About This Design

Helix Nebula by Hubble Postcard

Helix Nebula by Hubble Postcard

Helix Nebula by Hubble. The Helix Nebula is thought to be shaped like a prolate spheroid with strong density concentrations toward the filled disk along the equatorial plane, whose major axis is inclined about 21° to 37° from our vantage point. The size of the inner disk is 8×19 arcmin in diameter (0.52 pc); the outer torus is 12×22 arcmin in diameter (0.77 pc); and the outer-most ring is about 25 arcmin in diameter (1.76 pc). We see the outer-most ring as flattened on one side due to its colliding with the ambient interstellar medium. Expansion of the whole planetary nebula structure is estimated to have occurred in the last 6,560 years, and 12,100 years for the inner disk. Spectroscopically, the outer ring's expansion rate is 40 km·s−1, and about 32 km·s−1 for the inner disk.

I had never seen these classic science fiction images and most of my friends have not seen them either. They are like little treasures! Amazing quality and fun to send people!

I joined Postcrossing a few months ago and wanted postcards to represent my state well. I found them on Zazzle. I purchased numerous cards and was impressed with all of them. Excellent! The colors are beautiful. The cards have the exact look I wanted. I couldn't be happier.
