Space Telescope, the "supersonic exhaust from [planetary] nebula M2-9." This is an example of a "bipolar planetary nebula" and is estimated to be ten times the diameter of Pluto's orbit. This
picture, along with others, contributes to astronomers' understanding of the complex processes that can result from the death throes of Sun-like stars. The site contains the M2-9 photo in several resolutions and formats, an explanatory caption, a photo gallery of other planetary nebulas, a QuickTime movie illustrating the process, and other explanatory material.
