534.2-7033/chandra_im...
Truth be told, and I'd never deny it, I still don't really know what I'm doing when I work with Chandra data. I mean, I can smooth it decently, but when it comes to picking and understanding the energy levels to assign colors to, it's not something I know much about.
Anyway, this is not the longest exposure ever, so it's pretty noisy, which you can probably still see despite the attempt at smoothing.
