APOD: 2019 September 29 - MyCn 18: The Engraved Hourglass Planetary Nebula

Good Sunday Morning Maj William W. 'Bill' Price, and thank you for your APOD!!! My wife & I are still on Cape Cod, MA after a marvelous day yesterday with my Son, Jeff, & my daughter-in-law, Kim... All I have with me is my smartphone, so can't do the research I usually do...that said, I will try to add to my response later... Have a great Sunday, Bill! Arrived home around 11am from Beautiful Cape Cod...

There isn't too many video clips available which cover the Hourglass Nebula with an eye in it, but I came up with a short one which provides some interesting views and dynamic photo acoustics...

An hourglass with an "eye" in it. That's quite the picture Maj William W. 'Bill' Price Thanks and good morning.

Good Sunday morning my friend Maj William W. 'Bill' Price and thank you for posting the NASA Astronomy Picture of the Day for Sunday, September 29, 2019 entitled "MyCn 18: The Engraved Hourglass Planetary Nebula" in honor of our friend Cynthia Croft

"Explanation: Do you see the hourglass shape -- or does it see you? If you can picture it, the rings of MyCn 18 trace the outline of an hourglass -- although one with an unusual eye in its center. Either way, the sands of time are running out for the central star of this hourglass-shaped planetary nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a Sun-like star's life occurs as its outer layers are ejected - its core becoming a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope (HST) to make a series of images of planetary nebulae, including the one featured here. Pictured, delicate rings of colorful glowing gas (nitrogen-red, hydrogen-green, and oxygen-blue) outline the tenuous walls of the hourglass. The unprecedented sharpness of the Hubble images has revealed surprising details of the nebula ejection process that are helping to resolve the outstanding mysteries of the complex shapes and symmetries of planetary nebulas like MyCn 18."

The wonderful subject of this image brought to mind that before the Allman Brothers, Duane & Gregg Allman were part of Hourglass.
