The aftermath of the death of a massive star is shown in beautiful detail in this new composite image of G292.0+1.8. In color is the Chandra X-ray Observatory image - easily the deepest X-ray image ever obtained of this supernova remnant - and in white is optical data from the Digitized Sky Survey. Although considered a "textbook" case of a supernova remnant, the intricate structure shown here reveals a few surprises.

Dr. Patrick Slane from the Chandra X-ray Center recently shared some information on the G292.0+1.8 supernova remnant with NASA's museum alliance. We think you'll find it useful too:

Well, it's finally time for us to dip our X-ray toe (yes, we claim all things high-energy) into the world of blogging. This current incarnation is our attempt to work out the technology while we experiment with content. The plan is to include such topics as the most recent image or press release, new innovations on the website, and the latest in our formal education efforts.

This messy collision of galaxy clusters is about 2.4 billion light years from Earth.
