Supernova Remnant N103B & Planetary Nebula
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.
Hubble data from the following proposals were used to create the image:
Red: .10-.90 keV
Green: .90-1.20 keV
Blue: 1.20-10.0 keV
