Spectra of Planetary Nebula NGC 7027

The following image is color coded spectra of the planetary nebula NGC 7027 (the "Eskimo" Nebula).

It is computed and plotted in your browser by a Java program which reads a file containing a list of emission line wavelengths and their corresponding strenghts.

Note: This program generates deep 24 bit color plots, therefore you may need to increase the color depth of your system to view subtle details in these spectra.

There may be a small delay as each Applet loads its element emission line file and computes the spectra...
