Nah, he wants to claim to be older than Methuselah in another 5 yrs or so.

You say that the nebula has lasted 150,000 years, a cosmic blink of an eye compared to the 10 billion year age of the star. This is inaccurate. The nebula lasts approximately 1.5e-4 of the life of the star. On the other hand, the human eye blinks in about 350 milliseconds, so if the average person lives about 70 years, an eyeblink represents 1.6e-10 of a human life. So the nebula has survived for more than one million cosmic eye blinks, or about a half a cosmic week. This does not detract from the amazing longevity of the nebula, nor its beauty.

I apologize for taking away from the beauty of today's APOD picture but several years ago I had a situation that exactly resembled the frantic scurrying seen in the above little methuselah. My daughter and I exterminated a cockroach colony we found in a little shed at the back of the yard - their behavior, upon being hit with the spray, was exactly like that .....

math follows life follows math once again!!!

Pretty impressive; this nebula lasted 7 to 15 times an average nebula!

What kept it intact for such a long time?

FRED (@ 35426) is a methuselah:

<<Conway's Game of Life, also known as the Game of Life or simply Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. It is the best-known example of a cellular automaton.

A methuselah is a pattern that takes a large number of generations in order to stabilize (known as its lifespan) and becomes much larger than its initial configuration at some point during its evolution. In particular, patterns that grow forever are not methuselahs. Fred is a methuselah with a lifespan of 35426 generations, discovered by Schneelocke on May 15, 2010, using Nathaniel Johnston's soup search script,only the second pattern ever to be found this way with a longevity greater than that of Lidka, and the first with a lifespan greater than that of Edna. It is currently the longest-lived known methuselah to fit within a 20×20 bounding box.>>

Explanation: Based on its expansion rate the nebula has an age of 150 thousand years, a cosmic blink of an eye in the 10 billion year life of a sun-like star. But planetary nebulae represent a very brief final phase in in stellar evolution, as the nebula's central star shrugs off its outer layers to become a hot white dwarf. In fact, planetary nebulae ordinarily only last for 10 to 20 thousand years.

Pretty impressive; this nebula lasted 7 to 15 times an average nebula! What kept it intact for such a long time?
