Licensing[edit | edit source]

Description	Recent Chandra observations have revealed new details about the fiery ring surrounding the stellar explosion that produced Supernova 1987A.
Source	The image appears on a website entitled, "Supernova 1987A: Fast Forward to the Past" at url=http://chandra.harvard.edu/photo/2005/sn87a/.
Date	9 January 2005
Author	S. A. Zhekov, R. McCRay, K. Borkowski, D. Burrows, and S. Park
Rationale	No free licensed or public domain alternatives known to exist to show the shock wave as it hits the edge of the cavity, where it would encounter the much denser gas deposited by the red supergiant wind, and produce a dramatic increase in X-radiation.
Permission	Fair Use, NASA images are usually Public Domain, but S. A. Zhekov, R. McCRay, K. Borkowski, D. Burrows, and S. Park may not have agreed to this.

Metadata

This file contains additional information, probably added from the digital camera or scanner used to create or digitize it.

If the file has been modified from its original state, some details may not fully reflect the modified file.

Image title	The Chandra X-ray image (left) reveals a ring of multimillion-degree gas produced by the collision of an outward-moving supernova shock wave with a ring of cool circumstellar gas. The optical image (right) from the Hubble Space Telescope shows a ring of bright spots that are also caused by the shock wave hitting the cool gas. Long before the explosion of the massive star that produced Supernova 1987A, most of its outer layers expanded away in a slowly moving stellar wind that formed a vast cloud of gas. Later, a high-speed wind from the star carved out a cavity about 1 light year in diameter in the cool gas cloud. As the supernova shock wave plows deeper into the cool cloud the ring should become larger and much brighter in both optical and X-ray light.
