Fetal Nebulae

If you look hard enough for something in nature, you'll find it. Whether it's numbers, symbols, shapes, or facsimiles, there is enough randomness about to catch your eye.
This was on Astronomy Picture of The Day for 08/25/08:

It's called NGC 7008, but it's also known as the Fetus Nebula. I thought it was a cool picture given our situation (as well as Allison having ~30 days left!). Of course, the scientific explanation isn't that this is a galaxy being born, it's actually the death throws of an ancient star similar to our sun. Sometimes the reality isn't quite what you'd expect...:)
Here is the caption explaining the photo if you didn't go to the website:
Compact and round, NGC 7008 is recognized as a planetary nebula about 2,800 light-years distant in the nebula rich constellation of Cygnus. This impressive telescopic view shows off NGC 7008's remarkable colors and details by the skillfull combination of broad band and narrow band images from two different telescopes with about 12 hours of total exposure time. The intriguing assortment of features within the nebula's approximately 1 light-year diameter suggest its popular name, the Fetus Nebula, but planetary nebulae are not associated with star birth. Instead, nebulae like NGC 7008 are produced during a brief phase that sun-like stars pass through toward the end of their lives. Ejecting their outer layers, the stars cool to eventually become white dwarf stars, like the star seen near the center of NGC 7008. This colorful image also includes an unrelated but still lovely gold and blue binary star system just below NGC 7008.

That's beautiful! I think I can see it's nose... :)

WTF? Mara's giving birth to a constellation?

Mike - you've out done yourself.

We're still not sure if it's a boy or a girl yet though...is there a difference in constellations?

Wow, you find the craziest things! Only the Syring's would compare their human fetus to a "nebulae"...or whatever that is! :)
