SUMMARY: Most stars do not end their existence in a cataclysmic supernova explosion. For example, our Sun is more typical and someday, in the remote future, the location of our local star will look something like this picture of a distant planetary nebula.

Are there other planetary nebula this circular? Very nice image.

Got a nit, though...


These photons can take a million years to travel outward through the overlying matter until they reach the surface and escape into space as visible light.
"Millions of years" is now many thousands, right?


Astronomer Jim Misti produced this exceptional image over three nights in February 2006 using his personal 32-inch telescope...
Wow! Mine is not half that long. ;)

Wow, even after a 4 hour exposure with a big scope that thing is still very dim. Nice view of some galaxies around the edges too!
