"The creation of Adam"

We all are children of supernovae
The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The heaviest elements, like iron, however, are only formed in the massive stars which end their lives in supernova explosions. Even heavier elements are born in the extreme conditions of the explosion itself.
Without dying stars, life would not be possible. Our blood has iron in the hemoglobin which is vital to our ability to breath. We need oxygen in our atmosphere to breathe. Nitrogen enriches our planet's soil.
Without supernovae, we can have gas planets, stars and galaxies but not cars, cows, solid planets, humans or any life. We all are children of supernova explosions.
Simeis 147, a supernova remnant in constellation Taurus
Technical details and other info about the Simeis 147 (Sh2-240) can be seen in my blog post here:
I finalized this image at February 2012, the total exposure time is about 30h.

The very large, 18-panels, mosaic of the Cygnus was my main work at Autumn season 2011.
I named it to the Chinese Dragon Nebula due to reason seen in the image above.
Image spans 22 degrees horizontally. (22 degrees = 44 full Moons side by side in the sky)
Original blog post about Cygnus mosaic, with technical details, can be seen here:
Heart and Soul Nebulae, reprocessed
Since the weather up here has been less than supportive for astronomical imaging for a long time, I have played with an older data.
Heart & Soul Nebulae
IC1805 & IC1848
Image is in HST-palette, (HST=Hubble Space Telescope) from the emission of ionized elements,
R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
My photos, from several years, are used to combine this panoramic image of IC 1805 & 1848.
This emission nebula area is located in constellation Cassiopeia at distance of about 7500 light years.
I have made a scale study to show the apparent scale in the sky, it can be seen here:
Image is in visual spectrum, mixed from the same narrowband material, than image above.

ART
I have seen this phrase somewhere, can't remember when and where though.
Image at the background is imaged at 2011.
It's part of the very large, 18-panel, mosaic image of Cygnus constellation.
Details here: http://astroanarchy.blogspot.fi/2011/12/cygnus-mosaic-18-panels-and-22-x-14.html
I did this, since beside being an astronomical photographer, this is an art form for me.
All my images can be seen in my portfolio: http://astroanarchy.zenfolio.com/
