NGC 7009

The so-called Saturn Nebula emerges from the darkness as a series of irregularly shaped bubbles, illuminated in glorious shades of blue and pink. The Saturn Nebula was originally a low-mass star that expanded into a red giant at the end of its life and began to release matter from its outermost layers.

NGC 7009 - Saturn Nebula - Planetary Nebula | freestarcharts.comHere you can find more information.

This is the spectrum that I have studied:

Peak A obtains hydrogen

Peak B obtains scandium

Peak C obtains selenium

Peak D obtains europium

The total area it is of 56773850

Peak A area=3072603 so---------------------

Peak B area=3925248 so---------------------

Peak C area= 3383397------------------------

Peak D area= 7276026 so--------------------

The results are:

5.4% of hydrogen 

6.91% of scandium

5.96% of Selenium 

12.81% of europium

I've been investigating and I have found some interessant things.

First, in this article I discovered that in some nebulas (one of them NGC 7009) scientists have found Molecular Hydrogen Microstructures. That could be an explanation of the presence of H in my investigation.

On the other hand, here I read that the most important chemical elements are Oll, H, C and N. As I said before, I found H but I didn't find the rest of the elements.
