The unique planetary nebula NGC 2818 is nested inside the open star cluster NGC 2818A. Both the cluster and the nebula reside over 10,000 light-years away, in the southern constellation Pyxis (the Compass).
This Hubble image was taken in November 2008 with the Wide Field Planetary Camera 2. The colors in the image represent a range of emissions coming from the clouds of the nebula: red represents nitrogen, green represents hydrogen, and blue represents oxygen. — Tom’s Astronomy Blog » Blog Archive » Hubble’s Look at NGC 2818

I can never get enuff of these pics.
I’ve got a collection of NASA pics that cycle as my screen saver. Maybe someday I will submit some to MCS if I ever have time.
