Very nice, Canuck, but, urm, there're quite a few zeros missing from the age, don't you think ?
Thanks much for sharing,

Nope, its age is estimated to be 10600 years (+2300/−1200 years), based on the ratio of its size to its measured expansion rate of 31 km·s−1.[6]
Planetary nebulae are a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives.[2]
ie, these can be pretty young, astronomically speaking that is.
