- There was a man who lived a life of fire.
- Even upon the fabric of time,
- Where purple becomes orange
- And orange purple,
- This life glowed,
- A dire red stain, indelible;
- Yet when he was dead,
- He saw that he had not lived.
- Stephen Crane: There was a man who lived a life of fire from The Black Riders and Other Lines, 1895
Composite image of the SN 1006 supernova remnant, located about 7000 light years from Earth. Shown here are X-ray data from NASA's Chandra X-ray Observatory (blue), optical data from the University of Michigan's 0.9 meter Curtis Schmidt telescope at the NSF's Cerro Tololo Inter-American Observatory (CTIO; yellow) and the Digitized Sky Survey (orange and light blue), plus radio data from the NRAO's Very Large Array and Green Bank Telescope (VLA/GBT; red). This combined study of the Chandra, CTIO and VLA/GBT observations shows new evidence for the acceleration of charged particles to high energies in supernova shockwaves. A twisting ribbon of light seen by Hubble reveals where the expanding blast wave is sweeping into very tenuous surrounding gas: X-ray: NASA/CXC/Rutgers/G.Cassam-
