Infrared Helix Nebula Poster
The Helix Nebula, which is composed of gaseous shells and discs puffed out by a dying sunlike star, exhibits complex structure on the smallest visible scales. In this new image from NASA's Spitzer Space Telescope, infrared light at wavelengths of 3.2, 4.5, and 8.0 microns has been coloured blue, green, and red (respectively). The "cometary knots" show blue-green heads due to excitation of their molecular material from shocks or ultraviolet radiation. The tails of the cometary knots appear redder due to being shielded from the central star's ultraviolet radiation and wind by the heads of the knots.

My Bible verse postcard, turned out excellent. I love it and have it already framed. It was so reasonably priced for something done so well. Thank you to Zazzle and the artist! I thought it looked exactly like what I ordered. Perfect.

Poster is printed clearly, good quality . Inclusive of many prints .
The shipping was the problem. Box was flimsy and item got bent.. only suggestion would have been to put in a canister or mark fragile. Printing was exactly as shown

I am a fan of Ravens and needed to have a poster of my favourite bird. The image quality is sharp.
