Messier 78

The Messier 78 nebula (also known as M78 or NGC 2068) is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of objects that same year.

M 78 is the brightest diffuse nebula in the sky, and finding it is as easy as locating Orion's Belt, the famous three-star asterism.

I have analyzed the spectrum of this nebula. In this graph I have looked at which were the highest peaks, to identify what element it is made of. Then I have calculated the area of ​​each peak with respect to the total and these are my results.

To show that these are the correct elements I will attach some photos. To find what each element is, I have used the following web page:

                 HIDROGEN                                       NEON                                       CHROME                                     SELENIUM 


I have searched scientific articles and according to Castellanos p. et al, 2011 the M78 contains hydrogen.
